Sequence 2-6: The Treasure Fleet

Optional Missions:

- Free 23 pirates

- Kill 3 guards from behind corners

Follow the onscreen prompts to free yourself from the shackles. Once free, stand by the door and whistle to get the guard's attention. Grab the guard and kill him when he gets near. Go to the next cabin and check the left area. Whistle again then perform a stealth kill on the guard that you lured. Continue to the last room and and kill the the last guard stealthily to complete the optional mission. Recover your gear then climb the nearby ladder to reach the ship's deck.

Once outside this ship, engage all enemies and free the 9 prisoners here. You only need to free 18 pirates for the main mission but you have to release 23 to complete the other optional mission. (And get the 100% mission synch) Once done, swim towards the next ship to the east. Like before, do not use stealth on the ship; go under the deck and clear the guards so you can release all prisoners inside.

This next one is the final Man O' War ship for this mission. Board it and take out all enemies on the deck. Once done, enter the hatch door in the middle of the ship and climb down. Take out the remaining guards inside and free the last batch of pirates. Go back to the deck and to the large brig in the sea beside the man o' war. Take out the brig's captain then eliminate his remaining crew.

Capping the Cap

After commandeering the brig, you'll have to control it and escape. Sail to the objective point and keep your speed to go out of the enemy ships' firing range. Faster gunships will pursue you but you don't have to engage them; just sink them if ever they're getting in your way. When the rogue wave is about to hit your ship, face it head on or brace yourself. You should also do the latter in case your ship is along the path of a watersprout.
