Capcom’s best-selling game ever, Monster Hunter World, is receiving an expansion called Iceborne on Sept. 6. While supplies last, pre-orders of the game’s Master Edition receive a Steelbook case.

Currently available for $79.99 through Amazon, the PlayStation 4 and Xbox One Master Edition versions both come with the full 2018 title Monster Hunter World, its Iceborne expansion and various downloadable content. Capcom’s Twitter account hints that the included Steelbook bonus is extremely limited.

Monster Hunter World holds a 90 from review aggregate site Metacritic. The game is credited with bringing the niche gameplay of the Monster Hunter franchise to mainstream audiences.
