Yes, it’s true! Yuri posted on Capcom Unity about the boxart along with the announcement:
"I’m proud to confirm that multiplayer in Monster Hunter 4 Ultimate will work amongst both North American and European versions, online AND locally!
So whether you have friends on the other side of the pond or you’re traveling abroad, you can still join your fellow hunter and take on majestic beasts!”
We look forward to hunting with everyone!
You hit it until it dies.
Good ole Cuppa Jho.
I’ll take mine with about three servings of pain.
