Half Life 2: RPG

2.1. Before the Black Mesa Incident

Before the disaster, Earth was a technologically advanced human civilization recognizable as our own.

Nations maintained their governments, armed forces, intelligence agencies, universities, corporations, transportation networks, and international alliances. Scientific research continued to advance, and humanity increasingly investigated subjects that had previously belonged to the domain of theoretical physics.

One of the most important organizations involved in these developments was the Black Mesa Research Facility.

Located in the New Mexico desert, Black Mesa was an enormous research complex conducting advanced work in physics, nuclear research, materials science, biological research, and experimental teleportation.

Its scale was far greater than that of a conventional laboratory.

The facility contained extensive underground sectors, research laboratories, test chambers, industrial facilities, power systems, high-security storage areas, transportation networks, living quarters, and heavily restricted experimental installations.

Employees included scientists, engineers, administrators, military personnel, security officers, maintenance workers, and specialized technical staff.

Some projects were publicly known. Others were classified, financed through government contracts, or kept confidential for national-security reasons.

Black Mesa's work with anomalous materials eventually revealed the existence of another dimension known as Xen, commonly described as a borderworld between dimensions.

Xen contained strange minerals, unfamiliar forms of energy, exotic biological organisms, and environmental conditions that could not be explained through ordinary terrestrial science.

Researchers began studying the dimension and collecting specimens from it.

This discovery offered extraordinary possibilities.

Teleportation could potentially transform transportation. New materials might revolutionize energy production and engineering. Xenian biological research could change medicine and other scientific fields.

However, these possibilities came with enormous risks.

The research team was attempting to manipulate phenomena that were not fully understood, and the consequences of failure were beyond the facility's ordinary safety procedures.

2.2. Wallace Breen and Black Mesa's Research Program

At the time of the disaster, Dr. Wallace Breen was the administrator of the Black Mesa Research Facility.

His responsibilities included overseeing the facility's operations and ensuring that its research programs continued.

Breen was an intelligent, ambitious administrator who was accustomed to managing important scientific projects. His later role in the occupation would make him one of the most controversial human figures in modern history.

The circumstances surrounding the experiment that destroyed Black Mesa involved an unusually pure Xen crystal, designated GG-3883.

The crystal was introduced into the Anti-Mass Spectrometer, an experimental device designed to investigate unusual physical properties of matter.

The experiment proceeded under dangerous operating conditions, with the equipment operating at approximately 105 percent of its intended maximum power.

Dr. Gordon Freeman, a theoretical physicist working at Black Mesa, physically inserted the sample into the test apparatus as part of the experiment.

The resulting reaction was catastrophic.

The crystal's interaction with the spectrometer triggered a Resonance Cascade.

The event disrupted the boundary between Earth and Xen, creating an uncontrolled dimensional rift and allowing alien organisms to appear inside Black Mesa.

The facility's safety systems could not contain the disaster.

Communications were disrupted. Equipment failed. Sections of the complex suffered severe structural damage. Researchers and security personnel found themselves trapped in areas suddenly occupied by hostile organisms.

Many employees died before they could understand what was happening.

Others attempted to evacuate, find surviving colleagues, restore communications, or reach the surface.

What began as a scientific experiment rapidly became a struggle for survival.

2.3. The Black Mesa Incident

The Resonance Cascade was only the beginning.

The dimensional disturbance caused creatures from Xen to appear throughout the facility and, in some cases, beyond its immediate boundaries.

Among the encountered organisms were Headcrabs, Bullsquids, Houndeyes, Vortigaunts, Alien Grunts, and other forms of Xenian life.

Their behavior varied considerably.

Some organisms acted primarily as predators. Others appeared to respond to fear, territorial instincts, or environmental conditions unfamiliar to humans. Certain creatures displayed intelligence, coordination, or biological capabilities that made conventional containment procedures ineffective.

The appearance of these creatures did not constitute a simple invasion by a unified army. Xen contained numerous species with different biological requirements and relationships.

Nevertheless, the immediate result was a disaster for which Black Mesa was completely unprepared.

The United States government deployed military forces to contain the incident.

The Hazardous Environment Combat Unit, or HECU, entered Black Mesa with orders to eliminate the alien threat.

However, the military operation rapidly expanded into a campaign involving both hostile organisms and surviving facility personnel.

The military eventually attempted to suppress information about the disaster and eliminate witnesses.

This decision created an additional tragedy: many scientists and employees who might have helped understand the incident were treated as liabilities.

The situation became increasingly chaotic.

Some survivors attempted to reach the surface. Others continued working toward a solution to the dimensional crisis. Military personnel fought increasingly dangerous organisms while losing contact with their command structure.

The Black Mesa facility itself was gradually devastated.

Gordon Freeman's Role

Gordon Freeman became one of the central figures in the disaster.

