Super Mario 3D World

Super Mario 3D World (otherwise known as Super Mario 3D Land II) is an upcoming 3D platformer action game for the Wii U. It is set to be released in December 2013. It is the fifteenth title in the Super Mario series and the sixth 3D Mario title. This installment is the direct sequel to the Nintendo 3DS game, Super Mario 3D Land.

Gameplay
The game plays very similar to Super Mario 3D Land, being closely based on the 2D side-scrolling games, while being a 3D platformer, like Super Mario 64 and the Super Mario Galaxy games. This game retains its predecessor's similarity to Super Mario Bros. 3 (with colorful blocks, the Super Leaf, Spikes and the Lose a Life theme returning from that game), however, many elements from Super Mario World are returning as well, such as the Chargin' Chucks and the round version of Goombas. Lives also make a return, but in multiplayer mode, players share their lives. Stages are once again open, yet linear, have a time limit and end by grabbing the classic Flagpole at the end. Green Stars return from Super Mario Galaxy 2, taking the role of the Star Medals from 3D Land.

Power-ups, like the Fire Flower and Super Leaf make a return, along with a new power-up; a bell that grants the player a Cat Suit, allowing the player to lunge at enemies and climb up walls. The can also be used to unveil hidden blocks and objects, as well as stun enemies and platforms, like the Co-Star Luma from Super Mario Galaxy 2 and Boost Mode from New Super Mario Bros. U. The game also supports Off TV Play. Also, the can be used to control the camera during gameplay. It works in a similar fashion to Super Mario 64 and Sunshine's camera.

The game features 4-player multiplayer (the first for a 3D Mario game), allowing players to play as Mario, Luigi, Blue Toad and Princess Peach, each with different abilities, much like they had in Super Mario Bros. 2. Also, the first player has a choice to play as any character, unlike in the previous multiplayer Mario platformers where the first player must use Mario. The way the players are ordered is this: Gamepad, Player 1, Player 2, and Player 3.
