Set in the 26th century in a distant part of the Milky Way galaxy, the game is built around three species: the Terrans, human exiles from Earth the Zerg, a race of insectoids and the Protoss, a species with vast psionic power.

The decision was taken to provide more breadth to develop the game's story. Initially conceived as a single game, StarCraft II was split during development into three installments: the base game which acquired the subtitle "Wings of Liberty", and two expansion packs, Heart of the Swarm and Legacy of the Void. The game was released on Microsoft Windows and Mac OS X. StarCraft II: Wings of Liberty is a military science fiction real-time strategy video game developed by Blizzard Entertainment as a sequel to the award-winning 1998 video game StarCraft.
