Sector 404

In Sector 404, you play as a man returning home late at night. The block is quiet—too quiet. You take your medicine like always, but something’s wrong. The stairwell feels endless, the air feels heavy and unseen eyes seem to follow your every step. You need to get home. But the building has other plans.

Starting at the ground floor, your goal is simple: reach your apartment—but how far is it tonight? Choose your route: 10, 15, or 20 floors. The higher you go, the more chances for something to go wrong.

The floors hide anomalies - you must watch every shadow, listen to every sound, and notice the smallest things. Miss them, and you’re pulled back to the start. Again. And again.

With 80 unique anomalies scattered throughout the block, no two games are ever the same. Stay sharp - your survival depends on it.

To make it home, you’ll need every tool you’re given: an old phone that shows how many anomalies have been detected in the building—but not necessarily found. And an electronic anomaly detector. Wave it near radios, TVs, computers, or phones, and if it starts beeping faster and the numbers spike, you’ve found something… unnatural.

You’re not sure what’s worse - the things you’re seeing, or the feeling that you’ve seen them before. What if you’ve already made it home - and this is what it looks like now?
