About This Game

Traverse the sleeper coaches of an apparent empty Indian train—or so it seems. If you see an anomaly, face it and move forward. If not, it may be a trick of the mind—return to the previous coach. But beware, some anomalies will do everything to stop you. Face them or be lost forever.

Detailed Description

A game journey set on a cursed Indian train.

You were late. The train had already started moving. In a panic, you jumped onto the nearest coach—S0.

Your seat is in S9. But the train.... feels wrong.

Unnatural anomalies twist the space around you— missing objects, distorting memory, breaking reality. They want to stop you.

Observe carefully. Move forward only if you detect something off.
See nothing? Then something’s wrong. Turn back and go to the previous coach.

Make the wrong choice—and you’ll find yourself back at the start.

Don’t ignore the anomalies. Don’t trust your senses. Don’t turn around… unless you have to.

Meet me at S9.

An anomaly-hunting horror game inspired by Indian sleeper trains.
