The company broke the news during their Nintendo Direct conference, offering up a handful of screenshots, which - surprise, surprise - bear a striking resemblance to the other New Super Mario Bros. titles we've seen in years past. Nintendo described the game as an "all-new, side-scrolling adventure" featuring "Mario, Luigi and all your fave characters from the Mario series." Nothing all too surprising there.
Since this is the first title in the sub-series to come to the 3DS, it will be interesting to see how they plan to incorporate the 3D visual element into the gameplay. They managed to do some pretty cool stuff with Super Mario 3D Land, so here's to hoping that they don't just play it safe and give us the same old Mario experience.
