How many GB is Outlast?

5 GB

That makes it bigger than 63% of Adventure games we have measured.

The median Adventure game needs 3 GB; the largest tenth start at 25 GB.

Leave at least 11 GB free: games need headroom to unpack updates.

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

Hell is an experiment you can't survive in Outlast, a first-person survival horror game developed by veterans of some of the biggest game franchises in history. As investigative journalist Miles Upshur, explore Mount Massive Asylum and try to survive long enough to discover its terrible secret... if you dare.
