While i can't decide between Horde mode, and Firefight, i would like to comment on...
Mad Moxxi Underdome Riot. FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
I have never played anything that hard. In my life. Ever. I take that back, "hard" isn't the word. "taxing" is more accurate. The 20 round gauntlet took me and my 2 friends 8 hours. We found safe zones in each level and survived purely on my regenerative ammo weapons. Swapping them out to each other whenever we were low. Even with our totally OP ability setups, GOD it took sooooooo looooooooooooooooooooooooooooooooooong.
It makes me cry myself to sleep at night.
