Year of Luigi Secrets

How do I unlock Luigi Bros.?

2013 is the year of Luigi, and Nintendo continues the celebration in Super Mario 3D World. Turns out, you can unlock a special version of the original Mario Bros. game (not to be confused with Super Mario Bros. on the NES). What makes this edition stand out? Both characters are Luigi.

You can unlock Luigi Bros. one of two ways. The easiest way is to purchase a copy of New Super Luigi U and have a save file on your Wii U console. This unlocks Luigi Bros. automatically, and you'll be able to play it by pressing the Luigi icon on the lower left corner of the GamePad touchscreen.

If you crave a challenge, beat the first eight Worlds in Super Mario 3D World.
