How many GB is The Backrooms: Mass Extinction?

22 GB

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

Leave at least 32 GB free: games need headroom to unpack updates.

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

If you noclip out of reality in the wrong areas, you'll end up in the Backrooms. The old moist carpet, the mono-yellow rooms and the hum-buzz of the fluorescent lights will be your only comfort in the endless purgatory you have found yourself in. Don't bother crying out for help. Nobody is left.
