Mario & Sonic (tentative name) is a 2D Platforming video game coming out for the Nintendo DS. Despite being 2D, the actual Gameplay is made to match that of the Sonic Adventure series, or the Super Mario series. It features several Mario and Sonic characters, in their mission of defeating Bowser and Dr. Eggman, who have joined forces to capture the Mushroom Kingdom. It has been confirmed there is a very large amount of playable characters, but many will be playable in different sub-stories of the game. Not much is currently known about this game, other than the information given above.
