Walkthrough. All Bonus Objectives, Intel.
We get to use some fully promoted units in this one. They've got some firepower, and the self repair ability. Nice!
The mission itself is a bit of a puzzle. Especially if you want the bonus objectives. Once you know the right order, the mission becomes much easier.
In this walkthrough, we knock over the tiberium crystal/prism thing. Then we sneak across the North of the map and capture GDI's refinery.
After this, we head south, capture the barracks and Bonus Objective building.
Train a buncha missile squads. Then we go after the trucks (with a bit of a specific strategy), and finally return to base for the final showdown with the Scrin.
Well, I call it a showdown, but it's more like them sending a gazillion units at us while we prey we survive long enough for the Carry-Alls to arrive. xD
Fortunately we survive perfectly fine, with plenty of units to spare.
Phew!
