Defeat the Slave Driver (Any Difficulty)
Near the end of Chapter 7 “Edge of the World,” at the “Stray Dogs” checkpoint, you will face off against the Slave Driver. When fighting him there will be a ton of slaves that come charging out, so keep on your toes and don’t stop moving. When the Slave Driver’s shield drops, hit him with either a High or Low Grav blast and then go to town on him for the few seconds when he is immobile. Once he is up and active and sets his shield up, continue to run, killing slaves that get in your way. Eventually, when you have plugged the Slave Driver enough, he will drop and you will get this well-earned reward for a tough fight.
