Picking up after the events of StarCraft II: Wings of Liberty and the first expansion, Heart of the Swarm, Legacy of the Void is focused on the Protoss species as they launch a full-scale assault on their former homeworld of Aiur. The planet was lost to the Zerg in the original StarCraft and the Protoss have been planning to retake it every since. The game will focus on Executor Artanis, one of the heroes of the original StarCraft expansion, Brood War, and on his flagship, the Spear of Adun, which will form the hub area between game missions.
As is usual with Blizzard, no release date has been set. However, with the game set to enter beta shortly, a 2015 release is possible.
Meanwhile, Blizzard have also announced their new game Overwatch. This is the first new IP that Blizzard have created in seventeen years and focuses on super-powered heroes and villains fighting on a futuristic Earth. The game will be a team-based FPS and bears more than a slight resemblance to Valve's Team Fortress 2. It looks like the game is drawing on assets and lore created for Blizzard's cancelled MMO shooter, Titan.
