Capcom Explain the connection between Monster Hunter 3 Ultimate for Wii U and 3DS
So you looking to get Monster Hunter 3 Ultimate, but not sure if you should get Wii U Version or the 3DS version. Well by now you must know they do work together.
“We wanted people to play together. We know there are some people who want to play online. Unfortunately with the 3DS version you can’t do that. But we have made this feature so you can play together. You can have your friends bring their save data to your house and have a Monster Hunter party. One person will play on the big screen and three other people will play with their 3DS versions. People can continue their save data from what they had before and go back home and update their data on their Wii U.”