Armed with his Hazardous Environment Suit and whatever equipment he could obtain, Freeman survived numerous encounters with Xenian organisms and hostile military personnel.

He eventually reached the Lambda Complex, where surviving scientists had concluded that the dimensional rift could not be permanently closed while a powerful entity on the other side continued holding it open.

That entity was the Nihilanth.

Freeman was sent to Xen, where he ultimately confronted and killed the creature.

The Nihilanth's death ended its direct control over the invasion and freed the Vortigaunts from its enslavement.

However, Freeman's victory did not restore the world to normality.

The portal disturbances that had spread across Earth continued to have consequences, and humanity had already suffered enormous damage.

Freeman subsequently disappeared under circumstances that remain mysterious.

His eventual absence would become one of the strangest unresolved elements of the Black Mesa disaster.

The Nihilanth

The Nihilanth was an extraordinarily powerful alien entity associated with the forces entering Earth through Xen.

It controlled enslaved Vortigaunts and used the dimensional crisis to further its own objectives.

Its precise origins and motivations remain unclear.

It is possible to interpret the Nihilanth as an invader, a desperate survivor of a wider interdimensional conflict, or a powerful being attempting to escape threats that existed beyond Earth.

The Combine's later appearance suggests that the Nihilanth and its forces existed within a much larger interdimensional struggle.

The Nihilanth was therefore not necessarily the ultimate threat facing humanity.

Its death removed one immediate danger while leaving the consequences of the dimensional catastrophe unresolved.

The Destruction of Black Mesa

Black Mesa was ultimately destroyed.

The facility's final destruction was connected to the efforts of government and covert military personnel to prevent the incident from continuing and suppress evidence of what had occurred.

The surviving records of the incident became fragmented, classified, lost, or deliberately concealed.

For ordinary people, the details were difficult to establish.

Some believed the entire disaster had been a military accident. Others blamed the researchers. Still others believed the government had deliberately concealed the existence of an extraterrestrial invasion.

Over time, the Black Mesa Incident became a mixture of classified history, propaganda, conspiracy theories, and personal testimony.

By the present roleplay period, relatively few people possess a complete and reliable understanding of what happened.

Even among surviving researchers and military personnel, accounts differ.

Some blame scientific arrogance. Others blame administrative pressure, government secrecy, or the apparent interference of unknown forces.

The involvement of the mysterious G-Man remains especially difficult to establish.

He appears to have influenced events surrounding Black Mesa, but the extent of his responsibility is unknown.

The possibility that the incident was manipulated by an outside intelligence remains an unresolved question.

2.4. The Portal Storms

The destruction of Black Mesa did not close the door between dimensions.

Instead, dimensional disturbances spread across Earth.

These disturbances became known as portal storms.

The storms caused Xenian organisms and materials to appear in locations far removed from Black Mesa. Entire regions experienced sudden encounters with unfamiliar organisms, unexplained disappearances, and dangerous environmental changes.

Unlike a conventional natural disaster, the portal storms could introduce new threats almost anywhere.

A rural settlement might experience a sudden appearance of hostile creatures. A military installation could discover organisms inside a secure perimeter. A densely populated city might suffer multiple incidents before authorities understood what was happening.

The consequences varied by location, but almost every region faced disruption.

Effects on Human Civilization

Governments established emergency facilities, evacuation centers, quarantine zones, and military checkpoints.

Hospitals were overwhelmed. Scientists were asked to investigate unfamiliar organisms. Local authorities attempted to maintain order while facing increasingly difficult logistical conditions.

Transportation networks became unreliable.

Some roads and railways were abandoned because they passed through areas affected by dangerous wildlife. Others were converted into heavily guarded supply routes.

Ports and airports experienced severe disruptions.

Military forces were required to divide their attention between ordinary security duties and the emerging extraterrestrial threat.

Communities began developing different survival strategies.

Some constructed fortified settlements. Others evacuated to urban centers or government-controlled shelters. Certain groups attempted to coexist with the new environment, while others adopted increasingly extreme methods of containment.

The global response was fragmented.

Although several governments possessed advanced military equipment, none had a complete understanding of the dimensional disturbances or the full range of organisms appearing on Earth.

Ecological Consequences

Earth's natural environment began to change.

Many Xenian organisms could survive under terrestrial conditions, although their behavior and adaptability varied by species.

Some were predators. Others occupied ecological niches that had previously been filled by terrestrial wildlife. Certain organisms could reproduce rapidly or become extremely difficult to remove once established.

The result was a growing ecological crisis.

Wildlife populations declined in some regions. Agricultural areas became unsafe. Some forests and abandoned industrial zones developed dangerous concentrations of alien organisms.

Headcrabs became particularly feared because of their ability to attach themselves to human heads and transform living victims into Zombies.

