Well, I did a little checking and was greatly surprised at what set I got it with; I remember the set fondly: http://www.peeron.com/inv/sets/1682-1
This being said, I'm trying to work out the barrel(s?) of the gun so that it looks excessive without being completely overweight.
Alright, got it. I present to you the ZNAFU II Pestilence Variant.
This beast can barely stand up now. I sure hope you're happy IV.
Edit: I think I may have figured out how CP works. Hopefully. Feel free to correct me.
