Gunstar Heroes review. Classic Game Room presents a CGRundertow review of Gunstar Heroes, developed by Treasure and published by Sega. In a run-and-gun legend that put Japanese production company Treasure on the console map, Gunstar Heroes is a white-knuckle, full-speed-ahead shooter that might look like it belongs in arcades, but is a Sega publication that has earned its stripes. Defend Planet Gunstar 9 against an attacking Imperial menace with the twin brothers Red and Blue, along with a wide array of weapons and either fixed or freeform shooting. This video review features video gameplay footage of Gunstar Heroes and audio commentary from Classic Game Room's Eric.
