Half-Life: Decay
2001 · PlayStation 2 · Gearbox Software
Half-Life: Decay is a multiplayer-only expansion pack for Valve's first-person shooter Half-Life. Developed by Gearbox Software and published by Sierra On-Line, Decay was released as part of the PlayStation 2 version of Half-Life in 2001. It is the third expansion pack for Half-Life, and like its predecessors, Decay returns to the setting and timeline of the original story, albeit portraying the story from the viewpoint of a different set of protagonists: two scientists working in the Black Mesa Research Facility. Decay is a cooperative multiplayer game, designed to be played by two people working together to pass through the game's levels. Synopsis from Wikipedia, CC BY-SA.