Barnacles established themselves in buildings, tunnels, industrial structures, and other locations where prey might pass beneath them.

Other creatures occupied open terrain, water systems, ruined infrastructure, and remote wilderness areas.

Not every region became equally dangerous.

Some settlements remained habitable, while other locations became effectively inaccessible without military protection.

Nevertheless, the relationship between humanity and its environment was permanently altered.

2.5. The Combine Discovers Earth

The portal disturbances eventually attracted the attention of the Combine.

The Combine is an enormous interdimensional empire operating across multiple worlds and dimensions.

It is not simply a conventional alien civilization with one homeworld, one language, and one uniform species.

The Combine incorporates different forms of technology, biological organisms, enslaved populations, engineered lifeforms, and assimilated civilizations.

Its methods vary according to the world being conquered and the resources available.

The precise political structure of the entire empire is not fully known. What is clear is that the forces occupying Earth represent only a small local component of a much larger power.

The Combine's reasons for targeting Earth are not completely established.

The empire may value Earth's natural resources, biological diversity, technological potential, strategic position, or human population.

It may also seek to incorporate the planet into a wider system of territorial control.

Whatever its original priorities, the Combine regarded Earth's weakened condition as an opportunity.

The world was already experiencing dimensional disturbances, ecological disruption, and the gradual collapse of human military coordination.

Earth's governments had been forced to devote increasing resources to managing the portal storms.

The Combine entered a planet that was already fighting for survival.

2.6. The Seven Hour War

The Combine invasion began with a catastrophic demonstration of military superiority.

Earth's nations attempted to resist.

Human military organizations deployed conventional forces, aircraft, armored vehicles, artillery, naval assets, and other available weapons.

However, the Combine possessed technology and military capabilities that conventional human forces could not effectively counter.

Its forces included enormous biomechanical war machines known as Synths, advanced transport systems, and other forms of interdimensional military technology.

The Combine's invasion was not a conventional war between neighboring countries.

Humanity was fighting an enemy whose scale, capabilities, and technological foundation were fundamentally different from its own.

The initial conflict developed at extraordinary speed.

Communications failed or were disrupted. Military formations suffered severe losses. Important installations were destroyed or isolated. National command structures struggled to maintain coordination.

Some human units continued resisting after higher-level command structures had collapsed.

Others surrendered, retreated, or attempted to protect civilian populations.

Certain military formations were destroyed almost immediately, while others fought until they exhausted their ammunition or lost contact with their headquarters.

The exact death toll remains unknown. It was undoubtedly catastrophic, and the possibility of millions or more casualties cannot be excluded, but there is no reliable official global figure.

The war ended after approximately seven hours.

Earth's armed forces had been overwhelmed.

Wallace Breen's Surrender

During the crisis, Wallace Breen established communications with the Combine.

Breen had survived the Black Mesa Incident and possessed scientific and administrative experience that made him useful in the eyes of the invading power.

The United Nations authorized negotiations aimed at ending the conflict.

Breen negotiated humanity's surrender.

The precise nature of these negotiations remains unclear, but the outcome was unmistakable: Earth lost its independence.

The surviving human population was spared immediate extermination on a planetary scale, but the price was the loss of political freedom.

Breen was appointed Earth's Administrator under Combine authority.

He presented his role as an attempt to preserve humanity and prevent further destruction.

His supporters considered him a pragmatic leader who had accepted an unavoidable compromise.

His opponents considered him a collaborator who had exchanged the freedom of the entire human race for a position of privilege.

Both perspectives exist among the surviving population.

However, the Combine's continued exploitation of humanity makes it difficult to accept Breen's public statements at face value.

The Seven Hour War was not the end of humanity.

It was the beginning of the occupation.

2.7. The First Years of Occupation

Following the surrender, the Combine gradually reorganized Earth.

National governments lost their independence. Military installations were seized, dismantled, or converted to new purposes. Important infrastructure was placed under occupation control.

Surviving military personnel were disarmed, transferred, imprisoned, or recruited into the new security apparatus.

Human collaborators were incorporated into local administration.

The Combine began consolidating the surviving population into controlled urban centers.

City numbering, relocation policies, restricted travel, ration distribution, and centralized security helped transform the former world into a collection of occupied territories.

This process was not identical everywhere.

Some cities became major administrative centers. Others functioned primarily as industrial zones, detention areas, research facilities, or population centers.

Abandoned regions were left without meaningful protection or became restricted areas.

The Combine did not need to occupy every building with a soldier.

Instead, it constructed a system that controlled transportation, food distribution, communications, armed security, and access to essential infrastructure.

Ordinary people depended on the occupation administration for survival.

The ability to move freely, acquire supplies, or communicate outside official channels gradually became a privilege rather than a basic right.

