Blizzard has announced a 24-hour global broadcast for the launch of StarCraft II: Heart of the Swarm as it releases around the world on the 12th of March.

The official celebrations will start in Melbourne’s Federation Square, then circumnavigate the globe before finishing near Blizzard’s headquarters in Irvine, California.

"Top StarCraft II pro-gamers will play Heart of the Swarm show matches with your favorite casters narrating the action," writes Blizzard. "We'll also feature live demonstrations of new features in Heart of the Swarm, showcase videos and community content, and give away great prizes."

Developers will also be present at the official events to sign copies and answer fan questions, says Blizzard.
