In the story explored in Konquest mode, a young man named Shujinko is deceived into spending his entire life collecting the Kamidogu for Onaga, who uses the guise of an emissary of the Elder Gods, the beings who created the realms, named Damashi. Other enemies include the former defenders from the realms, who were resurrected by Onaga and are under his control. The latter include the forces of Edenia, now led by Mileena in the titular theme of deception as she masquerades as her sister, Princess Kitana. Those fighters who survive the battle against the Deadly Alliance now stand against Onaga and his supporters. Onaga now seeks to use six artifacts called Kamidogu, which are able to destroy the realms. Raiden awakes and then unleashes all his powers in a colossal explosion that, apart from destroying both members of the Deadly Alliance, the surrounding palace and himself, has little effect on Onaga. When Quan Chi wins, the Dragon King Onaga, the former emperor of the realm of Outworld, appears to regain his power. With Raiden defeated, the Deadly Alliance dissolves as the two sorcerers turn on each other for Shinnok's amulet. In the final events of Mortal Kombat: Deadly Alliance, Raiden's warriors, who were meant to protect the six realms, are killed by the Deadly Alliance (Shang Tsung and Quan Chi), who attempted to conquer the realms.

The latter is used when the phrase 'Finish Him/Her' is shown on the screen and the player is about to lose. In contrast to Deadly Alliance, in which characters had only one Fatality, the Deception characters have two Fatalities and a hara-kiri suicide move. The game also introduces the 'Combo Breaker', a system which allows players to interrupt combos up to three times per match.

The game's arenas are similar to those in Mortal Kombat: Deadly Alliance, but include new features such as unique weapons which players can use, and instant-death traps which immediately kill a fighter who falls into them. It was released for the Nintendo GameCube in March 2005.

Mortal Kombat: Deception is a fighting video game developed and published by Midway as the sixth installment of the Mortal Kombat franchise.
