Mirror Backrooms

A FIRST-PERSON HORROR GAME ABOUT LOOKING TOO CLOSELY.

You fall into the Mirror Backrooms. Two corridors move with you, and they are identical—until a chair shifts, a light turns the wrong colour, or a figure is standing where nobody remembers seeing one.

You have no weapon. Your only tool is a sonic ring that marks an anomaly and nothing else. Fire it at the wrong thing and the sound carries: the nearest Crawler wakes up, and it knows where you are standing.

This is a game best played in a dark room with headphones on. Uncanny, quiet, and then suddenly not quiet at all.

MORE THAN 100 CRAWLERS. NONE OF THEM SHARE A RULE.

Some follow footsteps. Some wake when you run. Some move only while nobody is watching—and the moment you turn back to compare the two corridors, you have stopped watching.

Others reach through the mirror while you are still deciding whether the room is wrong. You cannot fight any of them. You can only be somewhere else.

EVERY ROOM CHANGES WHAT YOU ARE ALLOWED TO TRUST.

Room laws rewrite darkness, direction, distance, time, the mirrored views, even the behaviour of the tool in your hands. A habit that kept you alive in one room is the trap waiting in the next.

You will learn quickly, hesitate often, and keep asking the same question: is the room wrong, or is my memory?

BEING WRONG TOGETHER IS WORSE.

Play alone, or with up to three friends. Split up to check different angles, compare what each person remembers, and decide when the evidence is enough.

"Was that table there before?" "Don't fire yet." "Did that thing move?" One teammate may catch what everyone missed—or sound so certain that the whole team walks past it together, and hears something wake up behind them.

NO TWO RUNS STAY FAMILIAR.

100 named floors, 1,000 numbered rooms and more than 2.1 billion seeds recombine spaces, furniture, lighting, anomalies, room laws and Crawlers. Weekly challenges drop every player into the same sequence, with Steam leaderboards recording who saw more clearly and got deeper before something caught them.

Find the anomalies. Repair them. Make both sides identical again. The deeper you go, the less you want to know what "identical" means down here.
