StarCraft II - Wings of Liberty continues the epic war saga of the Protoss, Terran and Zerg. These 3 distinct and powerful races will clash once again in the fast-paced real-time strategy sequel to the legendary original, StarCraft. Legions of veteran, upgraded, and brand-new unit types will do battle across the galaxy as each faction struggles for survival and/or dominance over the others. Wings of Liberty features a unique single-player campaign that picks up where StarCraft - Brood War left off, and tells about the consequences and aftermath of what transpired from the Terran perspective. SC II - Wings of Liberty presents a cast of new heroes as well as a few familiar faces in the sequel to this edgy sci-fi saga filled with adventure and intrigue. In addition, Blizzard once again offers exciting online play through Battle.net, its world-renowned gaming service, with several enhancements and new features that'll make SC II just as much of an incredible competitive and enjoyable real-time strategy gaming experience as the original.
