Ultraverse Prime — About this game
Thirteen-year-old Kevin Green becomes the powerful Prime when his girlfriend Kelly disappears. The Sega CD adventure starts in the streets and moves through sewers and the sky, using punches, kicks, jumps and grapples to break through enemies. Objects can become thrown weapons, while flight sections change the pace. The disc also offers Comic pages and Malibu Video interviews, letting you explore the hero’s comic origins outside the fighting mode.
