Walkthrough. All Bonus Objectives, Intel.
The build-a-Shredder/Laser Bonus Objectives can be a bit confusing in this one. It seemingly won't let us build one? Well, the answer is to build a War Factory, then an MCV, and THEN it lets us do it.
With regards to the mission, we build an extra Refinery for increase income speed, strike/capture a few things early-on while building our defences.
Then we train a wave of Flame Tanks n' Bikes, and go destroy stuff while training ANOTHER wave. The Flames are on point, and the Bikes serve as supporting fire and generally are used for handling enemy Predator Tanks.
Once the second wave is ready, we converge and finish the mission.
Best of luck!
