Borderlands – continue an old campaign with a new character

Dueling lets you test your muscle against your fellow players. For the most part, it is for fun. Especially since it isn't balanced very well. Some classes are better at dueling than others, and your character and item levels have huge affects on the outcome.

There is a Badass Challenge called "Haters Gonna Hate" that rewards you for duel wins. The max rank for the Challenge is after 50 wins. You get the first level for winning your first duel, next rank for winning 5, and so on, up to 50.

There is no penalty for losing. After a duel your shields and health are restored for the most part. Though any ammo you used during the duel is lost, and special power timers and other timers used are not instantly reset but have to going through their usual time to refill. But all of that is easily recovered with a little bit of time and opening of boxes.

The Wiki says there are 5 new weapons introduced in the DLC. There are four new Uniques (blue): The Cobra, The Pocket Rocket, The Boom Puppy, and The Kitten, as well as a new E-Tech shotgun called the Slow Hand. There are no new Legendaries sadly. All of the orange Tourgue weapons in the vending machines can be found as possible drops in the general campaign.
