Blizzard have released a new gameplay movie for StarCraft II, the hugely anticipated RTS expected to be released at some stage in 2009.

Designed to be the ultimate competitive real-time strategy game, StarCraft II will feature the return of the Protoss, Terran, and Zerg races, overhauled and re-imagined with Blizzard’s signature approach to game balance. Each race will be further distinguished from the others, with several new units and new gameplay mechanics, as well as new abilities for some of the classic StarCraft units that will be making a reappearance in the game.
