The first part of Monster Hunter World's Horizon: Zero Dawn crossover event is now over, meaning PS4 players can no longer get the Watcher gear set for their Palico. However, the second part of the event is on the way in a couple of weeks, and now Capcom has shared some more details to help players prepare for it.

The next Horizon-themed Event Quest is called The Proving. While we don't know exactly what the quest will entail, Capcom has revealed that it involves hunting down a giant Anjanath. You'll also need to reach Hunter Rank 11 or higher before you can accept the quest.
