It is sometimes the case that free DLC is a little paltry, but MH4U is providing some great extras for free. There are 14 new quests, but perhaps the most fun element is new Devil May Cry and Animal Crossing themed outfits for your characters. Capcom have produced a detailed trailer for the DLC that highlights the various quests that you will get:
]]>Monster Hunter 4 Ultimate includes everything from MH4 but, you know, more. There are two new weapons classes (Insect Glaive and Charge Blade), new beasties, new sub-species, and plenty of new locations to explore. Underwater combat is gone (no one has shed a tear so far). Air combat is now a thing, but don't think you'll be flying around like a bnahabra. Instead, hunters have leaping vertical attacks to unleash, which includes latching onto monsters' backs and stabbing away. You know how launching players is generally considered a bad thing? Now you can launch them right onto monster's backs. It's tactical, dammit!
