During the Starcraft II World Championship Series last weekend, developers Blizzard took the opportunity to unveil both a spectacular opening trailer and the release date for the third and final chapter of the SCII trilogy, Legacy of the Void.

This time the game revolves around the technologically advanced Protoss race and features the alien leader's giant flagship, The Spear of Adun, as Legacy of the Void's hub. The trailer shows a battle between the Protoss and the Zerg, as the former attempt to reclaim their homeworld from the swarming menace.

The expansion will tie up Starcraft II's story, revealing the fates of Jim Raynor and Zerg Queen Kerrigan. The game will also introduce the new Archon mode, which allows two players to share control over a single base and battle against an opposing pair of combatants. Another new feature is the Allied Commanders mode, which brings more RPG elements to the game and adds objective-based co-op missions.

Blizzard revealed that Legacy of the Void will be released on November 10th this year. A pretty brave date to choose, seeing as it's the same day both Rise of the Tomb Raider and Fallout 4 are being released.

Legacy of the Void can be pre-ordered now at a price of $40 for the standard version. There's also a $60 'deluxe' edition that offers a few extra goodies like new unit skins and bonuses for other Blizzard games such as Heroes of the Storm. Anyone who does decide to preorder will get immediate access to the Legacy of the Void beta, which lets players try the three 'Whispers of Oblivion' prologue missions.

Once the king of the eSports scene, Starcraft II and its expansions have lost ground in recent years to the likes of Dota 2 and League of Legends. Blizzard will likely be hoping that Legacy of the Void and its new multiplayer game modes will give the series a boost in popularity, and remind people what makes Starcraft such a fantastic multiplayer title.
