Betrayal.io

Betrayal.io is a multiplayer murder mystery where players take on Crewmate, Betrayer, Sheriff, or Jester roles. Crewmates complete tasks and stay vigilant while Betrayers sabotage and eliminate. After rounds, players discuss clues and vote on who to eject—the wrong choice helps the betrayers win.

Choose from maps like Spaceship and Haunted Mansion, try modes such as Core and Hide & Seek, and relax in a dedicated fishing lobby. Personalize your character with outfits, skins, and pets, and enjoy frequent updates with new maps, modes, and cosmetics. Join the Discord for announcements and feedback.
