The Zerg reappear as a frequent menace, though Raynor ultimately recovers their incapacitated queen Sarah Kerrigan from the Zerg home world. Wings of Liberty is set four years after the events of StarCraft: Brood War, and focuses on the conflict between Jim Raynor's rebel faction and the Terran Dominion regime led by its emperor, Arcturus Mengsk. The story of StarCraft II continues on the story of the original StarCraft releases, dealing with the races of StarCraft and characters of StarCraft. Since 2017, StarCraft II multi-player mode, co-op mode and the first single-player campaign have been Free-to-play. StarCraft II multi-player gameplay spawned a separate e-sports competition that later drew interest from companies other than Blizzard, and attracted attention in South Korea and elsewhere, similar to the original StarCraft e-sports. A final campaign pack called StarCraft II: Nova Covert Ops was released in 2016. StarCraft II single-player campaign is split into three installments, each of which focuses on one of the three races: StarCraft II: Wings of Liberty (released 2010), Heart of the Swarm (2013) and Legacy of the Void (2015). Set in a fictional future, the game centers on a galactic struggle for dominance among the various fictional races of StarCraft. StarCraft II is a military science fiction video game created by Blizzard Entertainment as a sequel to the successful StarCraft video game released in 1998.
