Walkthrough, hard. All bonus objectives, intel.
The game is Command & Conquer 3: Kane's Wrath. The mission is Will Made Flesh, on Hard mode.
I think this one can be tough, the Blue Tib runs out quick, the green Tib fields are far away. And you can end up losing the very strike force you're building up, trying to defend your own base!
So, a different approach is needed.
Train an Emmissary and Black Hands, tech up. Then go park on GDI's Southern doorstep. Then we can claim a second Blue Tib field, AND a Green one, fire up Obelisks for defense.
Construct a Redeemer, backed up by Specters and SLOWLY advance on the GDI base, falling back for repairs if needed.
Once we reach the second half of the GDI base, we send in Raiders for AA backup, and then proceed to finish off most of GDI's forces.
Capture the four Nodes, then while we're waiting for the countdown, mop up with some Scorpions and Raiders.
Mission accomplished!
