Rayman Legends will include around 40 levels from Rayman: Origins, thanks to the inclusion of a 'Back To Origins' unlock within the game.
In an interview with Shack, Ancel said that the original levels were included since the game never released on Wii U. Many may have played these levels already of course, however they are included for free, so it's hard to grumble.
The chapter will contain the best levels of Origins and have been remastered for Wii Us' gamepad. Which is obviously pretty ace.
The bonus content will come to all platforms, which includes PS3, Vita, Wii U and Xbox 360. Rayman Legends is out this September, you can pre-order below.
