03 - Tainted Blood | Sequence 12 AC IV: Black Flag Guide
Last update: 11 May 2016
Havana has been shut out for all civilians so, to start this mission, you will have to sneak your way inside. Before you start, make sure that you have, at least, 10 pistol bullets. It is also a good idea to expand the number of pistols that you carry, as much a s possible, and have on you a gun with the greatest punch.
Once you start, start jumping towards the cathedral. Around the cathedral, watch out for a gunner. Do not walk into the cathedral's premises and go along it, by jumping over rooftops.
Once you reach the end, you will notice your target on the rooftop. They will start going in the direction from which you came so, start backtracking and move back a bit, if necessary, to avoid being spotted.
Stay close while going above. The way is quite long but, as for now, uneventful. Once you start approaching the fort, there will appear gunners on rooftops. To the extent possible, try to eliminate them silently by attacking them from behind or using sleep darts.
Assassinate Loreano Torres
OPTIONAL OBJECTIVE- stay out of combat
Soon, you will reach another familiar location. Using the trees show in the screenshot, reach the fort, just like you once did it during the second sequence.
Before you jump over onto the fort check carefully where the local gunner is. Jump up when he walks to the right, just like in the screenshot, and knock him down quickly by surprise.
Both on the right and on the left, there are soldiers patrolling the area, one at each side. You need to be especially careful when it comes to them. When the one on the right walks away, run quickly to the left and tackle down the guard here.
If you are short of ammo, deal also with the guards above and loot their bodies. If you, on the other hand, are ready, make sure that you are shielded from detection on both sides and wait for Torres to walk nearby. Once he is within reach, jump down and air assassinate him. This will initiate a cutscene.
Assassinate El Tiburon
OPTIONAL OBJECTIVE- use two guards as human shield
You will have to fight a mighty knight, and four guards, here Keep at a distance from Tiburon and wait for him to aim his pistol at you. Then, use one of the guards to shield yourself from the bullet. Repeat then for the second time to complete the optional objective. If you are attacked by the regular soldiers, counter their attacks to avoid taking damage but, do not press the attack button because you can easily kill all of them before you manage to complete the optional objective. If necessary, run away towards the yard's other end.
Once you have completed the optional objective and killed all of the guards, El Tiburon will remain in the battlefield. The traditional hand-to-hand fight is pointless here, he is also immune to darts. Keep firing your pistol at him. Use up the whole series and reload while running around the yard, in circles, to avoid being attacked. Once you are ready, use up the ammo again and start playing cat and mice again, while reloading. How many shots you are going to need, depends on the model that you are using but, in general, 7-10 shots should do. Once you kill him, a cutscene will start.
Escape and hide
After the cutscene, large numbers of soldiers will dash in through the gate. To the right of the entrance, note the glowing rope shown in the above screenshot. Use it to climb up. From there, jump towards the sea and dive to hide. Wait until things go calm again. Finally, you will have to return to the area where you have started.
