An unofficial, non-commercial quest randomizer for Monster Hunter 3 Ultimate — it rolls a quest and a weapon for when you can't decide what to hunt. Not affiliated with, endorsed by, or supported by Capcom.
Every quest — its name, star, locale, objective and monsters — and every Arena loaner set is read from the game's own quest files, and the monster, quest and weapon icons and the Guild Card backgrounds are the game's own. Everything was extracted from a personally owned copy of the game; no game files are redistributed. Downloadable Event and Challenge Quests aren't on the cartridge, so they aren't in the pool. The monster classes in the Monsters filter are assigned by hand.
Monster Hunter 3 Ultimate and all of its names, data and icons are © CAPCOM CO., LTD. The UI textures and the MHFU font are shared with the same author's MHGU fan apps, and the app itself is a port of the MHGU Quest Randomizer.
