Blizzard’s entry in the MOBA genre, Heroes of the Storm, is now live.

The game is free to download from the official site on Windows PC and Mac.

In Heroes of the Storm, players form teams of five heroes or villains from Blizzard’s different game universes, including Warcraft, StarCraft, and Diablo, and battle other teams for glory in the Nexus.

According to Blizzard, there are a wide range of options for customising how heroes look and play, with different abilities, skins, and mounts available.

The game currently has 37 playable heroes and seven battlegrounds, and more of both are on the way.

It also features multiple gameplay modes including cooperative versus AI, quick match, and draft-style ranked play.

In celebration of the game’s launch, players who enter the Nexus within the first week (June 3–9) will receive a special in-game portrait. Players will also receive XP boosts during the first three weeks of launch.

“Nowhere else can you find your favourite heroes and villains from different Blizzard games teaming up and duking it out in short, action-packed battles,” said Blizzard CEO Mike Morhaime.

“Players battled each other in over 100 million matches during testing, and we saw tons of surprising strategies and insane last-minute wins—we can’t wait to see what else players come up with now that Heroes of the Storm is officially live.”

Everyone is invited to tune in to the Heroes of the Storm YouTube channel Saturday, June 7, from 7am–8 am NZT for a special online event – Heroes of the Storm: The Mayhem Begins.

Live-streamed from the YouTube studios in Los Angeles, the event will include a sneak peek at never-before-seen content presented by members of the development team, as well as showmatches featuring Jesse Cox, Cloud9, and the reigning Heroes of the Dorm champions, UC Berkeley.

Heroes of the Storm is also launching with a Road to BlizzCon eSports tournament, featuring competition spanning the Americas (including Australia and New Zealand), Europe, China, South Korea, and Taiwan.

More than US$1.2 million is up for grabs, and the top eight teams will face off at BlizzCon on November 6–7 in Anaheim, California.
