At Sea

Marco Polo Returns! Trophy: At the start of Chapter 12, you'll be in a boat. To the left of the large island ahead, find a smaller island with a wrecked ship. Enter the water in either of the two inlets on this smaller island. Nathan will shout "Marco!", Sam will reply, and the trophy will pop.

Persian Leather Notebook Case: Head back toward the large island and follow the coast left until you reach a part of the island that juts out, forming two arches. Sail under them. Just past this is a ledge on the island's side. Park the boat next to it and climb onto the hood to reach the ledge. The Persian Leather Notebook Case is at the top.

On Porpoise Trophy: On the north side of the islands, drive the boat near dolphins to get them to follow. One dolphin is near the island with the wrecked ship. Another is between that island and a set of three rocks near the big island. Get three dolphins to follow the boat for the trophy.

Panamanian Pendant: On the north side of the other island, find a very small beach section to collect the Panamanian Pendant.

Persian Silver Pen Box, Journal Entry, Silver and Wood Tankard: Continue around to a larger beach. On the far left side is a cave containing the Persian Silver Pen Box. Further inland, examine a skeleton tied to a large pole for a Journal Entry. Under a nearby large rock, find the Silver and Wood Tankard.

Hidden Chamber: Head up the stairs and examine the vines to the right to discover a hidden chamber.

Deccani Bronze Spouted Bowl: Proceed to the tower and rappel down its side to the beach with the chevron. Sam should meet you with the boat. Your destination is a cave on the side of the large island, near the ledge where you found the Persian Leather Notebook Case. Inside the cave, park the boat next to a pillar, climb it, and swing across to the opposite wall. Follow the path to the riverbed and turn right to find the Deccani Bronze Spouted Bowl on the tunnel floor.

Mughal Elephant Carving: Exit the cave and head to the front of the temple. Use the ledges to find a tunnel leading to a beam. Cross the gap, shimmy right, climb up, and cross the tree trunk. Boost Sam up the ladder. When he breaks the bridge, use it as a ladder to climb up. Turn left, jump across the gap, and check the dead end to the right for the Mughal Elephant Carving.

Optional Conversation: Climb the wooden supports to reach a platform. Jump to the beams sticking out of the wall, swing to the far wall, shimmy left, and drop down to meet Sam. Walk to the edge of the cliff and speak with Sam for an Optional Conversation.
