How many GB is Overwatch?

50 GB

That makes it bigger than 91% of Shooter games we have measured.

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

Leave at least 65 GB free: games need headroom to unpack updates.

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

Overwatch is a free-to-play first-person hero shooter developed by Blizzard Entertainment. Players choose from a large roster of role-based heroes and compete in 5v5 team matches across various objective-based game modes, with both casual and ranked competitive play. Originally released as Overwatch 2 in 2023 as a successor to the 2016 original, the game was rebranded to simply Overwatch in 2026 with a renewed focus on seasonal narrative content and expanded hero rosters.
