Blizzard is hoping to push the first StarCraft 2 expansion, Heart of the Swarm, out the door during the first half of 2013. Blizzard head Mike Morhaime made the announcement during Activision's earnings call, saying the studio is "working hard towards a first half 2013 launch."
Heart of the Swarm is set to add several improvements to StarCraft 2, including multiplayer progression and new social features.
On Tarsonis, Sarah Kerrigan was betrayed by her allies and left to die by the people she trusted most — but she survived, twisted by the terrifying zerg Overmind. As the Queen of Blades, she controlled the voracious zerg Swarm in a campaign of vengeance and retribution with a deathtoll numbering in the billions. Now, with her powers stripped and her mind finally free from the zerg influence, how much is really left of the woman who once was Sarah Kerrigan? Can her human side be redeemed... or does Kerrigan’s fate forever lie within the Heart of the Swarm?
