Here's a feature everybody's been wanting for New Super Mario Bros. 2 — it has a two player co-operative mode.
You can run through the entire 3DS platformer alongside a friend, taking control of a Mario Bro. each. There are a couple of stumbling blocks though: both players need to own a copy of the game, and it's also only playable over local wireless. No online for you.
A high score StreetPass mode has been announced too. In Coin Rush you've got to grab as much gold as possible over the course of three levels. Your record is passed out wirelessly for potential gold diggers to beat.
We've added some new screenshots to the gallery below. What're your thoughts on these additions to New Super Mario Bros. 2?
