Want to put the fear of a fancy and fashionable assassination into your foes in Prince of Persia: The Forgotten Sands? Then get thee to the nearest Ubisoft game and sign up for their Uplay scheme.
To make the Prince of Persia look a lot more like Ezio from Assassin's Creed II, you'll need to acquire Uplay Win "units," based on your accomplishments in various Uplay-enabled Ubisoft games. It's free, you'll just need to meet the Uplay requirements to do so.
If you'd prefer to look like the Prince's brother, Malik, you can apparently text message the word PRINCE to 44144, if that makes sense.
