Rescue hostages, escort VIPs to safety, disarm bombs, travel through hostile environments, and more. Both a single and multiplayer game, Counter-Strike: Condition Zero puts a special counter-terrorist operative under your command and you must neutralize any threat that comes along. As a follow-up to Half-Life: Counter-Strike, one of the most successful PC titles of 2000, Counter-Strike: Condition Zero takes the game to a new level.
