How many GB is Mirror Backrooms?

4 GB

That is more than the typical Puzzle game, which needs about 3 GB.

Leave at least 10 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 first-person psychological horror game about looking too closely. Two mirrored corridors move with you and appear identical, but one of them is always wrong: a chair has shifted, a light burns the wrong colour, a figure stands where nobody remembers one. The player carries no weapon, only a sonic ring that marks an anomaly. Firing it at the wrong thing carries sound through the floor and wakes the nearest Crawler, which then knows where the player is standing. Over 100 Crawlers inhabit these floors and no two of them share a rule, and room laws rewrite darkness, direction, distance, time and the mirrored views themselves. 100 named floors and 1,000 procedurally recombined rooms can be played alone or online with up to three other players.
