Counter-Strike Condition Zero

Counter-Strike: Condition Zero is the single-player expansion pack to the famed multiplayer game, Counter-Strike. The game uses the aging Half-Life engine.

Counter-Strike: Condition Zero has gone through many incarnations. In April 2001 the game was announced as being developed by Rogue Entertainment. However, that did not last too long and Valve Software took over the development. However, Valve did not have enough time on their hands and handed development off to long time friends Gearbox Software, who knew the HL engine very well. Gearbox started off fresh withoug using content from the Rouge/VALVe version. However, Gearbox did not keep up with development deadlines and the game's release date was pushed back a couple of times before Gearbox dropped the project. In December 2002, Shacknews announced that Ritual Entertainment had picked up development of the game, however community feedback of the game was very negative which made VALVe pull the plug on the project for Ritual. VALVe took on development of the game and paired up with Turtle Rock Studios to create the the Official Counter-Strike Bot.
