Mario & Sonic at the Sochi 2014 Olympic Winter Games

Mario & Sonic at the Olympic Winter Games Sochi 2014 is an upcoming Wii U game and is the fourth installment of the Mario and Sonic series. It was first announced by Satoru Iwata on Nintendo Direct on 17 May 2013, as the second out of the three titles of SEGA and Nintendo's exclusive collaboration, the other confirmed one being Sonic Lost World. It is also the first game in the series published by Nintendo outside of Japan and South Korea rather than SEGA, who published the first three games.

Gameplay
Mario & Sonic at the Olympic Winter Games Sochi 2014 will feature sixteen events, including a wide variety of Olympic winter sports, including skiing, snowboarding, bobsledding, pairs figure skating and curling. Players will have to use both the GamePad and the Wii Remote Plus, depending on the event in question. Curling, for example, requires players to draw lines on the GamePad's screen.

The game will also include special events set in the world of Mario and Sonic, in which characters have special abilities not possible in the real world. Mixed events that combine sports like skiing, snowboarding and bobsledding in one race, will also be available. Figure skating can now be performed with two characters on the same team, team-working simultaneously.
