INTERFECTOR.

Trust no one.

The Killer party game, digitalised for your nights out.

Interfector app icon

Interfector turns any party into a game of Killer. Every player gets a secret target and an absurd mission to pull off in real life. Mission accomplished, the victim confesses, the killer inherits their target. Last one standing wins.

One target

Assigned secretly by the app. Nobody else knows who's after who.

One mission

Absurd, playable in real life. A single witness is enough to confirm.

One survivor

The chain tightens, alliances break, one player takes it all.

Interfector — the Killer game

An identity with an edge.

A name, a logo, a tone. The app owns its dark humour from second one: hood, silence, one clear promise — trust no one.

Interfector splash — Trust no one.
Your mission awaits

A secret target. An absurd mission.

The mission screen fits on a single card: your target, their bio, the mission to run, one button — I completed my mission. Get suspected? Report it in one tap.

The golden rule

Your victim confesses. You inherit their target.

The confession triggers everything: the victim confirms in-app, your counter ticks up, the app reveals your next target. The chain tightens live.

Ready in 30 seconds

Onboard your friends in one tap.

A code to shout across the room, a quick share, and the list of future victims fills up. Up to 30 players, one host, zero friction.

All the way

The last survivor wins.

End of game: the app counts eliminations, hands out silly trophies — sneakiest player, dumbest death, shortest survival — and offers to run another round on the spot.
