Escape from Black Mesa

This is an early outline for a Half-Life mini-campaign using the Alien RPG system for the 25th release date of the game in November 2023.
The player characters are scientists, technicians, and security guards employed at the Black Mesa Research Facility whose goal is to simply find a way out of the underground facility and escaping with their lives.

• Chapter 1: The PCs happen to be on the same tram car going to the deepest sections of the facility when the power goes out and they get stuck. After getting out of the tram tunnels, they discover that many machines have exploded and turned much of the area to rubble that obstructs their path to the surface.
• Chapter 2: After getting out of the most heavily collapsed area, the PCs discover alien creatures that are overrunning the facility and attacking personel.
• Chapter 3: When the PCs reach the surface area of the facility at sunset, they encounter soldiers who are fighting the aliens and roughly taking all facility stuff into custody, but don't make any efforts to have them evacuated. They have to escape from their holding area dodging both soldiers and aliens to find a way out on their own.
• Chapter 4: The PCs make it into a disused area of the facility that has an old, sealed-off exit tunnel. As the soldiers are falling back to their extraction areas, the PCs are left alone with the invaders as the environment is turning increasingly alien.
• Chapter 5: The PCs reach the old exit at the morning of the third day as a giant nuclear explosion shakes the ground and becomes visible above the mountain behind them. They have to find a way out of the desert while soldiers are still searching for aliens that escaped the facility before the explosion.
• Chapter 6? After escaping the desert, the PCs reach a town that is devastated by a massive release of energy just as they arrive and unleashed more alien from another dimension upon the world.
