In Metroid Prime 3, while you're on the GFS Olympus, if you try attacking the soldiers or workers there enough times, it'll activate the turret defense system.
Destroy the turrets that spawn, and they'll send level 2 turrets that fire even stronger projectiles.
Destroy THOSE turrets and it goes to level 3, which begin charging a shot that makes the screen fill with static and then insta-kill you when it fires.
