The game pits two teams against each other: the Terrorists and the Counter-Terrorists. Both sides are tasked with eliminating the other while also completing separate objectives, the Terrorists, depending on the game mode, must either plant the bomb or defend the hostages, while the Counter-Terrorists must prevent the bomb from being planted or to rescue the hostages. There are six game modes, all of which have distinct characteristics specific to that mode. Global Offensive has matchmaking support that allows players to play on dedicated Valve servers, as well as allowing custom maps and game modes via community servers. Global Offensive has a competitive scene, with Valve-sponsored tournaments, known as the “Majors”, being the premier competitive event for the game.
