Unlockable Luigi Bros. Mini-Game
A modified version of the classic Nintendo arcade game Mario Bros with Luigi can be played from the menu screen. It can be unlocked in two ways - the first is to get a copy of New Super Luigi U and have a Save File of the game on your Wii U prior to starting the game or to beat the first 8 Worlds of the game and unlock it.
There are many hidden 8-bit Luigis throughout the game, they can be found within levels, in overworld maps and in minigames. These can be found by hitting ‘?’ blocks or by seeing them through binoculars during certain moments.
