DLC FAIL!
First off I just want to say that I really love playing Borderlands. Everything except Mad Moxxi's Underdome Riot. They really created a huge waste of money for fans of this game. The loot drops are not worth the effort and you receive zero experience.
Oh, but you get a bank. So you are literally buying a $10 bank for a game that if you already played through twice and have a level 50 character, what good is the bank at that point anyway? You've already sunk countless hours into the game while managing your inventory without a banking system. Why now?
But wait, you get two more experience points. Again, big deal. If you have a level 50 character, you can pretty much destroy anything in the game without too much of an issue.
Another horrible thing about this DLC pack is that it has achievements. So if you are like myself and have grabbed every single achievement this game has to offer along with the achievements from Dr. Ned's, you will be incredibly disappointed with Mad Moxxi's achievements. Why? Because they are not fun at all to obtain. So far the worst achievement in the game was the brain collecting one for Dr. Ned's Zombie Island. Not anymore.
In Mad Moxxi, imagine trying to obtain the zombie brain achievement over and over again only this time it will take you much longer and its much harder as the rounds progress. Do yourself a favor and just farm these. That way you can keep your "S" ranking for this game and never have to go back to the DLC unless you want to use the bank.
I really hope the next piece of DLC makes up for the epic failure that is Mad Moxxi's Underdome Riot.
