The Underhollow, the Dota 2 (opens in new tab) battle royale with cheese mode that was announced in May, is now live (opens in new tab). The new mode is available exclusively to owners of the 2018 International Battle Pass, a multi-level offering for Dota fans that also includes new modes, sprays, a Cavern Crawl, and other rewards.
The Underhollow pits eight teams of three players each against one other in a great quest for Roshefort, the rarest of all cheese located in the caverns beneath Roshan's lair. But the other cheese-chasing teams are just the start of your problems: Roshan himself is also that sharp, savory flavor, and his rambunctious roaming is causing the tunnels to collapse, slowly constricting the playing area.
The last team standing will earn a hefty bounty of Battle Points, which can also be claimed (in smaller amounts) by taking out opposing players and discovering treasures or cheese. (Which isn't to say that a good cheese isn't a treasure, but you know what I mean.)
The level 1 Dota 2 International Battle Pass goes for $10, while the level 75 is $37. You can also purchases levels separately if you want to upgrade your pass to take advantage of higher reward tiers. Full details are available at dota2.com (opens in new tab).
