Half-Life: Opposing Force

Half-Life: Opposing Force is an addition to the original game, where the player controls not Gordon Freeman, but Marine Adrian Shepard. Plot Shepard arrives at the Black Mesa research complex for a “clean-up” after the incident with the resonance cascade. But the operation quickly turns into a struggle for survival.: - aliens from Xen have already taken over the complex; - New Race X creatures are appearing; - the army begins to hide the traces of the disaster, destroying even its own soldiers. The ending of the game leaves Shepard's fate uncertain — he is “frozen” by the mysterious G-Man.
