Static Defender is an achievement that requires you to kill 500 enemies with deployable Sentry Guns.


  • Any type of sentry gun will give credit for this achievement - the Bullet Sentry, the Freeze Sentry, the Incendiary Sentry, or the Explosive Sentry.
  • The elevator section of the Cargo Elevator level is a great place to set up a sentry gun and watch the kills roll in. You can have the sentry cover as much of the elevator itself, or turn it to face the slope behind the elevator so it takes out the Drones that try to climb up.
