"Prince of Persia: The Fallen King for DS puts the hero on a dangerous quest to stop an evil god named Ahriman, who has flooded the land of Persia with a dark oozy corruption. Helping him out is his sidekick Zai, who can conjure up tools that will help the Prince on his way.
Like the console editions, Prince of Persia is all about the team effort. You'll take control of the prince most of the time, but call upon Zai if you need a wall created or hooks for the hero to grab onto in order to reach new areas. It's an interesting premise, although we feel that Elika, from the console versions, is a more effective colleague. Her magical abilities not only aid you in both battle and puzzle solving, but she also keeps you in one piece. Zai, on the other hand, isn't exactly user-friendly."
