Blizard Entertainment has released several new screenshots from Starcraft 2, illustrating the upcoming sequel to one of the most popular RTS games ever released. 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. StarCraft II will also feature a custom 3D-graphics engine with realistic physics and the ability to render several large, highly detailed units and massive armies on-screen simultaneously. StarCraft II will include a unique single-player campaign, as well as fast-paced online play through an upgraded version of Blizzard's Battle.net. In addition, the game will come with a powerful, full-featured map editor that will put the same tools used by Blizzard's designers into the hands of players. A new StarCraft II Q&A can be found here.
