Half-Life: Counter-Strike is a modification for the classic first-person shooter, Half-Life. Because Counter-Strike began as a user modification, it was developed and play-tested by thousands of fans before it was actually released commercially as an official Half-Life update. The Half-Life: Counter-Strike mod alters the multiplayer capabilities of Half-Life to make the game more team-oriented. Up to twenty players are able to compete as terrorist and anti-terrorist squads in this chapter of the continuing Half-Life story.
As the team aspect of the game is so important, Half-Life: Counter-Strike should be primarily considered for its multiplayer features. Players need to work together to accomplish mission goals like rescuing hostages, assassinating a target, or simply escaping an enemy counter-attack. Because Half-Life: Counter-Strike was essentially born online, there are many sites on the Internet to provide both official and unofficial support.
