About Sector 404
In Sector 404, you play as a dude just trying to get home late at night. But the block feels way too quiet. You pop your meds like usual, but something’s off. The stairwell feels endless, the air is heavy, and it’s like unseen eyes are tracking every step. You need to make it back… but the building has other plans.
Your goal sounds simple: start from the ground floor and reach your apartment. But tonight? Who knows how far it is—10, 15, maybe even 20 floors. And the higher you climb, the more things start to go seriously wrong.
Every floor hides anomalies. You gotta watch the shadows, pay attention to sounds, and notice even the smallest changes. Miss one, and boom—you’re dragged back to the start. Over and over again.
There are over 80 unique anomalies scattered in the block, which means no two runs ever feel the same. You’ll need to stay sharp—your survival depends on it.
The only tools you’ve got are an old phone that shows how many anomalies exist in the building, and an anomaly detector. Wave it near TVs, radios, computers, or phones—if it starts beeping faster and the numbers spike, congrats, you just found something unnatural.
But the real question is… what’s worse? The monsters you’re seeing in the building, or that feeling that you’ve seen them before? Maybe you’ve already made it home—and this is what home looks like now.
