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. * Mario collects stars as he travels from galaxy to galaxy. Every level is new, but the game retains the charm, sense of wonder and beauty in line with Marios history. Mario works his way through the various levels, sometimes upside-down, sometimes floating from place to place. * On some stages, Mario can find an egg, smash it open and hop onto the back of Yoshi. Yoshi can use his tongue to grab items and shoot them back at enemies, or to snag attach points and swing across chasms. * Yoshi has an interesting diet. When he eats a Dash Pepper, he gets so hot and frenzied he can run up steep inclines and vertical walls. When he eats a Blimp Fruit, he inflates like a balloon and floats to new heights. * New power-ups include a drill that Mario uses to tunnel through the planets surface all the way to the other side of a planet. * Skilled players will want to collect new Comet Metals, which will unlock harder levels with even more challenges.
