Blizzard has released Legacy of the Void, the latest and final expansion for StarCraft II, and is already enjoying great sales. In the first 24 hours of release they had already sold a million copies.
The Legacy of the Void expansion focuses on the Protoss faction. The Protoss are trying to reclaim their homeworld but also dealing an ancient evil that is hell-bent on their destruction. The Protoss are the final faction that needed a storyline campaign so no further big expansions are in the works. However, Blizzard has said they will be featuring storyline mission packs for StarCraft 2 to keep the story going.
