Monster Hunter World released for PS4 and Xbox One last month, but one of the biggest incentives to pick the game up on Sony's console is an exclusive set of Horizon Zero Dawn DLC armor. The gear has been available since launch through a limited-time Event Quest, but it won't be around for much longer.

The first round of Monster Hunter World's Horizon collaboration event ends at 3:59 PT / 6:59 ET / 11:59 UTC on February 8, making this your last opportunity to embark on the quest. The mission is called Lessons of the Wild, and it's a five-star quest available to players who've attained a Hunter Rank of 6 or higher. The object is to hunt eight Barnos, which will net you the materials needed to craft the Watcher armor and Felyn Watcher Grinder weapon for your Palico. You can take a look at the gear below.
