[quote name='Rodimus']Is all this DLC worth buying if I'm still on my first playthrough? (Siren lvl 19) Will it benefit me at all now or should I tackle them once I've completed the game?[/QUOTE]
I recommend you to tackle them once you complete the main quest. You're probably going to have a hard time if you get the DLC now. Also, from what I've seen with the Moxxi DLC, it's best to wait for that until a higher level.
I downloaded the Moxxi DLC earlier today and was able to get my friend to play co-op with me. Going from a recent interview, it looks like there are 20 round, 5 wave matches (100 total waves) which I think is way too excessive. 5 round matches typically takes about an hour to complete. I really cannot see myself playing 3-5 hours straight to beat a certain tournament.
There are different waves (Starter, Horde, Gun, Badass, and Boss). Horde is probably the easiest since you can simply run-and-gun without worrying too much for cover. The boss wave will consist of a boss you've already fought along with a couple of enemies. From what I've played, I didn't find them to be too hard as you're mainly focusing on one guy. As stated earlier, there are 5 waves per round, each round taking about 10-15 minutes depending on how long it takes to rid of the wave. There are three maps (I was only able to play one of them).
Co-op is highly encouraged. If a teammate ever dies in battle, they are sent up to a tower in the middle of the map and are able to use their skill and attack enemies below. They are to stay there until the wave is over. I found this to be effective with the soldier, as I was able to use my turret and heal my ally by shooting him.
After each wave, supply drops of health and ammo will magically fall from the sky. MEGA potions and MEGA ammo usually will supply you enough to reach max health. After a couple of waves, you will be able to collect loot at a certain location. I'm level 50, so I was able to get some rare weapons.
You will get modifiers in each wave. These modifiers may range from higher fire damage to better accuracy. It's randomly generated each round.
One complaint I have about this DLC would be the penalty for the death of the whole party. If your team were to ever be wiped out, you'd be sent back to the beginning of the previous round. So if you were on round 3, wave 5 and die, you'd be sent back to round 2, wave 1. I understand they were trying to make the game harder and more challenging, but it just avoids the inevitable and is unnecessary when you've already gone through the round. I understand modes like Firefight or Horde Mode have an immediate game over once you die, but it's something about Moxxi which makes it different...I don't know what it is.
The lobby will have vending machines, selling you ammo, guns, health, and etc. One new addition would be the bank, or storage system. You start out with 12 spots to hold your guns and equipment, and you may increase the size of the storage by paying a fee.
Overall, I'm satisfied with the purchase. The atmosphere of the arena is spot-on and Moxxi will rile you up throughout, making it you feel like your in a true arena.
I'm also looking for other level 50 Borderlanders who would like to play some Moxxi!
