If you didn't have a chance to take down the Mother Goddess of Gold the last time she was available in Monster Hunter: World, you'll be able to try again soon on Xbox One and PS4. The Kulve Taroth siege is returning to the title on May 24.

Revealed on Twitter, Kulve Taroth will become available on in the US May 24 at 5 PM PST and in Europe May 25 at 1 AM BST. An end date has not yet been announced. To take on this siege, you'll have to be hunter rank 16 or higher, and team up with your friends to get the epic, golden loot for your hunter and palico.
