How many GB is Quarantine Zombies?

20 GB

That is more than the typical Simulator game, which needs about 4 GB.

Leave at least 29 GB free: games need headroom to unpack updates.

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

Inspect survivors in Chicago's Quarantine Zone to spot the infected before they turn. No base-building - just tense inspections and gunfights! You've got 30 days until the army arrives. Hold out, fix your car, and fight your way through Chicago to the main checkpoint to save your little brother.
