Despite still being in closed beta, Dota 2, the upcoming online game from Valve, has over 3 million unique monthly players, according to Valve.
Dota originally appeared as a mod for Warcraft III and Valve quickly hired one of its main developers to work on a full-fledged sequel built from the ground up as a new experience.
This new title, Dota 2, was released as a closed beta more than a year ago, and since then the number of players enjoying the strategy title has grown exponentially.
Now, Valve has confirmed, via CVG, that over 3 million unique users are playing the game every month.
The studio didn't say anything about putting the game in an open beta, but the title will be free-to-play once it's eventually released via Steam for PC, Mac, and Linux at some point in time.
