Killer.io is a stealth-based multiplayer game where you take the role of a masked killer trying to eliminate partygoers without drawing attention. You must move through a crowded Halloween party, hide bodies in dumpsters, avoid being spotted by witnesses, and compete against other killers for the highest body count. Timing your strikes, blending into the crowd, and finding isolated targets are key if you want to outscore your rivals and stay undetected.
