For the first time since the demo was released, I destroyed the AGT. After that I continued purchasing vehicles and trying to pound the Weapons Factory. There were about 4 HOtwires in there so I could not do any damage. That was a bad idea.What I should have done was purchase a nuke, go thru the trenches while my team is pounding away in vehicles and place a nuke either right next to the Infantry barracks or Power Plant. If you can afford a stealth black hand then go behind the weapons factory and place it there.
Just sharing my experiences.
