Killer.io

A Halloween party, a crowd of unsuspecting guests, and one cold objective — Killer.io drops you into a social deduction-style arena where blending in matters just as much as the kill itself. The challenge isn't simply eliminating targets; it's doing so without a single witness noticing something is wrong.

Bodies need to be dragged out of sight before anyone stumbles across them. Timing, positioning, and patience determine whether you walk away with a high score or get exposed in front of the entire crowd. The tension of acting natural while committing something far from it gives the game a genuinely unsettling edge.

Halloween decorations and a chaotic party atmosphere create the perfect backdrop for suspicion and misdirection. Other players are hunting too, which means nowhere feels completely safe. Whether you're methodical or opportunistic, the game rewards players who can read a room — and vanish from it just as quickly.