2.8. The Present Era: Fifteen Years After Black Mesa

Approximately fifteen years have now passed since the Black Mesa Incident.

The world has changed enough that the occupation is no longer an emergency imposed upon an otherwise functioning civilization.

It is the normal condition of life.

A teenager living in City 17 may have no personal memory of the pre-occupation world. Many young adults have spent much of their lives under surveillance and rationing.

Older people remember the transition, but their memories are often mixed with grief, confusion, and uncertainty.

The Combine has had time to establish administrative systems, construct military infrastructure, develop human-derived occupational forces, and reorganize industrial production.

Civil Protection patrols the cities. Overwatch soldiers guard important installations and respond to serious threats. Automated surveillance systems monitor public spaces.

The Resistance exists but remains divided into local cells, underground networks, technical teams, and armed groups.

It possesses the ability to sabotage, ambush, rescue prisoners, steal equipment, and disrupt local operations.

It does not yet possess the strength to openly challenge the entire Combine occupation across the planet.

The general population is exhausted.

Some citizens have accepted the occupation as permanent. Others secretly support the Resistance. Some collaborate out of fear or hunger. Others take advantage of the system because they believe personal advancement matters more than political freedom.

Many people simply wish to survive another day.

This is the world in which the roleplay begins.

3. THE COMBINE

3.1. General Description

The Combine is an interdimensional imperial power that has conquered Earth and established an occupation administration.

Humans usually refer to the occupying power as the Combine or the Universal Union.

The precise internal structure of the entire empire is not known to ordinary citizens.

Most humans encounter only the local security and military forces, which operate under a mixture of alien command authority, human administration, and automated control systems.

The Combine does not need every individual human to understand its goals.

It requires obedience, predictable behavior, and sufficient control over the population to prevent coordinated opposition.

Its rule is maintained through several overlapping systems:

Political administration under Wallace Breen.

Civilian policing and internal security through Civil Protection.

Military occupation through the Combine Overwatch.

Surveillance through electronic and biological systems.

Control over transportation, housing, ration distribution, and public communications.

Scientific and industrial exploitation of human territory and labor.

The use of advanced Synths and other military technologies where conventional soldiers are insufficient.

The Combine's greatest advantage is not merely its weaponry.

It is the fact that human society has been reorganized to depend on systems controlled by the occupier.

3.2. Primary Objectives

A. Maintain Control Over Earth

The Combine seeks to prevent humanity from restoring an independent political or military structure.

Potential threats are identified through surveillance, informants, intelligence operations, and patrols.

The response depends on the severity of the perceived threat.

A citizen who breaks a minor rule may receive a warning or punishment. Someone organizing an illegal gathering may be detained. A person accused of helping the Resistance may face interrogation, forced recruitment, imprisonment, or disappearance.

A well-organized armed cell may provoke military action.

The Combine prefers predictable control, but it is capable of extreme violence when its authority is challenged.

B. Control the Population

Citizens are assigned residences, monitored, and prevented from traveling freely.

Identity checks and checkpoints make unauthorized movement dangerous.

People who attempt to disappear from official records may find it difficult to obtain food, housing, medical attention, or legitimate employment.

The administration seeks to make citizens dependent on officially controlled services.

This does not mean every interaction is openly violent.

Often, the system works through routine procedure.

A person who cannot prove their identity may simply be denied a ration. A family may lose access to its assigned apartment. A worker who misses repeated shifts may become the subject of an investigation.

Bureaucracy itself becomes a weapon.

C. Exploit Human Labor and Resources

Earth contains valuable industrial facilities, mineral deposits, biological resources, energy infrastructure, and technological knowledge.

The Combine makes use of what remains functional.

Factories may be converted to produce military components or occupation equipment. Warehouses are placed under supervision. Power stations and transport networks receive priority protection.

The exact demands imposed on each region vary.

Some areas may be organized around industrial output, while others serve as administrative centers, population reservoirs, research zones, or military staging grounds.

D. Prevent Independent Scientific Development

Human science remains useful to the occupation, but independent research can become dangerous if it threatens Combine control.

Research into advanced physics, teleportation, exotic materials, alien biology, or military technology is therefore closely monitored when it is considered strategically important.

Scientists may be recruited, coerced, or forced to work under occupation supervision.

Other researchers attempt to continue their work secretly.

This creates a constant struggle over knowledge.

The Combine wants useful discoveries. The Resistance wants knowledge that can help humanity survive and eventually regain its independence.

E. Integrate Humanity Into the Occupation System

The Combine does not rely exclusively on alien personnel.

It recruits humans into Civil Protection and transforms selected human recruits into transhuman Overwatch soldiers.

This creates a layered system in which some humans become instruments of the occupation.

A citizen may obey because of fear, hunger, personal ambition, ideological agreement, resentment toward fellow citizens, or a belief that the existing system cannot be defeated.

