You'll be able to save data across both versions. To do this, you'll have to download a free app from the 3DS eShop, which you'll use to transfer data from the Wii U to the 3DS and vice versa over wi-fi. With this function, you'll be able to continue your Monster Hunter game on the move. A Wii U console and up to three Nintendo 3DS consoles can communicate for four-player local co-op play over wi-fi. Using this, in combination with the data transfer between consoles, means you'll be able to invite your friends over for what Capcom hopes will be Monster Hunter parties, them bringing their data files on their 3DS to communicate with a Wii U, and all four players playing in the same game. http://www.eurogamer...s-work-together I have no monster hunter friends capcom, y u not put online on 3DS!!! "We didn't have the correct techniques to get it to work. But monster hunter 4.... It's pretty cool to see 3DS do crossplay with a HD console.
