The zombie one is pretty good minus running around a lot. It has a good story and environment, also the new enemies are somewhat fun, I guess. The Mad Moxxy one totally sucks though, ugh, too damn hard, too long, no reward. I'm pumped for the new one, suppposed to raise the level cap and have a new vehicle and a bunch of new weapons and enemies.
So, I finally got the game and it's awesome ^-^ I picked Siren and it's going pretty smooth for now~ I also enable thrid person mode, here's tut how to do it http://gbxforums.gearboxsoftware.com/showthread.php?t=80533 Easy
Does Borderlands have DX9 Compatibility? DX10 on my Laptop can play it but its SUPER Laggy... My Laptop is a Dell Inspiron 1545 by the way...
