Counter-Strike is an objective-based, multiplayer first-person shooter. Two opposing teams—the Terrorists and the Counter Terrorists—compete in game modes to complete objectives, such as securing a location to plant or defuse a bomb and rescuing or guarding hostages.[6][7] At the end of each round, players are rewarded based on their individual performance with in-game currency to spend on more powerful weapons in subsequent rounds. Winning rounds results in more money than losing, and completing objectives such as killing enemy players gives cash bonuses.[6] Uncooperative actions, such as killing teammates, results in a penalty.[8]
