Today 3 new gameplay trailers for the next game in the Super Mario series. Super Mario Galaxy 2 is using the same graphics engine as the first game and will release some time in June in Australia.The game is described by the developer below.
Super Mario Galaxy 2, the sequel to the smash-hit galaxy-hopping original game, includes the amazing gravity-defying, physics-based exploration from the first game, but is loaded with entirely new galaxies and features to challenge and delight players. On some stages, Mario can pair up with his dinosaur buddy Yoshi and use his tongue to grab items and spit them back at enemies. Players can also have fun with new items such as a drill that lets our hero tunnel through solid rock.
