Mortal Kombat: Deadly Alliance is a fighting video game developed and published by Midway for the Nintendo GameCube and Game Boy Advance. It was the first all-new Mortal Kombat fighting game produced exclusively for home consoles, with no preceding arcade release. Deadly Alliance is chronologically the fifth main game in the Mortal Kombat series.
While fleeing from Scorpion in the pits of the Netherrealm, Quan Chi discovers an ancient tomb which contains the remains of the mummified bodies of the army of the Dragon King, the first emperor of Outworld. Learning that the army is invincible and undefeated while resurrected, he realizes that he must find a way to implant warrior souls to fully resurrect the army. Therefore, he proposes an alliance with the evil Shang Tsung where his part of the deal will be immortality if he agrees to help him in his quest.
Shang Tsung accepts the deal and the Deadly Alliance is born. However before they could begin a total domination of the realms, the two sorcerers decide to destroy the only two beings that could prevent their goal of absolute conquest. The first was Shao Kahn, the Emperor of Outworld, who was murdered by the two sorcerers after they had made a false show of allegiance. They then traveled to Earthrealm by means of a powerful mystic portal known only to sorcerers and deities, and attacked the undisputed and reigning champion of Mortal Kombat: Liu Kang. Though Tsung was clearly losing the battle, Quan Chi's interference assisted Shang Tsung in gaining the upper hand. Because of this, Tsung accomplished a goal that he had set out since his defeat at the hands of Liu Kang in Mortal Kombat...
Liu Kang has finally fallen.
After consuming his soul, they returned to Outworld, where the souls of defeated warriors are used to resurrect the army of the Dragon King. Should they succeed, they will be fully unstoppable. Meanwhile in Earthrealm, another alliance is being formed - Raiden and Earthrealm's greatest warriors have reunited to kombat this new evil alliance...or die trying.
