A lucky journalist managed to get some hands-on time with the DLC for New Super Mario Bros U, New Super Luigi U. You can see from the above video that the game looks far more challenging than New Super Mario Bros U. Those pesky Star Coins look like they’re going to require some platforming magic to acquire. New Super Luigi U launches on the Wii U eShop on June 20th and will cost $19.99. The retail version will be released next month in Europe and August in North America.
