Radical Rex is a side-scrolling platformer that borrows elements from Adventure Island and Sonic the Hedgehog. Beam Software developed the game for the SNES, Genesis and Sega CD. Rex can disable enemies with his roar and firebreath, as well as use skateboards and other tools.
The goal of the game is to rescue other dinosaurs affected by the spells of Sethron, a malevolent human shaman. In the two Sega versions, Sethron is replaced with a mammalian creature named Scritch.
