Like its predecessor, the game pits two teams, the Counter-Terrorists and the Terrorists, against each other in various objective-based game modes. Additional game modes that stray away from this setup are also included. Counter-Strike 2 features major technical improvements over Global Offensive, including a move from the Source game engine to Source 2, improved graphics, and a new “sub-tick” server architecture. In addition, many maps from Global Offensive were updated to take advantage of the features of Source 2, with some maps receiving complete overhauls.
