How many GB is Doomsday Cave?

2 GB

Leave at least 8 GB free: games need headroom to unpack updates.

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

This is the post-nuclear war post-apocalyptic underworld as the background of the horizontal action survival game, you have to constantly collect resources to maintain their own and their family's survival consumption.
