Bill has wandered into the backrooms - an endless maze of yellow wallpaper and stained carpet - wearing nothing but a hazmat suit and a lot of hope. Each floor hides a set of anomaly pieces and a glowing green portal, and somewhere in the gloom there are things that would rather Bill never left. Every monster you manage to escape is written into your compendium, so the deeper you go, the bigger your collection of nightmares. Looking for more liminal scares? Visit Backrooms and Backrooms Recovery.
Walk with WASD or the arrow keys (ZQSD also works), or drag on a touch screen. Pick up all the anomaly pieces shown on the skull counter, then head for the green portal. You have three hearts and no weapons, so when a creature spots you, turn and run - break its line of sight around a corner. Open the map to plan your route and the green book to read about the monsters you have survived.
