If you played the origional Gunstar heroes on Sega Genesis, then you know what this game is all about and probably already picked this port up. If not I Highly suggest you try this demo out. You play as one of the two "Gunstar twins" whose older brother green was kidnapped by the empire and is using him via mind control to find four crystals in hopes of reviving the legendary "Golden silver", in order to use it's power for world domination. As one of the twins you set out on a quest to get the crystals before the Empire does and hopefully free your older brother from their evil grasp.
