So, after playing this game some, I found some glitches. On the space map, the laser fires when the game is paused, making it possible to stop getting killed by it and kill with it. The second is with the Sniper, and when the Overkill passive skill is equipped and an enemy is shot with a headshot with a great sniper, the next shot will insta-kill. This keeps looping, so you can insta-kill five times in a row before the damage catches up with itself.
