The PSP version of "Prince of Persia: The Forgotten Sands" is a side-scrolling 2.5D platformer that roughly follows the same style as the other versions. It has a different storyline involving freeing the Sisters of Time, a different setting and antagonist.

The game features a plot in which the prophecy is written that a member of Prince's royal family will bring an end to an evil fire spirit Ahihud's dark reign over hidden mystic land. To ensure his survival, the evil spirit's minions hunt down those with the royal blood of Persia. Prince escapes his tower, where he is kept protected by his father, and pursues a mysterious guiding light, which turns out to be Helem, a spirit of Time who promises to help the Prince defeat his enemy. Together, they journey to a mysterious, hidden kingdom which is revealed to be the holy site where the first god came to create universe. The kingdom is fully under control of Ahihud, who aims to devour the land's magical energy, the Elixir. The player has to confront Ahihud's sand monsters, collects Elixir to boost his own strength and vitality, and find portals to spirits realm, where Helem's sisters are to be freed. Each freed Sister of Time grants Prince a new ability to control time, like freezing a selected spot or creature, or hasting it. After making his way through the mystic land, Prince defeats Ahihud's two most powerful servants, the gigantic guardian of the palace and the sand assassin, who was created to hunt down Prince's relatives. In the end, Prince is able to kill Ahihud in his own domain in spirits realm, fulfilling the prophecy and restoring the mystic land to its former glory.
