Ultimate Fighting Championship for the Game Boy Color brings the intensity of mixed martial arts to the portable console. Likely featuring a roster of fighters, each with unique moves and attributes, the gameplay focuses on head-to-head combat.  The simplified controls make it easy to pick up and play while maintaining the essence of UFC action.  The graphics and sound would have been tailored to the Game Boy Color's capabilities.
