Chaos Rebels

The complex is divided into 4 zones: surface, offices, heavy zone and light zone.
Surface: The very first zone in the complex. Located on the surface of the complex. Two elevators provide access to the complex: Gate A and Gate B.
Offices: The zone following the surface. A work area for scientists, it has a checkpoint leading to the heavy zone.
Heavy Zone: Mainly used for storage. You can often see elevators, boxes, and brown shades in this zone. There are two elevators leading to the light zone.
Easy Zone: The deepest zone in the complex. This zone contains all SCP objects and a D-class room.

SCP-500 ("Panacea") is a red pill. It completely heals the user of wounds and all negative effects.

SCP-207 ("Cola") is a carbonated beverage resembling a Coca-Cola soft drink that dramatically increases movement speed but gradually deteriorates health.

SCP-207-1 (Anti-Cola) - works completely opposite to SCP-207 - it slows down the user's movements, but makes them stronger and more resilient.

SCP-018 is a super-bouncing ball. Once thrown, it begins bouncing off walls at incredible speed, causing fatal damage to anyone it hits.

SCP-268 is an old cap. When worn, it renders the wearer nearly invisible until they perform an active action.

SCP-244 are two anomalous urns. When deployed, they create a zone of extreme cold, slowing and gradually killing those inside.

SCP-1344 are unusual glasses. They allow improved night vision and the detection of certain hazards, but at the cost of some vision limitations.

SCP-1576 is a can of "pizza." After use, it temporarily grants beneficial effects to the user.

SCP-1853 is a vial of the drug "Productivity." It temporarily enhances the user's combat abilities and reaction time.

SCP-2176 is a radio anomaly. When activated, it emits a powerful electromagnetic pulse that disables nearby electronics.

SCP-127 is a living weapon. A biological automaton capable of speech and capable of self-replenishing its ammunition.
Instead of bullets, it shoots sharp teeth.

D-class prisoners are primarily maniacs, murderers, or other individuals who have received prison sentences. They were offered "service" in the foundation as a way to avoid prison.
D-Class participate in experiments with SCP objects as test subjects. They view the Chaos Insurgency favorably, considering them saviors. Each D-Class member has a serial number beginning with D and up to four digits. Example: D-8384. D-Class wear orange T-shirts/jackets and black wool hats.

The SCP Foundation consists of three parties: Scientists, MTFs, and the complex's security guards.
Scientists are research staff who fulfill the complex's basic requirements. They are a valuable resource for the Chaos Insurgency, as they know the passwords to access the complex.
Security guards are the facility's security personnel, guarding entrances and exits, scientists, and SCP facility chambers. They carry a bulletproof vest, a radio, and a Glock or Beretta pistol.
MTF - Mobile Task Force, arriving at the complex only in emergency situations such as the escape of SCP objects or the invasion of the Chaos Insurgency.
MTFs are armed with: M4-family assault rifles, radios, Glock or USP-family pistols.
MTF Equipment: Tactical helmet, blue combat uniform, black body armor and heavy black boots.
The Foundation is hostile to the Chaos Insurgency, and D-Class are treated as expendable. Security guards and MTFs have the authority to execute D-Class if they attempt to escape or become disobedient.

Chaos Insurgents are most often D-class or former Foundation scientists who have defected to Chaos. Chaos Insurgents have several goals:
Use anomalies as tools, not just isolate them. Insurgents actively steal SCP objects and use them as weapons, technology, or tools to achieve their goals.
Build a new world by liberating humanity. Rebels often rescue D-class and recruit them into Chaos, while scientists are executed under the pretext that they are "enemies of humanity," just like the Foundation.
Interestingly, the name "Chaos Insurgency" is a bit misleading. They don't seek to create chaos for its own sake. Their operations are usually very well planned: sabotage, theft of anomalies, attacks on Foundation facilities. For them, "chaos" is more a means to destroy the existing order and replace it with a new one.
Chaos Insurgency Equipment: Dark green leather trench coats with beige tactical vest, heavy black boots, dark green combat helmet with red Chaos Insurgency insignia, special forces black gas masks, dark gloves.
The Chaos Insurgency's weaponry: most commonly used are AK or M4 assault rifles, heavy shotguns such as the Saiga-12, AA-12, KS-23, and, in rare cases, M249 heavy machine guns in desert camouflage with modifications.
The Chaos Insurgency treats the D-Class as allies, considering them "victims of circumstance," so they rescue them from the complex and recruit them into the Chaos Insurgency.
