Classic Game Room presents a CGR Undertow video game review of Sonic the Hedgehog 2 for the Sega Genesis. In the first sequel to Sega's flagship series on the Sega Genesis, Sonic is joined by a new friend Tails in an all new quest to stop the evil Dr. Robotnik aka Eggman. The core gameplay elements are still there but this follow up features numerous improvements to make things even faster and flashier, including the new spin dash move, 2 player versus and cooperative modes, and some amazing graphics and memorable music. This review features Sonic the Hedgehog 2 gameplay footage and commentary from CGR Undertow reviewer Kevin.
