Blizzard will officially launch the company's long-awaited Massive Online Battle Arena game Heroes of the Storm on the Mac on June 2, preceded by an open beta on May 19.

The free-to-play game, which began development as a mod for StarCraft II, will offer players a way to have characters from Blizzard's franchises like StarCraft, Warcraft and Diablo fight one another in an action-strategy setting. Here's a brief description of the game from the press release.

Heroes of the Storm invites players to customize heroes to suit their style and then team up with friends for some all-out mayhem. The game features a variety of gameplay modes for players of every skill level, including Cooperative, in which players team up against computer-controlled opponents, and Quick Match, an accessible way to jump in and play versus others. Experienced players can also join forces against other teams of players in highly competitive, draft-style ranked play.

Heroes of the Storm will launch with more than 30 playable Heroes and 7 dynamic Battlegrounds, each with unique challenges to overcome—and even more Heroes and Battlegrounds are on the way. Players can customize the look of their Heroes with a variety of skins, as well as switch between a stable of special mounts that help them cover ground on the battlefield more quickly.
