How many GB is Outbreak Overlord?

0.68 GB

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

Leave at least 6 GB free: games need headroom to unpack updates.

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

Turn the entire population into zombies before your horde is exterminated. Be strategic in your attacks and become the apocalypse itself.
