Monster Hunter 4 Ultimate's crossovers so far include Link, Samus, Animal Crossing, Sonic the Hedgehog and Taiko Drum Master. Capcom this weekend announced a new one: Mega Man, in the form of gear for Monster Hunter's palico companions.
See the video for what that means, but it's basically a cat running around in Mega Man armor, swinging the helmet of the Blue Bomber's faithful dog.
These special items will be available for the Western version of the game when it launches early next year. (It's already out in Japan, where Samus herself will be playable in-game come December.)
