Why settle for just one hugely impressive CGI trailer with little to no relation to the game its purportedly promoting? Here, have a second, courtesy of Blizzard, who have released the opening cinematic for Starcraft 2's first expansion, Heart of the Swarm. I have unofficially titled it: "Stompy, Stompy, Boom, Squish." There's a Wilhelm scream and everything. Enjoy.
As to what the expansion's story will contain, Blizzard say , "Sarah Kerrigan is on the loose. Even without the terrible powers of the Queen of Blades or the might of the Swarm at her command, the former Ghost remains a foe not to be taken lightly. But if the artifact really did set her free, then why is Kerrigan seeking out Zerg broods scattered throughout the Koprulu sector? Is she still pursuing her quest for vengeance, or has her transformation given Kerrigan a new purpose?"
Well, has it? Find out March 12, when Heart of the Swarm is released.
