Moxxie DLC sucks. For those who haven't played it, it is broken down into maps, rounds, and waves:
-There are three maps (don't remember the names) with two modes (5 round and 20 round).
-Each round consists of five waves:
1) Starter (assorted basic enemies)
2) Gun (bandits and lancers)
3) Horde (midget, burning, normal, and badass psychos)
4) BadAss (BadAss level enemies make an appearance here on later rounds but up to four, generally not)
5) Boss (rematch a previous boss with a few accompanying goons or, in the case of Nine Toes, Skags)
That's all fine and dandy. There are four problems though:
1) It gets very, very boring having to do the same crap over and over and over 25 + 25 + 25 + 100 + 100 + 100 + ? times. That's right, at bare minimum, you're going to see the those waves cycle at least 375 times. Ridiculous, right?
2) If you (and all your companions) die, you'd think you would just restart your current wave, right? Wrong. Well then, restart the group? Wrong. You restart at the last group at the beginning. For example, you are on Round 5, Wave 5 (Boss) and you all die. Instead of starting at Wave 5 or Round 5, you start at Round 4, Wave 1 (Starter). That means you not only have to replay all the progress you made on your original group but you also have to replay the last group. It makes no sense what-so-ever. If that wasn't bad enough, it gets worse...
3) There is no saving, at any point, during these rounds. If you lose power, you are back to Round 1, Wave 1. If your co-players have to leave during this tournament and you exit to the Underdome, you are back to Round 1, Wave 1. If it is past your bed time and you have to stop, you are back to Round 1, Wave 1. In other words, if you want to finish one of the tournaments (5 or 20 rounds) you have to do it all in one go--there is no stopping and coming back to it: plan a whole day.
4) The loot/rewards hardly justify pumping so much time in to it. It's almost like they want you to never finish it--just keep playing to pick up the few goodies at the end. Well, reality check, you can get more, better loot just by playing the game and not messing with Moxxie at all. Not to mention, my level 50 character only has 39 backpack slots but, at bare minimum, you will encounter no less than 60 goods to pick up during the 20 round event. There is no way for a single character to hold them all and no way to unload those you do have.
I would not recommend buying this DLC. It is beyond ridiculous--approaching insanity. Only the bank is really useful (with purchase of an upgrade, it will hold 39 items for me--matches inventory count).
