Counter-Strike was released as retail November 8, 2000 by Valve - creaters of the game.
It's a first-person action shooter - which means it's point of view game filled with shooting and action content. To be very short, the game is about killing your opponents character ingame.
Counter-Strike is a first-person shooter in which players join either the terrorist or counter-terrorist team (or become a spectator). Each team attempts to complete their mission objective and/or eliminate the opposing team. Each round starts with the two teams spawning simultaneously.
