Monster Hunter 3 Ultimate's core gameplay is that the player hunts Monsters for quest. However, to take down stronger monsters, it requires many materials for stronger gear. Each type of weapon plays relatively differently
This entry combines elements of both Monster Hunter Tri, like the underwater combat, and Monster Hunter Portable 3rd like certain weapon types like the gunlance, bow, hunting horn and dual swords.
The game also reintroduces G rank, a level above high rank that features a new set of quests, harder monsters and improved weapons and armor. This is the first time G rank has been present in a Monster Hunter game since Monster Hunter Freedom Unite.
