What is Counter-Strike? Let me break it down for you.
Counter-Strike, the world’s number one online action game series, is a first-person shooter developed by Valve Software, the creators of the renowned Half-Life series. This team-oriented online shooter pits terrorists and counter-terrorists against one another in round-based combat set all over the world. Using the power of the “Source” engine, the original Counter-Strike has been completely remade as Counter-Strike: Source—offering upgraded graphics, levels, and the implementation of a new physics engine. Counter-Strike will never be the same!
First released to the public on June 18th, 1999, Counter-Strike began as a simple fan-produced mod for Half-Life. Thanks to a series of steadily-improving beta releases, the mod started to foster a progressively-enlarging and dedicated following. As the fast-paced, tactical game play was refined and improved, and as new concepts and maps were introduced, Counter-Strike moved from being a mere Half-Life mod to an entirely new game.
With the release of Steam, Valve's digital content delivery system, Counter-Strike found a new footing within the gaming community. Counter-Strike’s first single-player chapter, Counter-Strike: Condition Zero (Developed by Valve and Turtle Rock Studios), was a great success, bringing many new features and upgraded graphics to the classic game. The release of Counter-Strike: Source only helped boost the series further towards its now legendary status. Counter-Strike is about as close as you’ll ever get to saving the world; or destroying it!
