Aegus...Empyrrean's Guardian is the 21st mission in the CORE campaign, set on Empyrrean's moon, Aegus.
The Core has reached Aegus, a small low-gravity moon orbiting the ARM homeworld of Empyrrean. Before they begin the final attack on Empyrrean, the Core must secure the moon so that they may use it as a staging ground for the invasion.
- Capture the Galactic Gate
This mission is a race against the clock, since you have only a small window of time to capture the gate before it implodes. You have a large battalion of tanks and KBots and a well-defended ARM outpost standing between them and the Gate. Don't waste time assembling a base. Gather your forces and blast your way through the ARM defenses to reach the gate.
