The 2018 International Battle Pass offers some very interesting new things for Dota 2 players, foremost among them The Underhollow, a new game mode that has three-player teams setting off on a competitive quest for cheese that sounds an awful lot like an underground battle royale.

"Battle through a labyrinth filled with monsters, marvels, and many other three-player enemy squads as you search for Roshan's rarest cheese and work to be the last team standing. You'll need to navigate carefully to earn the XP and Gold needed to destroy your opponents," the Battle Pass site say. "But don't take too long—Roshan's cheese frenzy is causing cave-ins as he moves towards the center of the Underhollow. Soon enough there will be nowhere left to run."
