The 2018 International Battle Pass grands interesting things for Dota 2 players like The Underhollow. The Underhollow is a brand new game mode which lets three-player teams fight over cheese.
Roshan is on a ravenous, cheese-fueled rampage and Battle Pass owners are invited to venture beyond the surface of his lair into the heart of the Underhollow.
Underhollow was not announced as a battle royale mode, but it actually is. You will 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.
Battle Pass owners will also have access to Cavern Crawl mode which will let you win games with designated heroes in your normal Dota matches to explore deeper parts of the battle cavern. The new Mutation mode, on the other hand, is an unranked game mode played with a random selection of gameplay modifiers ranging from global Rupture events to the ability to resurrect your teammates.
