Description & requirements
Heart of the Swarm is the first expansion set to Blizzard Entertainment’s sci-fi real time strategy game, StarCraft II: Wings of Liberty. Heart of the Swarm continues the epic story from Wings of Liberty with an all-new campaign that focuses on Kerrigan, the erstwhile Queen of Blades. New multiplayer content will also be included in the expansion, as well as new features and upgrades to the Battle.net online platform. Heart of the Swarm’s campaign will include approximately 20 new missions. Players will be able to evolve their swarms with unique, campaign-only units and abilities, and this evolution will happen in an organic manner befitting of the expansion’s zerg theme. As an example, zerglings can be induced to evolve the ability to split into broodlings upon death. Further evolution can yield specialized sub-species of zerglings such as the swarmling, a variant that spawns three swarmlings per larvae instead of the standard two zerglings.
