Mega Drive/Genesis changes
• Animalities and Mercies removed.
• Sonya's Friendship from Mortal Kombat 3 is used as opposed to her Friendship from the arcade version of UMK3.
• Brutalities introduced, a new form of Fatality which allows the player to attack their opponent with a series of kicks and punches which result in the victim exploding.
• Shao Kahn's treasure chest has only 10 boxes instead of 12.
• Sheeva has been removed.
• Kitana's Kiss of Death only inflates heads, the same effect as Kabal's air pump fatality.
• Rain and Noob Saibot are playable. Mileena, Ermac and Classic Sub-Zero are playable without any need of codes.
• Motaro and Shao Kahn are unlockable characters for two player fights, although only one player can choose a boss. In addition, only one boss can be unlocked at any given time.
• Shang Tsung can morph into Robot Smoke, which is not possible in the arcades. He can also morph into Noob Saibot and Rain.
• Announcer no longer announces the characters names.
• Most of the MK3 levels are missing which include the Balcony and Street so uppercutting in the Subway and Soul Chamber does not take you to level above.
