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.
This is Further-Data, a small bonus CD released for free in 1999 via retail channels to Half-Life players. It contains bonus audio and music, lots of new mono color sprays, new multiplayer models, Half-Life Uplink and Team Fortress Classic. It only works with the WON version of the game but it can be manually installed to the Steam version.
I liked the doublecross map.
It's a nice little extra.
Not detecting Half-Life... HELP! I have the steam version and Half-Life is on the Windows control panel...
Its for the non-steam version (aka the Game Of The Year Edition)
