This one is fun. Make good use of your arms and hop around for your close range missile cluster of death. Oh you get an LLas to encourage people to get closer. Not a true zombie, but fun enough. XL version included, not nearly as tough, but still really impressive with the additional speed.
My version, better cooling, and more jumpy. The extra JJ allows you to play with your big fat targets better, usually by jumping over them. Or this one if you want to do more (ER)LLas. This one is good for shooty warfare also. The +A version as suggested, I think this sucks though.
