Psychological anomaly horror set in an abandoned school corridor. Find what has changed and make the right choice. But even the right choice doesn't guarantee escape. The corridor won't let you leave that easily.
The corridor feels normal.
Until you begin to doubt it.
Corridor 13 is a psychological anomaly horror game set in an abandoned school hallway that can change with every loop. Your perception determines whether you move forward — but the right decision alone does not guarantee escape.
Observe. Decide. Survive.
With every run, the corridor may have changed.
Sometimes noticeably. Sometimes barely at all. Sometimes not at all.
Your task is simple:
If everything seems normal → move forward.
If something feels different → turn around.
But once you've identified an anomaly, the most dangerous part begins.
The way back is not always clear.
Some anomalies block your path.
Others react to your presence.
And some do not want you to make it out alive.
Make twelve correct decisions in a row to reach Corridor 13.
One wrong step — and everything begins again.
Or ends where you thought you were safe.
