02 - Royal Misfortune | Sequence 12 AC IV: Black Flag Guide
Last update: 11 May 2016
Right after you start, jump into water and swim towards the left side of the shore.
OPTIONAL OBJECTIVE- kill eight guards by destroying powder barrels
After you go out of water, you will find gunpowder barrels around. Along the path above, there is quite a numerous group of pirates. Wait at a safe distance, hidden behind a tree or rocks, until they start to walk down. Once they are low enough, discharge your pistol at them. Most probably, they are out of reach but, this is not the point. The noise of the gunshot should attract their attention, as well as of all the remaining pirates nearby. Note that as many as seven reacted to the gunshot in the screenshot.
Immediately aim at the barrels with the other pistol. Wait for two seconds, so that as many pirates as possible approach them and take a shot. The explosion should claim the majority of them. Much depends on your luck but, if you have coordinated everything well, the explosion will kill 4-6 of them. The noise will attract the attention of the other guards in the region. Kill them in a more traditional way. If you decide that there is too many of them, retreat towards water as they come down and hide. Then wait for some of them to return and kill the remaining ones. After the action, loot the bodies and go up, towards the camp.
Under the big palm, a bit past the entrance to the camp, there are more barrels. There also is a group of three, patrolling. Deal with them and you should complete the optional objective. If you still need any barrels, there are quite a few of them in the camp. Some of them directly in front of the camp's gate so, you can encourage someone to chase after you, escape towards the barrels and blow them up afterwards.
After you complete the optional objective, the best idea is to ignore the rest of the pirates and focus on Roberts. You can find him in a specially fenced "mini-fort" from which you once saved pirates for him. Once you run inside, he will jump down onto his ship. Jump after him immediately. Under the cliff there will appear the Jackdaw.
Soon after the pursuit starts, Roberts will get into your way so, sail right, around him, while minding the rocks.
You will get under mortar fire. Cower from the shots, take cover and respond in kind.
Once you get back behind him, watch out for the barrels that he throws and blow them up immediately. In the meantime, you should conduct mortar fire an chainshot fire. After some time, you will sail out into the open waters where both you and Roberts will be attacked by the English. Ignore their ships and focus all your attention on Roberts's ship. As soon as you are ready, board the ship.
Assassinate Bartholomew Roberts
OPTIONAL OBJECTIVE- use the rope darts to kill Roberts
Once the fight ensues, use the crane to make it over to the mast quickly. Deal with the gunner there and jump onto the sails to slide down.
Once you are as low as you can get, but still above the ground, wait until Roberts gets within range. Then, shoot at him and remember to pull the left analog stick towards yourself. Roberts will hang down from the mast. This will start a cutscene after which the mission will conclude.
