Deadly Alliance
"Mortal Kombat: Deadly Alliance" features a roster of 21 characters, 10 of them unlockable. This game allows characters to move in 3-D space by sidestepping into the foreground or into the background. Each character has three fighting styles available to them: two hand-to-hand styles and one weapon style. You switch between them at will with the "L1" button--all characters have at least one combo that utilizes all three styles.
According to GameFAQs, "Mortal Kombat: Deadly Alliance" to date remains the only game in the series not to feature the main character Liu Kang in the roster; in the opening cutscene, the villains Shang Tsung and Quan Chi kill him.
Deception
"Mortal Kombat: Deception" has more characters and several new game play modes, such as Kombat Chess, a fusion of chess and the classic "Mortal Kombat" style of fighting. Midway, maker of "Mortal Kombat," increased environmental interaction in "Mortal Kombat: Deception." By maneuvering your opponent to certain areas in a stage, you can either take the fight to a different part of the stage or end the round immediately with a stage fatality, in which your opponent meets a gruesome end via deathtraps. "Mortal Kombat: Deception" introduces Konquest, an adventure mode in which you travel through the realms as Shujinko to gather the artifacts necessary to defeat the Dragon King Onaga.
Mortal Kombat: Shaolin Monks
"Mortal Kombat: Shaolin Monks" departs from the typical fighting game approach. The game's plot takes place between the original "Mortal Kombat" and "Mortal Kombat II." It plays like a 3-D action game, allowing you to move your character through a stage. According to GameFAQs, you can play through the main storyline as either Liu Kang or Kung Lao, but can unlock Scorpion and Sub-Zero later. Other characters playable in Versus mode include Kitana, Baraka and Johnny Cage.
Mortal Kombat: Armageddon
"Mortal Kombat: Armageddon" ends the PS2 series of games. Every character that has ever appeared in a "Mortal Kombat" game as a fighter or a cameo character appears in this game; all 63 fighters show on the character select screen. Because of the number of characters, the game removes one fighting style, allowing one weapon style and one hand-to-hand style. You can also perform aerial combos.
"Mortal Kombat: Armageddon" has a character creation option. After creating a player profile, you can customize a male or female character's appearance, weapons and fighting styles. In addition, you can give created characters a victory phrase and biography for use in online play.