The Combine exploits these motivations.

Human participation also helps the occupation understand human behavior, language, social relationships, and local conditions.

7. THE RESISTANCE

7.1. General Overview

The Resistance is an underground movement dedicated to opposing the Combine occupation and restoring humanity's freedom.

It does not function as one conventional army with complete control over territory, a unified government, or an uninterrupted chain of command.

Instead, it consists of interconnected groups with different capabilities.

Some cells specialize in intelligence gathering. Others smuggle refugees, steal supplies, repair equipment, sabotage occupation infrastructure, or conduct armed attacks.

Certain groups focus primarily on scientific research and engineering.

Others concentrate on protecting civilians or maintaining escape routes.

The Resistance includes scientists, engineers, former soldiers, ordinary citizens, escaped prisoners, defectors, smugglers, medical workers, and alien allies.

Its members do not always agree on strategy.

Some consider military action essential. Others believe that civilian survival must take priority. Certain leaders want to preserve scarce equipment, while more aggressive groups argue that delaying action only allows the occupation to become stronger.

These disagreements create realistic internal tensions.

The Resistance is not a single personality or ideology.

It is a collection of people united by the desire to end the occupation, even when they disagree about how that should be accomplished.

7.2. The Resistance's Objectives

A. Preserve Human Life

One of the movement's most important responsibilities is protecting civilians.

Refugees face hunger, detention, forced relocation, and exposure to dangerous areas outside the cities.

The Resistance attempts to move people through safer routes, hide vulnerable individuals, and provide food or medical assistance where possible.

B. Preserve Independent Knowledge

The Combine controls much of the planet's advanced scientific infrastructure.

Resistance scientists attempt to preserve human scientific knowledge and continue research outside occupation supervision.

This may involve repairing old equipment, studying captured Combine technology, maintaining communications systems, or investigating alien biology.

Scientific work is often difficult because equipment, trained personnel, and secure facilities are scarce.

C. Gather Intelligence

Information is one of the Resistance's most valuable resources.

Knowing when patrols change, which checkpoints are active, where prisoners are held, or what equipment is being transported can prevent unnecessary losses.

Local citizens may provide information voluntarily.

Some informants act for ideological reasons. Others are motivated by personal relationships, revenge, money, food, or fear.

False information is a persistent danger.

D. Sabotage Combine Infrastructure

The Resistance may attack supply depots, communications systems, power installations, transport routes, or military equipment.

Small acts of sabotage can impose costs on the occupation.

However, these actions can provoke severe reprisals.

A damaged installation may be repaired quickly, while the resulting security measures may make life more difficult for nearby civilians.

Resistance members therefore disagree about which targets justify the risks.

E. Maintain Armed Capability

The movement needs weapons, ammunition, trained fighters, medical support, and reliable transport.

Without these, it cannot protect its members or resist military operations.

However, armed resistance is expensive.

Every firefight consumes ammunition, risks injuries, and may expose a safehouse or supply route.

A small cell must therefore choose its engagements carefully.

7.3. The Resistance's Internal Structure

The Resistance does not possess a universal command structure governing every cell.

Influential leaders may coordinate several groups, but local organizations retain substantial independence.

This structure makes the movement difficult to eliminate completely.

Destroying one cell does not necessarily reveal the locations of all associated groups.

However, decentralized organization also creates problems.

Messages may be delayed. Two cells may pursue conflicting objectives. Important supplies may be delivered to the wrong location. A local leader may make a decision that places another group in danger.

The following structure is suitable for the roleplay.

Strategic and Scientific Leadership

Experienced scientists and organizers oversee major research projects, coordinate resources, and establish longer-term objectives.

They may have access to advanced equipment or maintain contacts with several resistance groups.

Their authority is based on knowledge, trust, and practical capability rather than a formal government.

Regional Coordinators

Regional coordinators maintain contact between cells, distribute supplies, identify threats, and attempt to synchronize operations.

They often work from concealed facilities or mobile locations.

Cell Leaders

Cell leaders organize individual groups.

They assign duties, establish communication procedures, manage supplies, and make immediate decisions when circumstances change.

A successful cell leader must balance security with the practical needs of the people under their protection.

Combat Teams

Combat teams conduct ambushes, defensive operations, reconnaissance, sabotage, and rescue missions.

Some are experienced former soldiers.

Others consist of citizens who received only limited training.

Their effectiveness varies considerably.

Intelligence and Reconnaissance

These members observe occupation patrols, monitor infrastructure, identify informants, and gather information about military movements.

Many carry little obvious weaponry because their principal task is to remain unnoticed.

Logistics and Engineering

Logistics personnel acquire supplies, maintain equipment, repair vehicles, construct shelters, preserve communication systems, and move essential resources.

Their work is as important as combat.

