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?
Terran:
Spectre - Advanced anti vehicle unit. Requires Academy and Armory.
Pulverizer Tank - A heavy tank designed to soak enough damage. Requires attached machine shop and physics lab.
Banshee - Aerial cloaked unit now does AoE damage to ground units. Requires attached control tower.
Zerg:
Scorpalisk: When Zerglings and Hydralisks aren't enough, Scorpalisks come in for anti-armor. Requires Lair.
