Counter Strike Online Wiki

Mobius (fun_suddendeath) is a Sudden Death map in Counter-Strike Online.


  • Kill everyone around and reach the first victory condition.
  • Bonus points are given by surviving and killing enemies.
  • All players start mostly at the same distance no matter where, so everybody could get the dropped weapon. This is true since each level is designed symmetrically.
  • Falling off the map will result in death.
