Lovely new area. Take a look around. There’s a hidden tomb you can’t open yet, until you have a new piece of gear. Look for salvage, the caches that are this level’s collectible, the GPS thignees, etc, before you head over to the marker.
After you get your mission, head across the bay on the dock bridge, climb up the rigging, then move to the galleon. Inside, you can get the drop on some bad guys. Head up to the top of the ship and shoot an arrow at the anchor to get your quest item. Three more guys will be between you and the rope slide to turn your stuff in.
After you get an upgraded bow, follow the path, do some jumping, and you’ll wind up taking a much more precarious trail out across the bay. Look for the white points to jump to, expect a couple of dudes, and you won’t be surprised.
The next secret tomb will be directly on your way. It’s in a bunker to your left, marked with drawings. If you only go for one of these in the game, make it this one. There’s a relic and all sorts of goodies on the way. This is The Flooded Vault. Head in, hit the power switch up top, then the one downstairs to open the doors. Look at the raft on the left, and shoot the bound-up bundle wrapped in white cloth with fire. Then head to the opening on the right, blow out the shotgun wall, and bring the raft to you via the rope arrow. Use the raft to jump around to the next section. From there, pull the thing in the ceiling down with a rope arrow. The second you do, cross the water to the other section before the power comes back on. Draw the raft next to the battery in the water. Then raise it, pull the raft under it, and travel safely in the water. Head upstairs and then exit with your prize.
After the tomb, the path to continue is pretty straightforward, jump to a mast, crawl through a tunnel… Grapple and cross over to the bunker and then enter it. You’ll face a coterie of guys. Snipe as many as you can, prepare for an aggressive swordsman, and you’ll be fine.
As you move on, you’ll grapple up a small tower, and fight off a small flight of guys. No problem. As you come out into the daylight, with the setting sun before you. Head off the ledge, shoot a rope across, and then move along to the Endurance.
Once you hit the deck, there’ll be a couple of guys, but your main issue will be the giant armored dude. Hit him with bullets while you can, but mostly you’ll wanna dodge and stab. He’ll give you a new piece of equipment that’ll come in handy immediately.
In the next section, you need to combine jumping on the hook set in the roof with hauling it around by rope shot to get it under the hole in the roof. Pull it toward Alex, then move it to the right. Then move it back toward where you started, then slide it to the left, under the hole.
Then, move the hook back toward where you started, then move it to the right to line it up with Alex. Then pull it toward him. Then pull it away from him.
Back on land, pull the block off the ledge with your new widget. On the way back, look for another rope to ascend to backtrack. At the top will be three guards. Take them out, then take the rope down to base.
Now that you have the rope pulley, you can open the door to the tomb on the beach. This tomb is the Temple of the Handmaidens. Raise the platform with the crank and watch the buoy float. Run up to the upper level, and grab the pole and swing across when the buoy moves it. Shoot the rope point on the next tower to pull it in front of the buoy so you can jump across to that pole and then across to the climbing wall.
When you’re ready to move on, go to the elevator, climb up the shaft, and then shoot a rope arrow across to the climbing wall on the tower. Then, find a concrete post, use it to jump to the water tower, and then jump off that to the ladder to get all the way to the top.
Pull one gondola to you with the rope, jump on it. Pull the second one to you, and get ready to jump onto it and then immediately off again. Move on, look for a rail that will take you up to a climbing wall and continue your ascent.
On the next platform you’ll face two guys, then two more. Once they’re out of the way, you’ll hop up, and then use a rope bridge to continue. Across the way, you’ll make a faith jump, and then use the pulley to open another door.
