How many GB is Backrooms Lost Runners?

6 GB

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

Leave at least 13 GB free: games need headroom to unpack updates.

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

Backrooms: Lost Runners is a co-op survival horror game where teamwork, voice-reactive AI, and immersive puzzles merge. Explore unsettling liminal spaces, outsmart cunning entities, and dive into a deeply interactive story—remember, even your whispers can betray you.
