Mortal Kombat: Shaolin Monks is a 2005 action-adventure game developed and published by Midway for the PlayStation 2 and Xbox. A spin-off of the Mortal Kombat franchise, it is a retelling of the events of Mortal Kombat II (1993). Players control the eponymous Shaolin monks Liu Kang and Kung Lao in either single player or cooperative play as they protect Earthrealm from the forces of Outworld.

A spin-off centered on Liu Kang had been considered since the early 2000s, but was shelved after negative reception to the previous adventure spin-offs, Mythologies: Sub-Zero (1997) and Special Forces (2000). Shaolin Monks was officially announced in 2004 as part of Midway's plan to release Mortal Kombat games annually. Developed with the intent of appealing to Mortal Kombat fans, Shaolin Monks incorporates elements from the fighting game entries, including Fatalities, combos, and a versus mode.

Released in North America on September 19, 2005, the game received positive reviews for transitioning the series into an adventure game and its co-op mode, although reception to the narrative, visuals and short length were mixed. It was also a commercial success, selling over one million copies.

The game features three main modes of play. Aside from a single-player mode, the game has a co-operative mode, where two players can work together through the game, with access to some areas and items that are inaccessible in single-player mode. There is also a versus mode, where two players can fight against each other in some of the arenas featured in the game. In addition, players can play a shortened, censored demo version of The Suffering: Ties That Bind as well as an emulated arcade perfect version of Mortal Kombat II (which is taken from Midway Arcade Treasures 2; developed by Digital Eclipse).

Shaolin Monks features a multi-directional combat system, which gives players the ability to attack any of the enemies that surround them fluidly. The engine allows the player to maintain combo attacks across multiple enemies, and even continue their combos after launching an enemy into the air through a powerful attack or a throw. The main characters also have many of their signature moves from the series. Combos and special moves are upgradeable through the earning of experience points. These are mainly gained through defeating opponents, with the combo system multiplying the value. The environment plays a vital role in the game, as there are several hazards that will instantly kill an enemy, such as pits in the floor or rotating wheels of spikes. Using some of the environment in this manner, as well as attacking or destroying certain objects, serve as a puzzle-solving element to unlock secrets in the game.

The game also includes Fatalities, a common feature of the Mortal Kombat series. Performing combos on enemies increases the Fatality meter. Once that meter has reached a certain level, a Fatality may be performed, regardless of an opponent's level of health. The main characters have the ability to perform several different Fatality moves, some of which are 3D updated versions of Fatalities from the first and second Mortal Kombat games. The player can also unlock the ability to do Multalities, which are Fatalities performed on multiple enemies at once. The concept of Brutalities from Ultimate Mortal Kombat 3/Mortal Kombat Trilogy has also been brought back, though with a different function. Once the move has been performed, the player is able to give more devastating attacks for a limited time.

The primary protagonists of Shaolin Monks are Liu Kang and Kung Lao. Featured as allies of the protagonists are Raiden, Johnny Cage, Kitana, Sub-Zero, and Jax. Most of the allies make appearances to assist the protagonists during segments of the game. Depicted as enemies of the protagonists are Shao Kahn, Shang Tsung, Mileena, Jade, Reptile, Baraka, Goro, Scorpion, and Kintaro. These characters serve as bosses for the game's levels. Ermac and Kano can also be fought as optional bosses. Further characters featured are Sonya Blade, Kabal, Noob Saibot, and Quan Chi, who mostly only appear in cinematics. Smoke, in reference to his Mortal Kombat II depiction, is found in the Living Forest where he assigns the player optional missions required to unlock Mortal Kombat II. Also in reference to the second game, Blaze appears fighting his unnamed opponent in the background of the Pit II. Upon completing the game, Sub-Zero and Scorpion become unlocked as playable characters in the story mode, although the story is unchanged. The versus mode features Liu Kang, Kung Lao, Scorpion, Sub-Zero, Johnny Cage, Kitana, Reptile, and Baraka as the playable characters; all but Liu Kang and Kung Lao are unlocked through collecting tokens found in the story.

Mortal Kombat: Shaolin Monks spans the events of Mortal Kombat II, starting with the aftermath of the first Mortal Kombat. The battle rages furiously on Shang Tsung's island fortress in the Lost Sea, as the sorcerer watches the fighters battle his soldiers to protect Earthrealm. The Earthrealm's Shaolin monk Liu Kang defeats Shang Tsung, and the warrior Goro comes to his defense. With Goro distracting everyone else, Shang Tsung creates a portal to Outworld and retreats with his allies. Thunder god Raiden appears afterwards and warns the remaining fighters to get off the island palace because it is collapsing into the sea. Everyone, except Liu Kang and Kung Lao, evacuates and escape back to the Wu Shi Academy.
