Dota 2 Gets Battle Royale and Battle Pass

The widely popular MOBA by Valve, Dota 2, released its very own Battle Royale mode alongside an International Battle Pass with a lot of unlockable goodies.

Dota 2's site describes the new Underhollow game mode:

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.
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.
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.

While Dota 2 is free to play, the Battle Pass does cost real-world currency, $9.99, and includes ways to raise your level through further purchases. However, the features are cosmetic and HUD altering changes only. In no way does the Battle Pass effect the gameplay.

Another mode that's coming to the game is Mutation. It will feature global wide events of hero abilities affecting each player at random times during, what seems to be, a standard match.  

The Battle Pass is also featuring a couple of new cosmetics, goals, and even a role-based matchmaking system so you won’t be stuck with five carries on the team.

Some of the new cosmetics include custom creeps, allowing you have your own beautified versions of Dires or Radiants to help push the lanes toward victory. As usual, players are able to vote on the new Arcana item and three troves of treasure, each with their own ambient effects and sounds for individual heroes. The Treasure II and Treasure III haven’t been revealed yet, but will be announced within the coming months.

A cosmetic change to make its way into Dota 2 is the ability to use sprays as visual emotes, which can be targeted at enemies and allies. After progressing through the Battle Pass, players will unlock other tags with more unique expressions.

Dota 2 is also hosting their yearly International Prize Pool:

Each year, the Dota 2 community comes together to raise the largest prize pool in all of esports. If the total surpasses last year's mark of $24,787,916, every Battle Pass owner will receive 10,000 bonus Battle Points. To sweeten the pot, you'll get another 10,000 Battle Points on top of that if the final tally eclipses $30,000,000.

The International Prize Pool has already peaked over $2,500,000.
