High damage weapons are fun to use once you almost finish the game. You go back after you'e already cleaned out an area(which was a challenge b4), and then you just go god-mode and obliterate anything in your path! That kind of stuff is always fun after the fact.
OK I just got ahead of myself and was attacking lvl 27 stuff at 26 and got shredded. For the first time I got red drops I can't use yet too. Little bit more and I'm there but I found a nice spike in difficulty.
You need to look at the tip jar....there should be an X to talk and Y to tip option when you look at it. I needed to tip her close to $14k before she gave me a weapon.
I was tipping her last night to get the first weapon, she does the "well you deserve something back for that" line.. Starts like she is going to hand me a gun, then that idiot guy in moxxi's started talking and it ended her animation and talk. Does she just hand you the weapon?
