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?
The third map in the campaign is harder than the previous two missions, because you have to endure both the C.I.S. forces hacked by Nova's forces. The objectives are not beginner friendly, as it forces the player to stay safe:
1. Destroy the Control Ships, as Alpha One cannot restore them
2. Send the Protecate (hero unit) to the Megacortex
3. Hold off for 3 minutes (1 minute for first Megacortex)
4. Repeat for the second and third Control Ships and Megacortexes.
5. Destroy Nova's Command Center.
You also have to not kill or lose 3 Bastions, owned or not because the C.I.S. needs them for the grand invasion plan, and Nova's Ghosts which can Lockdown all of your units and nuke your base frequently.
The map takes place on planet Tyrador VII, the darkest, coldest planet in the Tyrador system, and is set four months after the second mission. This mission is the first time the player uses Raptors, which are very powerful against large air units including the Control Ships.
