Dota 2 officially free to play, all heroes will be free, store to sell community-created items

Unusually close to our bedtime, Valve has launched Dota 2‘s microtransaction shop as it formally declares the game free to play. Click here to read the fancy Dota 2 Store announcement page.
We expected Dota 2 to be a free-to-play game—that’s barely news. But more noteworthy is the confirmation that all of the game’s playable heroes will be free with no limitations, that Dota 2 will utilize Steam Workshop, and that, like TF2, the Dota Store will be putting player-made items on sale. 67 items are in Dota 2′s section of the Steam Workshop now, and almost 200 are in the Dota Store.
Dota 2 will release on PC later this year, Valve says. Expect a big coming-out party for the game during The International at PAX Prime.
