How many GB is BunkerZ?

60 GB

That is more than the typical Strategy game, which needs about 3 GB.

Leave at least 77 GB free: games need headroom to unpack updates.

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

Stylized WWI trenches meet explosive co-op mayhem. Hold the bunker as a Rifleman, Medic, Engineer, or Machine Gunner. Fight back with era specific WWI weapons, shovels, and flamethrowers, then launch undead sky-high with grenades and explosives. Solo or multiplayer survival at its most chaotic.
