03 - ...Everything Is Permitted | Sequence 11 AC IV: Black Flag Guide

Follow Ah Tabai

After you start, follow Ah Tabai. He will give you another toy to play with - a rope dart. Using this one, you can hang the enemies up on trees, drag them to yourself, to be able to kill them at close quarters, etc. The attack will begin so, run towards the coast.

The hanging of a soldier

OPTIONAL OBJECTIVE- use the rope guards to hang two guards

OPTIONAL OBJECTIVE- use the rope dart to pull three guards

You will reach the first group of soldiers. Climb onto a tree to hang two of them. To do that, shoot at the target, using the shoot button, then lean the left analog stick towards yourself. Your character will jump down from the branch and leave the hanged soldiers there. Once you have already hanged two soldiers, there are still three more to pull. You do that in the very same way, but while on the ground. It should not be problematic for you to complete the optional objective, if you have used up all of the ropes before you do, remember that you can craft new ones (1 bone for one dart). After you have completed the optional objective, it will probably be more convenient for you to use pistols, smoke bombs, etc. Still, the rope is also very useful,, especially against brutes and officers. To all intents and purposes, the entire mission is about fighting. Additionally, you will receive reinforcements in the form of the other assassins so, it should not be too difficult. Keep cutting through the successive groups of enemies, until you reach the coast.

Run towards the ship

On the coast, you will have to kill twenty soldiers and a captain. The best thing to do is to run straight for the ship (and kill, along your way, whoever you can), because there is a plethora of soldiers and killing 20 is not going to be a problem at all.

The rope pulling the captain

When it comes to the captain himself, the rope will come in handy. You do not even have to pull him, it is enough if he trips - then you will be able to strike while he is on the ground and kill him in one blow. Once you have killed everyone, the mission will conclude.
