Impostor Killer

Stalk the corridors as a ruthless imposter and cut down anyone who gets in your way — this one's pure, messy survival.

You're the imposter, and the crewmates don't stand a chance. Impostor Killer drops you into a compact map full of panicking little astronauts, and all you need to do is chase them down and tap space to swing. It's fast, brutal, and surprisingly satisfying. I kept coming back just to see how long I could chain kills without getting cornered by the angry mob that spawns in after you.

Arrow keys to move, Spacebar to attack, or use touch controls

Don't just hold space — time your swings. A missed attack leaves you open for a full second, which is plenty of time for a crewmate to escape. Watch for the red arrow. That's the armed survivor, and he'll chase you across the map. Kill him first or he'll break your streak. Circle around groups. If crewmates bunch together, attack from the side or behind — they scatter in straight lines, so you can cut off two or three at once. Use corners. The map has narrow corridors and crates; pushing enemies into a dead end means free kills without them slipping past you. On mobile, try tapping quickly instead of swiping. A double tap often lands the second hit before the crewmate regains control. Keep moving even after a kill. The screen shake can disorient you, so strafe immediately to avoid the next crewmate tackling your back.
