How many GB is Backrooms: Lost Signal?

26 GB

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

Leave at least 37 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 terrifying 1-4 player co-op horror game. Explore 10+ handcrafted Backrooms maps, survive against 8+ unique entities, and use proximity voice chat to coordinate or panic. Your decisions shape the story with multiple endings. Discover optional lore that reveals the truth behind these Backrooms.
