Prince of Persia: The Two Thrones is an action-adventure game blending acrobatic platforming, puzzle-solving, and hack and slash combat, and the final chapter of the Sands of Time trilogy. Players guide the Prince through the city of Babylon, running along walls, leaping between platforms, avoiding traps, and using the time-controlling Dagger of Time in combat and to recover from mistakes. A new Speed Kill system rewards well-timed stealth strikes to take down enemies quickly, and the Prince can wield secondary weapons taken from foes. At points he transforms into the Dark Prince, an alter ego that fights with a bladed whip called the Daggertail while steadily draining health. It was later ported to PlayStation Portable and Wii under the title Prince of Persia: Rival Swords.
