How many GB is Prison Alone?

3 GB

That is more than the typical Platform game, which needs about 2 GB.

Leave at least 9 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 psychological horror game with NO jumpscares. Feel the tension and suspense, get goosebumps, experience strange frightening events, and explore, look for keys, solve puzzles, while thinking hard to find a way to get out of this huge, and maybe not so empty prison.
