Valve's Dota 2 documentary Free To Play will be released on 19th March for free via Steam.
Free To Play was created internally at Valve, and digs into the lives of three professional Dota players as they compete in the first Dota 2 International Tournament.
The players are Ukrainian Danil "Dendi" Ishutin, Singaporean Benedict "HyHy" Lim and North American Clinton "Fear" Loomis.
There's an advance screening in San Francisco, if you're able to get to that part of the world, on 18th March, at the Castro Theater.
Over seven million people play Dota 2 each month, Valve said. The company will sell the Free To Play pack on Steam and the Dota 2 Store, with 25 per cent of the sales given to the players in the film as well as the contributors. The pack contains a number of in-game items for use in Dota 2.
