Classic Game Room presents a CGR Undertow video game review of Teenage Mutant Ninja Turtles: The Hyperstone Heist for the Sega Genesis from Konami. Released around the same time as TMNT IV: Turtles in Time on the Super Nintendo, Hyperstone Heist utilizes the same core elements of the arcade classic, but sees a few slight tweaks including modified levels, increased difficulty, and graphical effects exclusive to the Sega version. But in the end, it's still Leonardo, Donatello, Raphael and Michaelangelo versus the Shredder, and Hyperstone Heist delivers plenty of great beat 'em up action. This review features Teenage Mutant Ninja Turtles: The Hyperstone Heist gameplay footage and commentary from CGR Undertow reviewer Kevin.
