Gordon, supported by colleagues and security guards at the center, faces them in the hopes of surviving and being able to return to the surface for help. The center of Black Mesa is littered with corpses and the invading creatures chase the survivors. The test room is partially destroyed but Freeman, equipped with a “Hazard Suit” (HEV), manages to escape unscathed.

Aliens of various species and races burst across the center and savagely attack his staff.

While participating in an experiment on a mysterious sample, Freeman involuntarily opens an interdimensional gap to a parallel world, Xen, populated by alien creatures. Half-Life follows the adventures of Gordon Freeman, a researcher at the Black Mesa Research Facility, a gigantic, top-secret scientific complex housed in a disused military base totally buried beneath the surface. Half-Life is a first-person shooter developed by Valve Corporation and released by Sierra on Novemfor Microsoft Windows.
