I'm not realy sure why the main character is a zombie. I haven't played too far in, but all of your powers are class-based. As far as I can tell, none of them have to do with being a zombie. It seems like a plot device that's dropped early on and then forgotten.
The dialogue and story could use some work. You're wandering around because you have nothing else to do. Veradux teams up because... he does.
But still, it's a fun equipment-based RPG. Pretty standard stuff.
