Let the zerg rushing begin. StarCraft II's first expansion comes out tomorrow. Blizzard is celebrating by streaming StarCrafty things all day.
The Heart of the Swarm global launch event, which you can watch using the embedded stream below, is hosted by the much-beloved Sean "day9" Plott. It will take a look at the worldwide SC2 launch parties, from Australia, to South Korea, to California.
There will also be a "King of the Beta" tournament and some fanmade videos, Blizzard says. The stream will end when the game launches at midnight Pacific tonight.
