It's crazy how many missions there are
Monster Hunter 4 Ultimate is the gift that keeps on giving. Steadily since February Capcom has provided free DLC updates, ranging from Nintendo and Devil May Cry costumes to new missions. It's very un-Capcom-like, but there you go.
August will bring 10 new quests, four challenges, a purple Palico, and more guild card options. After this, Capcom is teasing more free DLC for September.
