This page provides a walkthrough for the first part of the eighth chapter of Uncharted: The Lost Legacy - "Partners". In this chapter, there is a lot of climbing and exploring, but there are no demanding puzzles here. Also, you will have to fight Shoreline mercenaries and the difficult part here is that you cannot start the fight in hiding.
Right after the chapter starts, take a few steps ahead and wait for the icon of optional conversation (1/4) to appear over Sam's head. Interact with him.
Additionally, check out the ledge on the left shown in the above screenshot. You can jump towards the ledge, or get there by lowering yourself by the edge to find treasure (1/8 -Jeweled Snuff Bottle). After you have collected it, return to the starting point.
Follow the linear path, where you will slide over slippery ground, jump onto ledges below,, walk over a fallen tree trunk next to a small waterfall and squeeze through a small cave. Along your way, you will notice an enemy chopper for the first time, but you will fight it much later.
Stop after you reach a larger waterfall, where you can jump into water. Dive here to find a treasure (2/8 - Brass Ewer) at the bottom shown in the above screenshot. After you have obtained it, jump towards the opening above to enter a larger cave.
Cross the cave and stop in the spot shown in the above screenshot. Jump onto the muddy ground to slide down. During the ride, note the ledges on the left. Jump towards them at the right moment and climb up (you will have to use the hatchet). Here, you will find another treasure (3/8 -Mamluk Brass Bowl). Additionally, you can jump down into a tank below to obtain a trophy - Cannonball!.
Return to the cave entrance and after you start sliding down, jump towards the ledge on the right. Climb up to continue. You will recognize the path by the necessity to squeeze through roots in a narrow passage.
Soon, you will start another uncontrollable slide down. Be prepared to use hook and rope to avoid falling down. Swing on the rope and jump towards the three green ledges (grab any of them). You will soon be joined by Nadine and, before you continue, wait for the opportunity to have with her an optional conversation (2/4).
Reach the location with fence neighboring a waterfall, shown in the above screenshot. Check out the dark corner, where there is treasure (4/8 - Crescent Flask). After you have collected it, approach the fence and jump over it (to the external side). Note the metal elements above thanks to which you can continue climbing and reach railway tracks.
Take interest in the platform on the rails that you have to push towards the damaged fragment of the tracks, where there is Sam. See the cutscene, during which Sam will rejoin you. Wait for the opportunity to have with Sam another optional conversation (3/4).
Find a wall with a ladder on top of it and stand in at the wall to give Nadine a boost up. After Sam and Nadine get up, climb onto the pipe to join them.
Approach the metal post next to the tracks, jump towards it and move right. Turn by 180 degrees and climb over the projecting metal elements. While climbing, you will have to use hook and rope on the hook by the tree.
Chloe will soon fall down and, while sliding down over ledges, you gave to jump at the right moments to avoid falling into the chasm.
After you have landed on a stable ledge, go left. Reach the small green ledges shown in the above screenshot. Start climbing over them to reach a small cache with treasure (5/8 -Soapstone Jewelry Box).
Return now to the ledge where you have landed after the downslide. Go right, wait for the rope to be extended and press X to reach it. Climb over it enough to be able to reach the opening next to the waterfall.
You will watch a short cutscene and learn that you have reached a location occupied by Shoreline mercenaries. You cannot sneak here, because Nadine will dart towards them to kill them.
The most important thing in this fight is to obtain a decent weapon, e.g. S-12 shotgun. Later on, you can swap it for the automatic shotgun (one of the gold weapons) used by heavy opponents. Regardless of what weapon you are using, try to change your positions often, although you can, e.g. stick to Sam and eliminate opponents with cooperation takedowns. apart from that, note the numerous gas cylinders around that you can blow up. In total, there are two waves to defeat (the other wave arrives after some time into the fight).
After the fight, reach the collapsed cave exit. Stop next to Nadine and wait for the icon to appear over her head, thanks to which you can have an optional conversation (4/4) with her. After that, examine the collapsed passage, thanks to which you will remove a large beam and leave.
Right5 after that, you will start sliding down. wait for the moment at which to use the hook and rope. After the jump, you will have to slide down some more, with more jumps afterwards.
After the last jump, you will get to a vertical wall over which you have to climb (you will have to use the hatchet here). After you have reached a new ledge, find the camera icon because this is an photo opportunity location (1/1) (the object to photograph are railway tracks in the distance with railway cars on them).
Around, there also is another collectible, shown in the above screenshot. You cannot get there by taking a simple jump and you have to climb over the cliff face and over ledges. Thanks to this, you will reach safely the ledge with treasure (6/8 -Peacock Nut Cutter).
Grab on to the green ledges on the cliff wall and climb up. You have to reach the spot shown in the above screenshot, where you can use hook and rope on the metal structure by Sam and Nadine. Soon, the structure will partially collapse and you have to hold down L1 to start climbing up over the rope.
After you have joined your friends, explore the area with railway tracks. There is a new platform here and start pushing it with Nadine.
Keep pushing the platform over to the collapsed passage. After you do that, walk away and interact with the switch here. Then, approach the platform and start pushing it the other way, towards the wall at the other end of the track.
The platform will build up speed and hit the wall. The wall will collapse. Thanks to this, you will be able to get to the other side of the barricade. Here, you will find a ladder, where Chloe and Nadine have to give Sam a boost up.
You can now remain in the cave and hear the conversation out, or head into the previous location *the one with the tracks). Here, you have to push the platform back into its initial position. Just like earlier, interact with the switch at the right moment to have the platform roll on the tracks to the right. Sam will drop down a crate onto the platform (the above screenshot) and use it to climb up.
After you join Sam, head left and explore this part of the cave into which you have given Sam a boost up earlier. Here, you will find treasure (7/8 - British Powder Flask).
Return to Sam and Nadine, and go right of where you have climbed before. Climb over the wall to get to the ledge up above. A bit ahead, there is a hook. After you grapple the hook, turn around, while hanging down, by 180 degrees and swing towards the small ledge shown in the above screenshot. By jumping there (you have to be precise, or you will fall down) you will be able to obtain treasure (8/8 - Strange Skull). Examine it in the inventory straight away, because this is an unique artifact and you can obtain a trophy - Shake for Your Fortune.
Again, use hook and rope to reach the buildings by the tracks. Reach one of the ajar windows to watch another cutscene.
