Years after the events of End War, a new sentient robotic race called the Central Independent Systems (C.I.S.) entered and invaded the Korprulu Sector to strip mine the system's resources. With the Protoss being defenseless and assimilated by these cybernetic war machines, the Terrans and the Zerg must react quickly to a new threat. Which side will prevail?
As of Patch 1.1.2 it is now possible to dodge Tempest Projectiles by microing.
