Valve has released Dota Underlords in Open Beta. Players can get the game for free and play on Steam (Windows, Mac, Linux), Android and iOS. Currently the game can be played both online and offline and supports crossplay between platforms.
The game will be in early access for several months, during which the developers plan to add multiple new features, including Ranked Matchmaking, Battle Pass, Tournament Lobbies, and Match Replays. Besides that, the developers will introduce an ability to choose one of four Underlords that affect gameplay, as well add seasonal rotations of heroes, items and alliances.
Dota Underlords is a standalone game heavily inspired by the Dota 2 community-created mod Dota Auto Chess. In less than 12 hours since release the game has already peaked at 110,000 concurrent players and reached 4th place in the Steam most-played games list.
