Great zombies DLC with a great story. You've never killed so many zombies with so many different weapons.
Presentation: More story than Borderlands itself but still very little story; not important because it's just plain fun.
Gameplay: Just like you'd expect, killing zombies is easy, just aim for the head and they die easily; anywhere else and you may as well just stand still and not waste your ammo. There's a lot of different zombies ranging from standard zombies to zombies in Crimson Lance armor.
Graphics: Hideousness has never looked so appealing and Wereskags look especially frightening.
Sound: The sound of a zombie puking makes you want to puke, in a good way. Zombies sound real most of the time and a Wereskag howl will make you jump.
Lasting Appeal: Beat it once with every character, and beat it again in playthrough 2 with every character because it's just that fun.
