The single-player campaign features an even number of missions similar to Wings of Liberty and Heart of the Swarm and centers around the Protoss character Artanis, hierarch of the Khalai Protoss and the Nerazim (Dark Templar). Pre-ordering the game granted immediate access to the multiplayer beta and a set of three prologue missions titled Whispers of Oblivion, which were subsequently made available to all players following the Heart of the Swarm 3.0 update on October 6, 2015. The pre-order of the game was announced and made available for purchase on and major game retailers on July 15, 2015. The testing closed on November 2, 2015, a week before the November 10 release date. Blizzard launched its invite-only beta testing of the game on March 31, 2015.
The campaign, which focuses on Artanis as its protagonist, is a sequel to Wings of Liberty and Heart of the Swarm, and concludes the StarCraft II trilogy. The expansion includes additional units and multiplayer changes from StarCraft II: Heart of the Swarm, as well as a continuing campaign focusing on the Protoss race. The game was released on November 10, 2015. StarCraft II: Legacy of the Void is a standalone expansion pack to the military science fiction real-time strategy game StarCraft II: Wings of Liberty, and the third and final part of the StarCraft II trilogy developed by Blizzard Entertainment.
