How many GB is Mama's Sleeping Angels?

10 GB

That is more than the typical Adventure game, which needs about 5 GB.

Leave at least 17 GB free: games need headroom to unpack updates.

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

Kiss and decapitate your friends in a Co-Op horror game about collecting cursed objects to feed to a deity called Mama, lest she hunger for you. Work together, and betray each other... Anything to keep Mama happy.
