Valve has announced that Free To Play, its in-house documentary that follows the lives of three Dota 2 players, will be released on Steam on March 19.

The publisher has released a new trailer for Free To Play, which you can watch below.

The film will premiere in San Francisco a day earlier, on March 18.

Each person who purchases the film will receive the Free to Play Competitor Pack. The Dota 2 pack includes an in-game courier, a special ward, and a custom HUD skin. A portion of each purchase will also go to the players featured in Free To Play.

Dota 2 came out of its two-year beta in July 2013. It has more than 7 million active players.
