How many GB is Operation: Outbreak Idle?

1 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

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

Command automated military defenses, upgrade your fortress, and survive massive zombie waves in this action-packed idle defense game. Build powerful defenses, unlock upgrades, and hold the line against endless undead hordes.
