Super Mario Galaxy 2 [video game]

• Skilled players will want to collect new Comet Metals, which will unlock harder levels with even more challenges

• Mario collects stars as he travels from galaxy to galaxy, 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.

• New power-ups include a drill that Mario uses to tunnel through the planet's surface all the way to the other side of a planet

• Every level is new, but the game retains the charm, sense of wonder and beauty in line with Mario's history

• Yoshi can use his tongue to grab items and shoot them back at enemies, or to snag attach points and swing across chasms

• 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
