Half-Life: Decay

Gearbox Software, Sierra Entertainment | Released Nov 14, 2001

Half-Life: Decay is the the third expansion pack for the award-winning game, Half-Life. It was included as part of the PS2 version of Half-Life. 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.

Still stretched... I suck at creating banners, so if someone can make me a nice one (950x150), please do so.
