Finished the final GDI Mission of Covert Operations.
This one is not as hard as NOD 11 but still quite challenging.
First you need to clear out two bases with the Commando.
As the mission starts 2 flame troops rush towards you, which you have to immediately take out in order not to get torched within a second.
Next, you have to attack the NOD base, which is quite well defended. If you are lucky this leaves you with your commando half in tact.
The biggest gripe with these commando missions is the enemies that spawn randomly after you destroy a building. They shoot immediately after the building explodes.
In this case you have to take out a turret, about 20 more soldiers and of course the 2 SAM sites.
Anyway, once you've cleared out the SAMs you get a few engineers to capture the buildings but you don't have any credits.
So next you have to sell a few buildings so you can train some infantry. Because all the way to the left is another heavily fortified base.
With a half dead commando and the little troops you can afford you have to capture that as well. The hard part here is an active Obelisk placed strategically above the entrance.
The solution is to walk over the Tiberium (which damages your troops), destroy 2 turrets and break the wall with a few rockets all while dodging the Obelisk (which in C&C has a crazy range).
Once that's done, again send in the Commando, kill the troops in the base and evade the Obelisk (and Harvester) to take out the remaining SAM sites. This unlocks the airstrike, so you can take out the Obelisk.
I had to do this part like 10 times, because every time the Harvester would run over my troops trying to take out the turrets and wall.
At that point you can capture the refinery for some credits and slowly train enough engineers to capture the rest of the base and destroy the remaining buildings.
Now comes the real mission. You're given 1 transport helicopter to move across an impassible river with your troops to capture yet another NOD outpost, which you need to take down two more bases,
One base keeps sending tanks, the other a large number of troops and even engineers to recapture your small and outgunned outpost. If the Commando is still alive at this point he'll likely be executed
by a helicopter which occasionally drops by to pick off your troops.
This was some intense shit
