The iPhone Game of the Year Rayman Jungle Run is getting a free update with a host of new stages and challenges, Ubisoft announced today. The update is available now, and adds 20 new stages in all.

A trailer shows off the new stages. It includes two new levels in the Land of the Livid Dead, a pirate ship, and a "boss pursuit" chapter in which you have to outrun a giant red monster.

The game is available for $2.99 on App Store and the Android Market. The update will be applied for free if you already own the game.
