The Rust Gas, the Key, and the Sunken Treasure
After surfacing, follow the passage around until you see a worker robot near some switches. Disable the guard with a water arrow, then flip the switches. Doing so will open the doors to the sub-aquatic storage areas. There's a guard blocking the doors. Sneak up and knock him out or just use a gas arrow. Go into sub-aquatic storage area 2.

Shoot the guard near the door with a gas arrow. Take the flash bombs from the shelf. Go down the hall. Break the glass to get some potions, then continue through the passage until you come to the pirate shanty. Go upstairs and knock out the guard. Grab the four cargo bay keys. Go downstairs, open the door, and jump in the water.

Swim straight under the walkway until it turns. Then, surface and climb up. Knock out the guard and continue down the walkway. Knock out the guard by the door and take the main cargo storage key. Unlock the door and search the chests - one will have the rust gas canister.

Return to the central area and enter sub-aquatic storage area 1. Go through the doorway on the left. Enter the watcher control room, knock out the guard, and flip the switch. Return to the entrance. Go down the hallway to the locker room. Search all the lockers for some loot and items. There's a small hole in the floor. Jump in. The key to cargo bay 5 is in the water here. Follow the passage around. In the next room, look for a purse on the ground. Now, climb up the ladder and out of the water.

Go out of sub-aquatic storage area 1 and turn right. There's a nearby tunnel leading into the water. Go down and swim south. On the south wall is a tunnel blocked by rocks. Move the rocks and swim through the tunnel - have a breath potion ready, it's a long swim. When you surface, climb out, read the note, and enter the boat. Swim through the cargo hold to the chest. Open it, then swim out. Fight the ghost or just run by and jump in the water. Swim back to the main area under sub-aquatic storage area 1.

The New Scripture and a Fantastic Voyage
Swim over to the main pirate base. Search it for loot. Now, return to the main area of sub-aquatic storage area 1. Climb the stairs to the top. There are a number of guards here, so be careful. Eliminate the guard presence (gas arrows will help) and follow the walkway over to the tunnel in the wall. Jump in the water and swim into the right-hand passage. Surface for air. Leave the passage and continue down the main tunnel. You'll come to a floating book - read it, then swim out the tunnel.

Now, return to the submarine and enter through the underwater hatch. Search cargo lockers 1 through 4 for items if you wish. Unlock cargo locker 5 and get inside to end the mission.
