In the distant future, a small group of human exiles have been doomed to fight for survival on the edge of the galaxy. Planet resources begin to run short, and three unique species--Terran, Protoss, and Zerg--engage in intergalactic warfare. As the military leader for your species, you must gather the resources you need to train and expand your forces and lead them to victory across three different campaigns. Each species has unique units, technologies, attributes, and abilities--all of which you'll need to master for control of the galaxy.
