SteamAbout Backrooms Anomaly Project

You are trapped in the Backrooms.
A seemingly endless corridor stretches ahead, but something is always changing. Study your surroundings, spot anomalies, and decide whether it is safe to keep moving.

Spot the Anomalies
Look closely. A light might flicker differently. A door might disappear. A familiar object might move. Something in the distance might not have been there before.
Not every anomaly is obvious. Some changes are subtle. Others are waiting for you to get close.

Know When to Turn Back
Think you spotted something wrong? Turn around and retrace your steps.
Everything normal? Keep moving forward.
Make the wrong call and you may have to start again.

Something Is Watching
Not every anomaly can be solved by simply turning around.
Dark corridors, strange sounds, and things that should not be there can turn a quiet walk into a desperate run. When something starts chasing you, don't stop.

Reach the End
Progress through a series of increasingly unsettling sections as you search for a way out.
Observe. Decide. Move forward.
Or turn back.
But whatever you do, don't assume the corridor is still the same.
