Hah, I always thought "Penultimate Assault" would be more apt, if not as cool.
I wrote once before whether if, in the very beginning, you knock out the enemy mech building the eastern turret, no nuke is built beyond it. That's wrong - its just timing as to whether another contructor is built.
Just finished this level for the zillionth time, and still as challenging. The AI is VERY aggressive and the scripting of this level likely more tight. I try to get that first aerial factory after the turret to avoid further attacks by air. This is best done with a Bee, but the heavy artillery next door can get you quick.
I just build judases. It seems to be the most effective challenge to the AI. I try - TRY - to save as many units as I can but once they send the first barrage of Bees over, you need that Judas badly. There's usually a tank or two headed your way too that you can grab.
The hardest thing for me is trying to worry about all this judasing while the AI is sending light and medium units straight north right at your base. I seem to never to rememember to spread out enough to deal. Another bee is what I use for the southern turret. Then it''s all just judasing and attrition.
There's a mek past the southern factories, if you judas him you MAY be able to capture the ion cannon. For some reason you cannot research it or steal the enemy's research....
There are triple rocket knights righ tthere so if you are good in FP you can really turn the tables right then.
Probably the best constructed Level. Now --- THE CONTROLLER! "Me on OTHER side now!"
