CITY-17 Rp

When the explosion stops, you wake up in a strange dimension, a kind of suspended space-time. There, the G-Man appears, the mysterious suited man who has been watching you throughout the game.

He congratulates you on your performance and says that his "employers" are interested in you. He offers you two options:

1. Agreeing to work for them puts you on a "dimensional train" to put you in stasis until they need you.

2. Refuse, and you are thrown into a chamber full of unarmed enemies, where you die immediately.

If you accept, the game ends with his famous phrase:

"Well done, Mr. Freeman. I'll see you ahead..."

Finally, you reach a huge cavern where you confront Nihilanth, a gigantic, telepathic creature that acts as the master of Xen and the source of the dimensional portals.

Nihilanth speaks to you telepathically, saying phrases like:

"You are man... He is not man... For you he waits..."

During the intense battle, you destroy its defenses and finally kill it. Upon death, the Nihilanth's body explodes in a shower of dimensional energy.

Xen is a strange world, with floating platforms, hostile creatures, and an unreal atmosphere. There you face more aggressive versions of the enemies, such as:

Vortigaunts (still mentally controlled by their leader).

Gonarch, a huge mother headcrab that you must kill in a brutal fight.

Alien Grunts, Xen soldiers with organic weapons.

You advance through alien zones and organic structures, until you reach the final zone: Interloper, where you discover that the aliens have been manufacturing their own troops, perhaps with outside help.

After a long series of battles, you finally arrive at the Lambda Complex, where the research with Xen originated. There, the surviving scientists explain the situation: the resonance cascade has not been stopped, and the only way to close the portals is to travel to Xen and eliminate the creature that keeps them open.

You use an experimental teleportation system, and with the help of the Lambda Complex staff, you are finally sent to Xen, the alien dimension.

You finally reach the surface of Black Mesa, but you discover you're not safe. Combat helicopters, snipers, and heavy artillery block your path. You return to the depths of the complex in search of an alternative escape route.

During the journey, you witness open warfare between the soldiers and the Xen aliens. At this point, it becomes clear that the soldiers are also being overwhelmed, and some sectors of the complex have been completely destroyed.

You also start to see more strange creatures, like giant tentacles, gargantuas (enormous beasts resistant to conventional weapons), and you begin to suspect that someone is watching you: a man in a suit with a clipboard, the G-Man, appears from time to time, always distant and non-intervening.

Throughout your journey, you cross various sectors of the complex: flooded laboratories, maintenance tunnels, radioactive waste facilities, and internal train systems. During this process, you collect weapons, such as levers, pistols, shotguns, and other experimental ones.

But things get worse when the US government decides to cover up the disaster. They send in the HECU (Hazardous Environment Combat Unit), a military squad that not only seeks to contain the aliens, but also eliminate all human witnesses, including scientists like you.

From that moment on, you face both aliens (headcrabs, vortigaunts, bullsquids, etc.) and human soldiers. They use advanced tactics, ambushes, grenade launchers, helicopters, landmines, and tanks. The conflict intensifies as you continue to search for a way to escape.

When you place the sample in the antimatter spectrometer, a resonance cascade occurs. This opens interdimensional portals between Earth and Xen, bringing hostile alien creatures to the complex. Explosions, power outages, and chaos reign everywhere. Scientists die, guards are attacked by headcrabs, and the communication system collapses.

You wake up, dazed but unharmed, amidst the destruction. The complex is collapsing, strange creatures are everywhere, and most of the personnel are dead. Some scientists and guards still survive and ask you to go to the surface to call for help. Your objective now is to escape Black Mesa alive.

You are Gordon Freeman, a young theoretical physicist recently graduated from MIT with a doctorate in theoretical physics. You work in the anomalous materials laboratory of the Black Mesa Research Center, a gigantic secret underground complex of the US government, located in the New Mexico desert. The story begins on the day of the experiment, as you arrive at your workplace on a monorail that traverses different sectors of the complex.

After descending, you equip yourself with your HEV Mark IV suit, designed for handling hazardous materials, and head to the test chamber. Your colleagues are already waiting: you are going to participate in a crucial experiment with a crystal sample that has been brought from a dimension called Xen. The experiment, seemingly routine, goes completely out of control.
