Blizzard's MOBA, Heroes of the Storm, goes into closed beta tomorrow.

Ahead of its release, Blizzard has cut a new video that explores some of the features coming in the latest edition of the game, including ranked play, new content, the new user experience, and the shop.

Key additions include a new map called Sky Temple and a new hero, Thrall. In the closed beta, the individual Hero League will be added to the game. The Team League is still in development.

There will be regular sales on the shop, Blizzard said. There's also a new item in the shop, Stimpacks. These will ramp up gold and experience gains over a period of time.
