At a press event last week, Nintendo announced the latest two downloadable expansion packs for New Super Mario Bros. 2 on 3DS. These being the ninth and 10th packs available, if you need a refresher, you can catch up here.
The Mystery Adventures pack opens up the game's structure with more exploration and side paths, while the Impossible pack offers a series of stages built to frustrate.
Nintendo had the Impossible pack on display at the press event, and it almost stood up to its name. I'm far from a competitive Mario player, and I attempted the first stage about 20 times, getting three-quarters of the way through on my best try. A Nintendo representative on hand said it took him about two hours to initially clear the first stage.
Both packs are available for download now.
