You are Sarah Kerrigan, former Queen of Blades. Once the most feared entity in the galaxy, you now wait in a cell in the depths of a high-security research laboratory. Before the murderous forces of the Terran Dominion close in, you must plot your escape to the dark reaches of space and reclaim your living empire at the Heart of the Swarm. Over the course of the campaign, you will grow in strength and earn new abilities, and must choose which powers to enhance and use from mission to mission.
Note: This is an expansion pack and requires StarCraft II: Wings of Liberty to play.
