Dota Underlords has got off to a flying start. After launching into open beta, Valve’s own official take on the emerging autobattler genre rocketed up the charts to become one of the most played games on the platform – less than 24 hours after launch.

According to Steam’s concurrent player stats, there were more than 170,000 people playing Dota Underlords on the day of launch – making it the fourth most-played game on the platform behind CS:GO, PUBG, and Dota 2 itself, and well ahead of Rainbow Six Siege. Today’s player count peaked at 202,334.

Those numbers, have already blown some of Valve’s biggest games out of the water. Team Fortress 2’s all-time concurrent player record is just under 123,000, while Artifact floundered to a peak of around 60,000 (and currently boasts a 24-hour peak of just 179 players, to put these figures in some further perspective).

Given that Underlords also launched on mobile, it’s likely that these numbers aren’t the full story. The game has already been downloaded more than 100,000 times on the Google Play store, and figures from that version aren’t likely to be counted via Steam.

It’s an undoubtedly strong start, and as I said, those numbers are only likely to climb over the course of the day. Valve does, of course, have a major competitor in the new genre – League of Legends developer Riot recently unveiled its own take on the genre in the form of Teamfight Tactics. It looks like that’s proving popular too, as TFT – which is currently only available via LoL’s PBE testing servers – is creating hours-long queues. As Valve and Riot start square off, it’s looking like the early 2010s all over again.
