Two opposing teams, the Terrorists and the Counter-Terrorists, compete in game modes to repeatedly complete objectives, such as securing a location to plant or defuse a bomb and rescuing or capturing hostages. At the end of each short round, players are rewarded based on individual and team performance with in-game currency to spend on other weapons or utility in subsequent rounds. Winning rounds generally rewards more money than losing does, and completing map-based objectives, including killing enemies, gives additional cash bonuses.
Counter-Strike 2 is an update to Global Offensive that uses a new engine to add improved graphics, gameplay mechanics, new lighting and enhanced textures. Some maps were left unchanged while others were enhanced or reconstructed from the ground up.
