CUW's are going to be weapons specifically crafted and designed for an individual. currently, every developer is being given the opportunity to create, or have a weapon created according to whatever they desire in TMJ. perhaps hull will allow more CUW's to be rarely given to the general public as a reward or something. i havnt asked him yet. My weapon is a limit breaker, "Silver Soul-Eater" and gains +1atk for every kill. several other developers have theirs in the making. you should post a comment just in case on a weapon that you would like. might give the weapon dev's some ideas.
I'm working on my CUW. It will be epical. I'll post it up on Facebook when its ready. Then, Matt, please copy it to the dev for me. I can't upload nothing on there due to the lack of a computer. You might have to do that for all my concept art... are you up to help your Ginger? :p
