Sector 404

In Sector 404, you play as a man returning home late at night. After taking his medicine as usual, he finds the quiet block unsettling: the stairwell seems endless, the air feels heavy and unseen eyes appear to follow him. Your goal is to reach your apartment, but the building stands in your way.

Reach your apartment

Starting on the ground floor, choose a route of 10, 15 or 20 floors. Longer routes bring more chances for something to go wrong. Watch the floors for anomalies by paying attention to shadows, sounds and small details. Miss one, and you are sent back to the start.

Find the anomalies

The block contains 80 unique anomalies, so each game can differ. You have an old phone that shows how many anomalies have been detected in the building, though not necessarily found, and an electronic anomaly detector. Wave the detector near radios, TVs, computers or phones; faster beeping and rising numbers indicate something unnatural nearby.

As you make your way through the building, you may wonder whether the things you see are familiar because you have already made it home—and this is what home looks like now.
