Nintendo has announced that Capcom’s Monster Hunter 3 Ultimate for Nintendo 3DS will only be able to go online using a special Wii U adapter. The game will require a special LAN adapter that plugs into the Wii U, and a relay download tool is also required. The complex setup means that the Wii U version of the game can’t be played at the same time that the relay tool is being used for the 3DS version. You won’t be able to create a four player lobby, instead you will only be able to join a lobby that has been setup by a Wii U owner. The tool has only been announced for Japan so far.
