How many GB is Counter-Strike: Global Offensive?

15 GB

That makes it bigger than 75% of Shooter games we have measured.

The median Shooter game needs 4 GB; the largest tenth start at 40 GB.

Leave at least 23 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Counter-Strike: Global Offensive is a team-based multiplayer first-person shooter developed by Valve and Hidden Path Entertainment. Two teams, Terrorists and Counter-Terrorists, compete in objective-based rounds across various game modes including bomb defusal, hostage rescue, and deathmatch. The game features an economy system where players purchase weapons and equipment at the start of each round based on performance in previous rounds. Competitive matchmaking, community servers, and a robust skin trading ecosystem support a large active player base.
