How many GB is Infested Fortress?

5 GB

Leave at least 11 GB free: games need headroom to unpack updates.

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

Dig into the mountain, collect resources to build your fortress, grow your population and keep them alive (and happy), learn new deadly skills, gather and refine materials to craft powerful items so you can fend off the many dangerous monsters threatening your colony in turn-based tactical combat.
