Vaas is preparing weapons to attack Amanaki, and Dennis and the Rakyat want you to take out their weapons cache. The Logging Camp is south and a little east of Amanaki Village (there’s a Radio Tower southwest of it, so go and get that first). Be careful of wild animals, especially any tigers, as you run through and towards the camp.
When you get to the area where the camp is, you will need to go to the vantage point next. Take out your camera and try and tag as many enemies as possible (there are at least 7). Once you got enough, you will need to get into the camp and disable the alarm. There is one guy sitting down between the two fences straight ahead from the vantage point, so sneak up and use a Takedown on him.
Once you’ve gotten inside the camp, you need to be careful of the two enemies to your left, as well as the one on the docks. Continue sneaking until you get to the alarm, then hold the button in to disable it. After doing that, it’s time to get into the weapons cache, which is the building right by you.
Enter through the door, then plant the bomb at the designated spot. You now have 15 seconds to escape and get to a safe spot. Once the cache blows up, you can either escape or stay and kill all of the pirates. Whichever you do, the mission will be over and Dennis will call you, leading to the next mission.
