The Super Luigi U DLC for New Super Mario Bros. U is being released as a digital download for the game on June 20 in both North America and Europe. However, it's also coming to retail as a packaged standalone. It'll be available August 25 in North America, and July 26 in Europe. The DLC will be priced at $19.99, while the standalone is $29.99. You won't need NSMB U to play the packaged game.
This morning's Nintendo Direct also revealed that Nabbit, a little critter who you chased in the first game, is a playable character in the new content. He'll be available in multiplayer games as an easier alternative to Luigi and the Toads. He won't take damage when he touches enemies, but to balance that he won't be able to use power-ups.
Super Luigi U makes changes to NSMB U's campaign to make every course "all-new" - it's essentially a new Luigi campaign.
Nintendo has revealed that Wonderful 101 will land on the Wii U on September 15 in North America and on August 23 in Europe. Coming from Platinum Games, Wonderful 101 sees players wielding ordinary citizens as weapons. It's as nutty as it sounds.
In a "one more thing" moment on the latest Nintendo Direct, Big N president Reggie Fils-aime announced a special partnership with Best Buy. During the week of E3, the big box electronics store will be hosting playable demos of unreleased Wii U games. Presumably, these will be the games that Nintendo is showing off during the industry's annual trade show, but Fils-aime did not reveal specific titles.
The week of E3 begins June 9.
Sega and Nintendo have entered into a "worldwide partnership" on Sonic games, and the first fruit borne from is Sonic: Lost World. It's coming to Wii U and 3DS, and there'll be more news on it prior to E3.
Nintendo president Satoru Iwata said on this morning's Nintendo Direct, "Sonic: Lost World is a brand new action-adventure platforming game that will launch exclusively on Wii U and Nintendo 3DS."
