Spectrum of Violence is a 2D fighting game created in Flash by Joseph King and R. Hunter Gough. It took us several years to make it, working on it off and on along with various other projects. It's still very rough around the edges, but we wanted to go ahead and release it even in an unfinished form so that other people could enjoy it.
