Walkthrough. All bonus objectives, intel.
Another mission that CAN be really tough, but if you watch this video you'll learn a way to beat it easily!
First we take the Flame Tanks and go and destroy GDI's two smaller bases, their Airfield and War Factory, thus ending their production of aircraft and vehicles.
Meanwhile we're building up our base and defending against initial attacks.
We train a Commando and go and destroy the Barracks, thus completely putting a stop to GDI's unit production!
Then we start training a buncha Bikes.
We use the Commando and Bikes to clear a path to the Bonus Objective for our Saboteur. We capture Silos and Tiberium Spikes for a big boost to our moneys.
Finally we capture the Objective Building, park the Bikes at the Docks and let them annihilate GDIs reinforcements as they arrive. And we wait for "the Nerd" to be taken by the slowest transport ever (although at least it has decent Armour).
