Mario Kart X-Treme

Mario Kart X-Treme, also known as Mario Kart 11 in Japan, is a kart-racing game exclusive to the Nintendo HDS. It is the eleventh Mario Kart game in the series. Much like Insanity and Halfpipe Frenzy, Mario Kart X-Treme uses HammerBro101 Wi-Fi Connection. The amount of racers returns to 12, just like Wii and 8.

Roster
There are 20 returning characters, as well as 4 new ones.

Items
Mario Kart X-Treme introduces two new items: the P-Switch and the Special Crown. The special items from the two previous installments are absent from the game. The Thunder Cloud and Super Leaf, which were absent from Halfpipe Frenzy, return in this game.