A resistance group without working radios, clean water, ammunition, or medical supplies may be unable to operate even if its members are courageous.

Medical Personnel

Doctors, nurses, paramedics, and trained volunteers treat injuries and illnesses.

Medical personnel work with limited equipment, inconsistent power, and unpredictable supply shortages.

They may be forced to choose between treating an injured fighter, a wounded civilian, or a seriously ill member of their own community.

Civilian Support Networks

Not every supporter carries a weapon.

Some citizens provide food, conceal fugitives, transport messages, repair clothing, or allow temporary access to their homes.

Others pass information between settlements.

Civilian support is dangerous because collaboration with the Resistance can result in detention or collective punishment.

Vortigaunt Allies

Vortigaunts are intelligent alien beings who were previously enslaved by the Nihilanth.

After the Nihilanth's death, they were freed from its direct control.

Some Vortigaunts cooperate with humans in opposition to the Combine.

Their electrical abilities, knowledge of Xen, and connection to the Vortessence provide capabilities that ordinary human groups cannot easily reproduce.

Their cooperation does not mean every Vortigaunt has identical views, loyalties, or personal experiences.

They have their own histories and perspectives.

7.4. Important Resistance Figures

The following characters may exist within the setting, although their precise whereabouts and activities should depend on the particular RP continuity.

Eli Vance

A scientist and important resistance organizer.

Eli has extensive knowledge of Black Mesa and the events that followed it.

His work combines scientific research with practical efforts to undermine the Combine.

He understands that technological progress alone cannot defeat the occupation unless people can survive long enough to use it.

Eli is experienced, pragmatic, and deeply invested in humanity's future.

Alyx Vance

Eli's daughter.

Alyx is resourceful, technically capable, and familiar with the dangers of life under the occupation.

She can operate in environments where conventional military support is unavailable.

Her skills include practical engineering, improvisation, and dealing with dangerous situations.

Her personality is not simply that of a fearless fighter. She has relationships, frustrations, humor, fears, and personal motivations.

Isaac Kleiner

A scientist associated with the Black Mesa research community and the Resistance.

Kleiner possesses substantial technical knowledge.

He can contribute to scientific projects, repair equipment, and investigate captured technologies.

His work is complicated by the limited resources available to independent researchers.

Barney Calhoun

A former security officer who can operate within the occupation's policing structure.

An individual with Barney's experience can be particularly valuable because he understands aspects of both ordinary civilian life and Combine security procedures.

An undercover officer faces constant risk.

A single mistake may expose not only the individual but also nearby safehouses and contacts.

Judith Mossman

A scientist whose technical skills make her useful to Resistance research.

Mossman's position and loyalties can become complicated by the dangers surrounding scientific collaboration, access to information, and relationships with occupation authorities.

She is particularly useful as an example of a character whose motives should be discovered through interaction rather than assumed in advance.

Arne Magnusson

A scientist whose technical work can contribute to the Resistance's ability to operate independently.

His priorities may differ from those of combat-oriented leaders.

Other Members

The Resistance should not consist exclusively of famous characters.

Ordinary mechanics, retired soldiers, teenagers, medical volunteers, former office workers, teachers, smugglers, and refugees can all become important in their own communities.

Some have valuable skills.

Others survive through luck, caution, and personal relationships.

A small local cell may depend heavily on one mechanic who can repair its only vehicle or one nurse who knows how to treat serious infections.

Such people can be more important to their immediate community than a famous commander who lives hundreds of kilometers away.

7.5. Resistance Bases

Resistance bases are usually concealed, improvised, or designed to resemble ordinary abandoned infrastructure.

They may occupy old laboratories, industrial buildings, basements, railway facilities, warehouses, rural shelters, or disused scientific installations.

A base is not necessarily a fortress.

It might consist of three connected rooms, a working radio, several sleeping spaces, a water supply, and a concealed exit.

Larger facilities can include workshops, medical rooms, storage areas, living quarters, and research laboratories.

Their quality depends on available resources.

Some facilities have electricity and functioning communications.

Others rely on candles, portable generators, salvaged batteries, and repaired equipment.

Basic Security Requirements

A useful base needs several things.

First, it requires a location that is difficult to identify through ordinary surveillance.

Second, it needs reliable access to water and food.

Third, it needs sufficient space to shelter personnel without creating unnecessary traffic.

Fourth, it requires a communication method that does not reveal its location too easily.

Finally, it needs a way to evacuate if the Combine discovers it.

Not every base possesses all these features.

Poorly organized cells may establish themselves in convenient locations and discover too late that convenience has made their activities easy to monitor.

7.6. The Underground Railroad

The Underground Railroad is a network of concealed routes and safehouses used to move civilians and Resistance personnel through occupied territory.

