Clear Firing is an achievement that requires you to kill 25 Drones without causing damage to other marines through friendly fire.


  • Despite the ambiguous wording, this achievement is a personal one: this means that as long as you don't cause friendly fire, you can earn it.
  • An easy way to earn this achievement is to use the Tesla Cannon, which does not cause friendly fire.
