This is one of the two missions in the second set where you have to choose between Amita and Sabal. Remember that choosing one over the other will lock you out of doing the latter’s mission.
As with the Balance of Power choice before, choosing Amita over Sabal will lock you out of being able to do Sabal’s mission. Amita wants you to take over the opium fields at the tea factory in order to fund the Golden Path. When you finally get there, scope out the place with your camera and tag as many enemies as you can find.
In addition to the normal enemies, there will also be a few dogs in the compound. It’s best to make your way to the building in the center, especially if you’re going to start going crazy, as the building will help you in filtering the enemies one by one. There are a few alarms in the compound, so it might be wise to disable them before doing anything else.
Once you manage to initially clear the place, do not meet up with the fellow Golden Path members. Instead, go around and find some machines that, when interacted with, will activate the sprinkler system on a nearby field. Now, go meet up with the Golden Path and enemies will start spawning from the south. The regular enemies won’t be the problem here, but ones that throw Molotovs will also appear among them.
It’s not important to save every single field, as losing one or two of them will still allow you to pass the mission.
If you have already guessed, the enemies’ main goal here is to burn down the fields, which is why it is important to know where the sprinkler generators are located. Also, it’s important to recognize the Molotov enemies from the others, making sure you shoot them until you get XP (which means they’re dead). After the south, they will come from the east and then the north. Once all enemies are dead, the mission will end.