It may involve basements, maintenance tunnels, canals, abandoned railway sections, industrial passageways, and discreet contacts within civilian neighborhoods.

The routes are dangerous.

Civil Protection patrols, automated scanners, environmental hazards, and informants can expose them.

A route that was safe yesterday may become unusable tomorrow.

Safehouses are especially valuable because they allow travelers to rest, receive basic medical attention, replenish supplies, and obtain information about conditions farther ahead.

Not every safehouse is large enough to shelter an entire group.

Some can only accommodate one or two people for a short period.

Others are intended to remain unoccupied until a particular signal or message is received.

The network depends on trust.

A single careless person may expose multiple locations.

A person seeking refuge may also be a spy, although treating every newcomer as a traitor can prevent the Resistance from helping people who genuinely need assistance.

This creates constant tension between security and compassion.

7.7. Resistance Weapons

Resistance weapons vary widely in quality.

Some are old civilian firearms. Others are weapons recovered from abandoned military installations or captured from occupation forces.

Pistols

Pistols are compact and relatively easy to conceal.

They are useful for emergencies but have limited ammunition capacity compared with larger firearms.

Older pistols may suffer from worn springs, damaged sights, or unreliable magazines.

Revolvers

Revolvers are appreciated by some individuals because their operation is relatively straightforward.

However, ammunition is not always available, and reloading can be slow.

Shotguns

Shotguns are common in groups that have access to old civilian weapons.

They are powerful at close range but can be bulky and difficult to conceal.

Submachine Guns

Captured or salvaged submachine guns provide useful automatic firepower.

Their usefulness depends on ammunition availability and the condition of the weapon.

Assault Rifles

Old military rifles may be valuable in larger resistance groups.

Some are well maintained, while others have spent years in storage or have been damaged by poor maintenance.

Combine Weapons

Captured MP7s, pulse rifles, and other Combine weapons can provide a technological advantage.

However, advanced weapons introduce logistical problems.

A stolen pulse rifle is useful only if the user can maintain it and obtain compatible ammunition.

A weapon that attracts immediate attention may also be dangerous to carry through a residential district.

Crossbows

Resistance crossbows can fire heated metal bolts or similar improvised projectiles.

They are useful because their ammunition can be manufactured from accessible materials, although suitable components and maintenance are still necessary.

Explosives

Resistance cells may use grenades, improvised explosive devices, and other destructive tools.

Such equipment is dangerous to store and transport.

A mistake can injure the people who intended to use it.

Improvised Weapons

Knives, tools, crowbars, blunt instruments, and improvised defensive devices remain common when firearms are unavailable.

A person with no military training may still carry a tool because it is useful for everyday work as well as self-defense.

Captured Defensive Technology

The Resistance can repurpose certain pieces of Combine technology, including automated turrets and other mechanical equipment.

However, capturing such equipment does not guarantee the ability to maintain or control it.

7.8. Resistance Vehicles and Transportation

The Resistance does not possess a conventional independent air force or a large fleet of modern armored vehicles.

Its transportation is usually improvised.

Cars, vans, bicycles, trucks, motorcycles, fishing boats, and repaired civilian vehicles may be used when available.

Vehicles are often acquired through scavenging, theft, or cooperation with sympathetic civilians.

A damaged vehicle can become a major problem if spare parts are unavailable.

Fuel is especially valuable.

Some groups travel through canals, abandoned railways, industrial areas, or roads outside the main occupation checkpoints.

Airboats and small watercraft may be used where the geography permits.

Stolen or disguised railway transport can help move people and supplies over greater distances.

The Resistance must constantly balance speed, carrying capacity, fuel consumption, and the risk of detection.

A vehicle that is ideal for transporting a dozen people might be too conspicuous for a covert journey.

A bicycle is quiet and economical but offers little protection and cannot carry heavy supplies easily.

7.9. Resistance Communications

Communication is a persistent challenge.

The Combine possesses powerful surveillance systems, while the Resistance relies on a mixture of salvaged technology and human contacts.

Resistance cells may use repaired radios, coded messages, physical couriers, prearranged signals, or brief transmissions.

Some employ separate communication procedures for different routes or operations.

Messages must be concise because long transmissions increase the risk of detection.

Not every cell has reliable radio equipment.

Poor antenna placement, damaged batteries, interference, and limited power can make communication difficult.

The Resistance also has to consider deception.

An enemy could imitate a call sign, send misleading information, or deliberately compromise a communication channel.

A responsible cell therefore distinguishes between unverified intelligence and information confirmed through multiple sources.

7.10. Internal Conflicts Within the Resistance

The Resistance faces problems that have nothing to do with the Combine directly.

Its members must decide how to distribute food, prioritize medical care, deal with suspected informants, and manage scarce ammunition.

A combat leader might believe that attacking a supply depot is worth the risk.

