As promised, another 3DS demo is available on the eShop, this time for Mario & Sonic at the London 2012 Olympic Games. It may not have zombies, but then, it may have Waluigi. Renegade Kid's Mutant Mudds, its first self-published project, is also up on the eShop this week, offering challenging platforming and shooting and some dramatic 3D effects.

DSiWare features a sequel to the indie game Flipper; though if you played it, you still won't recognize Flipper 2: Flush the Goldfish. The original was an isometric puzzle game about reshaping environments ... and the sequel is a side-scrolling action game that uses one contextual button!
