Varshakot | Fortresses Far Cry 4 Guide
Last update: 11 May 2016
Attack this fortress after you've completed the City of Pain mission. It will make it easier for you, as there will be 2 alarm boxes, not 3, in the area. There will also be less enemies. It is good to have a grenade launcher or the Heavy Takedown skill and a Guns for Hire token. Think about a new bow and don't forget to take enough ammo. By doing so, you will be fully prepared to start the task.
Start from the south. To the left of the gate, you will notice a grappling point. When on top, kill the sniper standing there. If you have a good bow and a steady hand, kill another sniper standing on the other side. Do it from the building below (while standing on the edge). Along the wall, head to the north gate and jump outside. Sneak through the gate (watch out for the dog) and turn left, behind a building. Walk straight, up the stairs and you will reach one of the alarm boxes, which you should of course deactivate. If you haven't killed the second sniper, go up and do it now
Jump down onto a smaller building, from where you will have a good view on the central part of the square. Notice (and destroy) the second alarm box. You don't have to worry about reinforcements anymore. Now, it is a good moment to summon a mercenary, using the Guns for Hire token. He will make some noise and distract the enemies. Help him by shooting the opponents from behind a cover. The hardest part is defeating the heavy gunners. Do it using takedown (if you have the appropriate skill) or a grenade launcher. Two grenades thrown at them should also do the trick. Leave the armored soldiers for the end, as they are the biggest threat for you.
To sum up: first, deal with the snipers, then, destroy the alarms. This will make it easy to eliminate the rest of enemies. Distract them by hiring a mercenary and kill the soldiers from above. The easiest way to deal with the heavy gunners is to use a grenade launcher or simply throw grenades.
After capturing the fortress, your outposts in this area won't be attacked anymore. You will also not encounter any enemies.
