The Queen of Blades no longer exists and Sarah Kerrigan has been restored to her human form. The Swarm is without a leader, scattered into several broods throughout the Koprulu sector. Yet all is not well. The artifact Jim Raynor used may have set Kerrigan free, but she still seems bent on assembling the Zerg broods, even without the terrible powers of the Queen of Blades. Is vengeance still on her mind? Or does Sarah Kerrigan have a new purpose? Will she be able to restore her strength and regain control of the Swarm? Or will Emperor Arcturus Mengsk finally be able to take out his weakened enemy?Help Kerrigan fight her way through an expansive single-player campaign in StarCraft II: Heart of the Swarm. Travel to some of the most dangerous worlds of the Koprulu sector, including Char, where a rogue queen is gathering eggs laid by the former Queen of Blades to hatch as her own, and Kaldir, a frozen planet that will require Kerrigan to adapt to the withering cold as she tries to find out what happened to her lost brood. Unlock new roles and acquire new abilities as you progress through the campaign. Mutate your zerg species in between missions to create a better, faster and stronger Swarm and explore new multiplayer maps with new units as you try to lead the Swarm to ultimate victory.
