A Sega coin-op which was converted to several platforms including the Megadrive, Master System and Commodore Amiga. Effectively a sci-fi themed variant of Golden Axe, with three player simulataneous play and scrolling beat-'em-up levels interspersed with first-person Operation Wolf style shooting levels. The original version was made for the System 16 arcade board, and featured rudimentary scaling effects. The artwork, music and sampled sound is similar to that in Golden Axe and the Megadrive game Sword of Vermillion, as all three were developed by the (roughly) the same team - AM1.
