SURVIVAL OF THE FITTEST
What you will find in Black Mesa
Gruesome, deadly invaders from other worlds. They came pouring through the portal Gordon opened, and are causing havoc all around the facility.
The Hazardous Environment Combat Unit has been sent in to ‘clean up’ the incident, which means killing everyone.
The boffins who worked at Black Mesa are mostly seen dying in horrible ways, but they can also help you by opening locked doors.
These guys are handy with a pistol, and will follow you around, firing at any enemies you encounter. But they’re weak, so don’t get attached.
Former scientists and security guards, now transformed into shambling, grotesque zombies by the headcrabs that latched onto their faces.
