How many GB is The Alien Cube?

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.

A disturbing reality is about to be unveiled, something that mankind should never know. After a mysterious finding, unexplainable facts occur and strange happenings will lead you to doubt the world around you. Uncover an otherworldly secret and explore forbidden places to find out the truth.
