Luigi Bros.

A port of the game known as Luigi Bros. is included in Super Mario 3D World as unlockable content, with the only difference being that Mario is replaced by Luigi in his current appearance (green hat and shirt with blue overalls); player 2's Luigi retains his original appearance (white hat and shirt with green overalls, similar to Fire Luigi's color scheme in later Mario games). If the player has save data of New Super Luigi U, Luigi Bros. can be played straight away without having to be unlocked.
