No Online Functionality For 3DS Version
Capcom has announced a couple of fairly divisive tidbits regarding Monster Hunter 3 Ultimate's multiplayer, which is headed to both Wii U and 3DS as a cross-compatible title. Apparently it will run on Nintendo's own servers, but the 3DS version will have no online multiplayer whatsoever.
Taking to the Capcom Unity forums, senior vice president Christian Svensson explained that MH3U will leverage Nintendo's server infrastructure, which they still need to thoroughly test over the next six months.
“For Wii U we’re using Nintendo’s servers (which I’m very happy about) and I’m not sure how they’re set up. Candidly, we’re still waiting for Wii U builds in our office to play with and there’s still many moving parts that no one except for the team members has first hand experience with at this point."
“We have six months until release (roughly). We’ll have a lot more detail on these and other questions (most of which we DO know the answers to) as we move through the communications/marketing campaign and run-up to launch.”
Sadly, Monster Hunter Tri servers will be shut down - so if you still play the Wii title online, you'd best make the most of it while you can.
There's bad news for the 3DS version, however, in that the near-identical portable build will not support online multiplayer. Capcom’s Yuri Araujo told ONM that there are "no plans” to add online support, though you can of course swap your save file over to the Wii U game and play it that way.
Monster Hunter 3 Ultimate is headed to Wii U and 3DS next March.
