At the end of Chapter 12, we found the clue where Avery’s Statue is pointing at which is none other than Libertalia. Soon after the short Prolog cutscene you will find Nathan all by himself on a Mysterious island where he needs to look for his Brother Sam and continue with the adventure.
After the cutscene, you will find yourself on the beach so start walking straight and the first thing to do is climb up high to know where you are exactly. As it is heavily raining you will have no idea where to go exactly and you will also find Nathan a bit exhausted. So head towards the slope and take right, keep walking on the log then climb the hill on your left.
You will find on the other side of the shore wit ha supply box near which is empty. Get inside the and follow the cliff to climb up to the next level and as we said the rocky are wet so Nathan will be pretty slow to act like jump and climb. Keep moving forwards and work around until you drop into a pool of water.
After the cutscene, you will find all the weather is clear and Nathan has recovered himself from a long terrible boat and cliff crash. You will have multiple options to get towards the mountain, but we prefer to use the Waterfall path where you need to climb and use the Grapple hook.
There will be a couple of near fall moments, but you will eventually make to the higher ground. Soon you will find a Green part of the cave inside the Waterfall area and again continue your climb where you see the Skeleton hanging around. As you reach towards the skeleton you will get a new item to use which is the Piton, you can use this to Jab on the porous surface.
Soon you will encounter the Shoreline enemies up ahead and we prefer you to take them out the Stealthy way as there are Dozens of them where one is hiding at the top of the tree and the other has the Grenade Launcher. After taking them down keep following the cliff and start climbing on the right where you find the Journal Notes.
Once you reunite with Sam follow him into the woods to get some more clues of the pirate symbols. Soon you will reach a large wall with a shack, so climb up and enter from the roof into the hole and make your way to climb up back to the other side if the abandoned building. Use the Ramp to your left then you will come out into a small room.
Throw the Container down to climb up with Sam and thus completing the 13th Chapter of Uncharted 4 Thief’s End and you can either continue to the next Chapter 14 – Join Me in Paradise or check out our Uncharted 4 Wiki Page for treasure, journals locations and Much more.
