The Weather Underground are a small band of radical environmentalists whose sole purpose is to bring down the financial empire of North Central Positronics. Depending on who you ask, they are terrorists or revolutionaries, but all agree that they are pirates. They fund their movement and stock their fleet by hijacking NCP cargo freighters, selling the cargo, and refitting the ships for battle. The Gunship Vendetta was an aging NCP cargo tug before being rebuilt as a fierce bird of war.
Cool, I think it is very well constructed, but a little uninspired in the aesthetics department (looks too much like every other ship of this scale). Otherwise I think its pretty good, especially your use of greebles.
