Another big update is coming very soon to Monster Hunter World. Capcom will release a new patch for both the PS4 and Xbox One versions tomorrow, April 18, which will introduce new gear, another Elder Dragon, and a new type of quest to the game.

The update is scheduled to roll out at 5 PM PT / 8 PM ET (1 AM BST on April 19). Most notably, it introduces a new Elder Dragon to hunt: the gold-plated Kulve Taroth. "Cloaked in a heavy golden mantle, this dazzling threat is fast approaching and it's up to you and your Hunting Squad to work together and repel it at all costs," Capcom said in a post on the PlayStation Blog.
