The Valley of Death | Main Quests Far Cry 4 Guide
Last update: 11 May 2016
You will obtain this mission only if you've supported Amita during the last choice (the Culture Wars mission).
The fastest way to reach to place is to use the buzzer (watch out not to fly straight between the batteries - you should land a bit earlier).
Near the first cannon, you have to eliminate four enemies. The leaders are marked with yellow color and they are responsible for shooting, so if the town endurance bare will be dangerously low, you will have to eliminate them first. Try not to be noticed at this stage of the mission - you can simply destroy the alarm box. After eliminating all the enemies, head towards the village.
Watch out for the sniper located on the watchtower. You will find the next cannon around the tower - head right when after you enter the village. Here, you also have to kill all the enemies. You can do that easily by standing on the roof of the building that you see when on the way. If you don't want to have enemy reinforcements all over you, destroy the alarm box before starting the fight or eliminate all the enemies silently. The third and the last cannon is located in the highest part of the village. The strategy here is the same - watch out for another sniper. After killing all the enemies, you will receive a new objective.
Protect the sappers
There is a vehicle heading your way, with two sappers inside. You have to protect them. Go onto the tower and grab your grenade launcher. Omit the first car and then get ready for three jeeps full of enemies. From this position, you should have no trouble aiming at them. Destroy them before the soldiers get out. After a while, the sappers will plant explosives near the first cannon.
With your allies, head to the second cannon. If you have the appropriate weapon, you can shoot down the helicopter heading this way. When you do that quickly enough, you will make the task much easier for yourself, as you will kill several enemies at once. When the sappers are planting explosives, watch out for another wave of enemies - you can use the MMG located here. After the cannon explodes, head to the third cannon. Clear the area again so that your allies could plant the bomb. Watch out for the enemies that shoot at the when they do that. After the explosion, you will complete the mission.
During the mission, remember not to stand to close to the cannons after the bombs are planted (you will notice a countdown starting when it happens). It may so happen that both sappers get killed. In such case, pick up the bag with explosives and plant them yourself.
