Capcom recently showcased 25 minutes of Monster Hunter World gameplay during a Japanese livestream event, which you can check out above (from 46:36 to 1:11:17).
Here’s an official overview of the game:
Monster Hunter World introduces a living, breathing ecosystem in which players take on the role of a hunter that seeks and slays ferocious beasts in heart-pounding battles. Venture on quests alone or with up to three other hunters in a newly designed online drop-in multiplayer system which allows cross-region cooperative play between Japan and the West, uniting the global player base for the first time ever.
Monster Hunter World sees players gear up to venture on quests to battle against fearsome monsters, progressively improving their hunting abilities as they play. Loot collected from fallen foes can be used to create new equipment and armor upgrades as players seamlessly move across map areas that comprise the living ecosystems. The landscape and its diverse inhabitants play a critical role as players strategically use the surrounding environment to their advantage. Hunters must use their cunning and abilities to survive the intense and evolving fights as they battle to become the ultimate hunter!
Monster Hunter World will release in early 2018 for PlayStation 4 and Xbox One. A PC release will follow later in the year.
