Ultimate Mortal Kombat 3 is a fighting game in the Mortal Kombat series, released in arcades and later ported to the Super Nintendo. It is an update of Mortal Kombat 3 and later received its own update in the form of the Mortal Kombat Trilogy. Other Ocean Interactive later ported the title to the Nintendo DS in 2007, adding Puzzle Kombat from Mortal Kombat: Deception.
Two new gameplay modes have been introduced since the original Mortal Kombat 3: the 2-on-2 mode which was similar to an Endurance match but with as many as three human players in a given round on both sides (these had not been seen in the series since the first Mortal Kombat), and a new eight-player Tournament mode. An extra Master difficulty is present. Shao Kahn's Lost Treasures – selectable prizes, of which some are extra fights and others lead to various cutscenes or other things – are introduced after either the main game or the eight-player Tournament are completed.
To balance the gameplay, some characters were given new moves and some existing moves were altered. Some characters were given extra combos and some combos were made to cause less damage. Chain combos could be started by using a jump punch (vertical or angled) or a vertical jump kick, which creates more opportunities to use combos. Combos that knock opponents in the air no longer send one's opponent to the level above in multi layered levels; only regular uppercuts do this.
The computer-controlled opponent AI was improved in the game. However, three new flaws were introduced along with the revisions: while backflipping away from an opponent, if the player performs a jump kick, the AI character will always throw a projectile; this leaves the computer character vulnerable to some attacks and can easily lead into a devastating combo. If the player walks back-and-forth within a certain range of the AI character, the opponent will mimic the player's walking movements for the whole round and never attack. If the computer opponent is cornered, the player can repeatedly perform punches without the AI character stumbling back, thus allowing the player to win easily.
