This mod has been laid to rest, possibly forever. :)
This is a video from execlent recent progress made by Drakklord on the weapon systems for Gunstar Heroes: Resurrection, (He also made the temp map too as a token of his extreme bordem one day :D, hes quite the handyman)
It shows all 4 of the single weapon discs and explains what they do and how.
people have been busy over the past year, so progress was crawling with broken arms at some points :D
