Nintendo revealed today a new co-op mode for New Super Mario Bros. 2 on 3DS.
The new mode will, unlike the first NSMB. on DS, allow for two players to play through the single-player campaign levels co-operatively (or competitively if you so wish) - much like the NSMB. Wii.
Nintendo demoed the new mode, showing how the camera follows the leading player, who can either wait for their straddling partner or run on and cause them to die off-screen.
Nintendo also revealed a new Coin Rush mode, which has players speed-run through levels collecting as many of an abundance of coins. Their final score at the end of a three-level run combines collected coins with their left-over time (hence the need to rush) at the end of the run, and saves this to a scoreboard.
These scores are exchanged with other players via StreetPass, who can then compete to beat their scores in the same levels. This mode also contained a new item - the Gold Fire Flower - which has Mario shooting fireballs that turn blocks and enemies into coins.
The game's out in US on August 19. Check out the E3 2012 trailer here.
