Originally announced at E3 in 2011, we should finally see the 3DS version in Summer, with the Wii U version coming later in the year. With the series originally starting on the Nintendo 64 in 1999, this will be the forth title in the Smash Bros. franchise and see the game moving to a mobile platform for the first time.
As well as different art directions and character models for both titles, players will also experience different level design depending on the platform they are playing on. Wii U players will experience levels based on previous console titles and Super Smash Bros. games, with 3DS players battling it out on levels based on 3DS titles. Nintendo also mentioned some cross-compatibility between the titles, with more details expected closer to release.
The most interesting piece of information from Nintendo is the promise that the game will run at 60 frames per second on the 3DS. If Nintendo can pull this off and guarantee a buttery smooth experience, it could be my choice for multiplayer gaming on the move.
