Shut down the oil transfer pump and destroy the oily water separator tank
The oil transfer pump will be marked on your map and is in a room at the top of the large building at the oilfield.
Hit the switch on the central terminal to complete the objective. It’s recommended that you do this before you destroy the oily water separator tank because soon as the tank is destroyed, the oilfield will go into lockdown and soldiers outfitted with Walkers will head in to seal off the area.
You’ll find the tank at the opposite end to the entrance. As soon as it’s destroyed, the alarm will go off and soldiers with Walkers will head your way to seal off the oilfeld.
Exfiltrate the hot zone before Mfinda Oilfield is sealed off
If you take out all of the soldiers and destroy the anti-air radar, you can have the helicopter pick you up from the front entrance as soon as you set off the C4, exfiltrating the hot zone before the oilfield is sealed off.
Extract 4 Walker Gears sealing off Mfinda Oilfield
After you destroy the tank, the soldiers and Walkers will move in to seal off the oilfield. Find a strategic spot to take them down from as they head in. A vantage point high up will be the most effective.
Extract the lappet-faced vulture that wandered into the burned-down village
The vulture will be in the burned village, marked on the map above.
If you’re lucky, it’ll land on one of the buildings in front of you as you enter the area. Tranquilise and extract it to complete the objective.
Extract 4 child soldiers being trained at Masa Village
Use your int-scope to locate the children at the village. Tranquilise and extract them. An efficient way to do this is to put them in the vehicle at the village and fulton extract it.
