Cull the Pack is a mod for the Monster Hunter World game that will let you fight off the monsters in the Arena in the same way you've been doing in the Monster Hunter game for years. It will let you fight with your friends in the Arena, but this time, you'll be fighting a whole different kind of monster. They're called Great Jagras, and they're Arch-tempered. They're going to be a real challenge to fight, and the first thing you'll have to do is defeat them in the Arena.