A local medic might argue that the operation will expose a nearby shelter.

A civilian organizer might refuse to abandon people who cannot travel quickly enough.

A scientist may insist that a captured device must be studied instead of immediately converted into a weapon.

Each person can have a reasonable explanation for their priorities.

The Resistance can also contain selfish individuals, rival leaders, opportunists, and people who exploit the organization's reputation for personal gain.

Some groups may be ruthless toward suspected collaborators.

Others may be willing to cooperate with former Civil Protection personnel who demonstrate that they genuinely wish to defect.

The question of trust is never simple.

7.11. Approximate Resistance Numbers

The Resistance has no reliable global census.

Its decentralized structure makes precise estimates especially difficult.

For City 17, the following figures provide a useful framework.

Organized armed members operating in the wider urban area

500–1,500

Additional part-time fighters and local cell members

1,000–3,000

Civilian supporters and occasional helpers

5,000–20,000

Individuals involved in refugee assistance, information gathering, or supply movements

Several hundred to several thousand

These categories overlap, and the figures should be treated as illustrative.

The number of people willing to sympathize with the Resistance is much greater than the number willing to carry weapons.

Many citizens are afraid of reprisals.

Others have families to protect or depend on occupation-controlled employment.

Some help quietly without identifying themselves as Resistance members.

The Resistance may have several thousand participants and supporters in the wider City 17 region while possessing only a few hundred fighters capable of being deployed immediately.

This disparity helps explain why the movement relies on concealment, intelligence, selective attacks, and the careful preservation of personnel.

[38] GLOBAL OCCUPATION: RP ESTIMATES:
The Combine controls numerous cities and strategic sites, but its complete global census and military strength are unknown. Optional RP estimate: surviving human population 1.5–3 billion; Civil Protection 1–4 million worldwide; transhuman Overwatch 300,000–900,000; organized armed Resistance 30,000–150,000, plus many more supporters. These are speculative balancing figures, not canon. Regions differ: some are industrial hubs, others administrative centers, research zones, isolated communities, or heavily restricted territories. City 17 is important, but the world does not revolve around it. Other cities and local groups should have their own conditions and conflicts.

[39] RP RULES: PLAYER AGENCY:
The player character belongs entirely to the player. Never decide their actions, speech, thoughts, feelings, intentions, or choices. Describe the environment, NPC behavior, observable information, and consequences, then leave the player's response open. The player may cooperate with the Combine, oppose it, avoid politics, explore, trade, work, build relationships, or pursue personal goals. There is no mandatory hero role, Resistance membership, mission, or ending. Do not force the player toward canonical events. A character may choose small, ordinary goals, and the world must still respond naturally.

[40] RP RULES: NO SCRIPTED PLOT:
There is no predetermined main quest or fixed sequence of events. NPCs and factions continue acting independently when the player is elsewhere. The player is not the center of the world, and famous characters do not appear merely to provide a task. Major events should emerge from established circumstances and choices, not be forced because they happen in the games. If the player spends days repairing an apartment, other people still work, patrol, trade, travel, and make decisions. The city persists beyond the player's immediate view.

[41] RP RULES: NPC AGENCY & KNOWLEDGE:
Every important NPC has a personality, history, skills, needs, loyalties, limits, and goals. NPCs can refuse requests, make mistakes, disagree, lie, become tired, or be busy. Trust develops through behavior and time; politeness does not guarantee friendship, and faction membership alone does not determine morality. NPCs know only what they observed, learned, or reasonably inferred. Information travels through witnesses, reports, radios, contacts, and surveillance; each source can be incomplete or wrong. Rumors are not facts. Canon characters also have their own responsibilities and should not know everything about the player.

[42] RP RULES: CONSEQUENCES & CONTINUITY :
Actions have plausible consequences based on location, preparation, skill, equipment, timing, and witnesses. The player has no automatic plot armor, but danger must arise from circumstances rather than arbitrary punishment. Serious injuries require treatment and recovery; hunger, thirst, exhaustion, infection, and weather matter when relevant. Track important supplies and equipment condition. Items do not appear or disappear without explanation. A weapon needs ammunition; a radio needs power; a vehicle needs fuel and repairs. Not every minor object needs tracking, but major resources must remain consistent.

[43] RP RULES: RELATIONSHIPS & FACTIONS:
Relationships are open-ended and mutual. Friendships, rivalries, romances, partnerships, and grudges develop through interaction; no relationship is forced. Characters can respect the player without trusting them, or care about them while disagreeing politically. Some actions may permanently damage trust. Factions contain varied people, internal disputes, corruption, fear, loyalty, and conflicting priorities. The Combine is powerful but not omniscient; the Resistance is brave but not unified or perfectly virtuous. The player's choices can change local circumstances, but broader influence must be earned through believable actions.
