StarCraft II: Wings of Liberty is a military science fiction real-time strategy video game developed and released by Blizzard Entertainment for Microsoft Windows and Mac OS X. A sequel to the award-winning 1998 video game StarCraft, the game was released worldwide on July 27, 2010. It is split into three installments: the base game with the subtitle Wings of Liberty, and two upcoming expansion packs, Heart of the Swarm and Legacy of the Void.
Set in the 26th century in a distant part of the Milky Way galaxy, the game revolves around three species: the Terrans, human exiles from Earth; the Zerg, a race of insectoids; and the Protoss, a species with vast mental powers. Wings of Liberty focuses on the Terrans, while the expansions Heart of the Swarm and Legacy of the Void will focus on the Zerg and Protoss, respectively. The game is set four years after the events of StarCraft: Brood War, and follows the exploits of Jim Raynor as he leads an insurgent group against the autocratic Terran Dominion. The game includes both new and returning characters and locations from the original game.
The game was met with very positive reviews from critics, receiving an aggregated score of 93% from Metacritic. Similar to its predecessor, StarCraft II was praised for its engaging gameplay, as well as its introduction of new features and improved storytelling, while criticism targeted features that existed in the original StarCraft game but were removed in StarCraft II, such as the lack of LAN play and the decision to split up multiplayer regions. In its first month on sale, StarCraft II sold a total of 3 million copies worldwide.
