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. 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. In addition to its unique single-player campaign and fast-paced online play, 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.
