StarCraft II: Heart of the Swarm Preview Trailer

This 2013 standalone Real-Time Strategy expansion focuses entirely on the Zerg campaign, playable without the base game. You command Sarah Kerrigan, the former Queen of Blades, as she seeks vengeance and reclaims the Swarm. Core gameplay involves RTS base management combined with a deep Zerg Evolution System, allowing permanent customization of unit types. Kerrigan functions as a powerful hero unit whose abilities are upgraded throughout the narrative, which explores Zerg origins and culminates in the final confrontation with the Terran Dominion.
