Super Crash Bros. 2

Super Crash Bros. 2 is the sequel to Super Crash Bros.. This time, the game is compatible with 3DS and Wii U.

Gameplay
The gameplay is typically the same (each version has its own controls, obviously) as the previous game. However, the glittery grounds are absent, and in the place of abilities, a new feature called Item Craze is introduced, which can only be triggered during a Team Race. Speaking of Team Race, it is a more dominant racing mode in this series, though you can still play in the regular way in modes like Quick Race and Tournament.

As the theme involves teaming up, the racers are divided into several teams based on the kart color (Blue, Red, Yellow, Green). This comes into play in the Team Race where you cannot hit your own teammate and the latter's presence is required to fill in the Team gauge that can be used to trigger Item Craze when it's full. During Item Craze status, you'll be given an unlimited supply of items for a short time.

This game, unlike the first, has an Adventure Mode, which is in the style of the one in Diddy Kong Racing. There, you progress through the story as one of the teams to win all cups and defeat all challengers. You can also obtain many more goodies and unlockables there.

Adventure Mode
Play through the story involving all of the playable racers racing against each other to win cups. The entire Adventure Mode area is divided into five zones, and each zone has a challenger waiting for you. Defeating a challenger will make you able to access the next zone. Aside from defeating all challengers, you can also obtain Colored Coins (required for accessing hidden "cup races"), Character Trophies (unlocks the respective character when obtained), and Time Medals.

1P Race
A single player mode. Contains Quick Race and Team Race.

Multiplayer
Play with or against your friends in this mode. Contains the same modes as 1P Race.

Tournament
Play through various cup races. The racer with the most points at the end of the cup race is the winner.

Battle
A multiplayer-only mode. Battle against other racers in five different arenas. This mode is divided into five sub-modes: Car Fu, Blast to Score, Last Man Standing, Capture the Flag, Shine Run.

Time Trial
Set your own best times here. You can also race against a "ghost". If you can win against a "ghost" in every track, something good will happen.
