Blizzard has just released the opening cinematic of the expansion of Starcraft 2, Heart of the Swarm, and it’s pretty awesome. The short, 3 minute flick depicts a full scale Zerg invasion of a human world, and is complete with transforming robots, massive explosions, tanks and creepy crawly Zerglings. Blizzard has always been a company that could make awesome cinematics, but we feel that the company has really outdone themselves this time around. If you want to view the entire thing as it was meant to be, click on full HD on the video below and be prepared to get blown away. Blizzard will be releasing the expansion on March 12, 2013.
