While the plot of Unchained hasn't changed since 2004, the roster of the game has been boosted for the PSP version. This, of course, leads to various characters within the MK universe fighting it out, each attempting to eliminate Onaga for their own personal reasons. The combined strength of Shang Tsung, Quan Chi and even Raiden working together isn't enough to dent the Dragon King, and even a desperate suicide attack from Raiden doesn't faze the beast. Unfortunately for the two treacherous sorcerers, a nasty surprise shows up when Onaga returns to reclaim the throne of Outworld. Unchained's story picks up where MK: Deadly Alliance left off, with Quan Chi and Shang Tsung successfully resurrecting the army of the fabled Dragon King before they turn on each other.
