Deadlift is an enemy in Borderlands: The Pre-Sequel
This is the first full on Boss that you need to deal with. Deadlift is a crazed Scav in a really cool spacesuit. The area has a lot of height to it so feel free to use all the Jump Pads. They are the best way to get out of a tight spot here.
Deadlift has a number of attacks. The hardest one to deal with is his ability to electrify sections of the floor throughout this area. If you land on them, then you will take constant shock damage until you jump off them. He is also able to launch homing balls of shock energy at you as well.
The good news to Deadlift is that he is very slow. If he isn't getting around using the Jump Pads that is. This makes dealing with him at a distance very easy.
The best way to deal with Deadlift is to snipe him. Distance is your best friend. His weak points are the massive tank on his back and his head. Just aim for either with a Sniper Rifle and blast away from a distance. Because of his low speed, it isn't too hard to get a lot of damage in.
