Prince of Persia: Rival Swords

After many dangerous adventures, the Prince returns to Babylon, accompanied by his new bride, Kaileena, the Empress of Time. Their dreams of a peaceful and happy future together are dashed when they arrive in Persia to find the country devastated by war. The evil Vizier promptly captures and murders Kaileena, and her death unleashes the Sands of Time, from which the Vizier gains terrifying new powers. The Prince of Persia must fight once more, but this time he will be stronger than ever, thanks to his new alter ego, the Dark Prince, created due to the Prince’s contact with the Sands. As he fights to reclaim his kingdom from a madman, he must also battle his inner demons as the Dark Prince threatens to consume him entirely.
Regarding fight and puzzle sequences, the game is very similar to the previous installments of UbiSoft’s Prince of Persia trilogy: The Sands of Time and Warrior Within. Some significant innovations, such as the character of Dark Prince, periodically possess the main protagonist and offer him new combos and moves. There is also a unique ability called “Speed Kill,” which is highly effective against all enemies in the game (victims are attacked from behind and murdered brutally and stealthily).
