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. Decay is a cooperative multiplayer game, designed to be played by two people working together to pass through the game's levels.
Cut mission from Half-Life: Decay
Is it just me or is this a cut section of the game?
It is.
It is indeed from the cut mission that only some files were present for. I was hoping this level would get recreated in the mod but it never got update or this extra map in.
