Counter-Strike: Source (PC, 2005)

Counter-Strike: Source is a tactical first-person shooter video game developed by Valve and Turtle Rock Studios. Released in October 2004 for Windows,[1] it is a remake of Counter-Strike (2000) using the Source game engine. As in the original, Counter-Strike: Source pits a team of counter-terrorists against a team of terrorists in a series of rounds. Each round is won either by completing an objective (such as detonating a bomb or rescuing hostages) or by eliminating all members of the enemy team. The game was initially bundled with all retail and digital copies of Half-Life 2,[3] before being released standalone.
