Betrayal.io is a multiplayer social allowance game like Among Us. You play the game as a crew member or a mysterious saboteur called a "traitor". The traitor must undermine the tasks, while the crew members must complete their duties without being slaughtered. Crews must complete all missions without being killed. In case you suspect who the cheater is, you can consider gathering and holding a vote to show them off. Double crossovers can break drills and break free from their teammates. There are openings that allow double cross machines to move in undetected. Kill all crew members to dominate the match as a double cross. You can play Betrayal.io in online public games or in private hangouts with companions. Tracking a record allows you to save your name and progress. There is also extensive character customization with clothes, hairstyles and pets!
