Sort of… Players who buy Rayman Legends on Wii U get an extra bonus unique to the Wii U version — Mario and Luigi outfits. Not the actual characters, but outfits that the character wears.
Players don’t have immediate access, however, but they may as well. All that’s needed to unlock the costumes is 20 minutes of gameplay. If you can stomach that then the costumes are yours. Geez, what’s that saying about the gameplay? Kidding. I hope.
The new outfits were teased in a cool Mario and Luigi Rayman Legends trailer, which you can watch above.
