Today Blizzard released a short teaser for StarCraft II: Heart of the Swarm, the upcoming expansion to StarCraft II: Wings of Liberty. While it doesn’t show any actual in-game footage, it does provide some hints as to where the single-player story is headed.
While no official release date has been announced, rumor has it that it will be released around April 2012. Heart of the Swarm will add additional units to the multiplayer game mode, which will cause some massive changes to the current SC2 metagame.
