Part 1: Tailing
After starting the mission, we’ll need to trail the pair of guards nearby. As per usual, hit Eagle Vision to tag them. Follow them from a distance along the first length of the dirt path and hire the dancers here for 150 Reales so that we have a moving hiding spot. Wait for the soldiers to move past the guards blocking the road. When they do, use the dancers to distract the guards and continue through.
Make your way up the road until you see the Gunner on the roof of the building on the left of the street. Climb the roof and take him down quickly. Use the path through the trees here to reach the next rooftop. Hop onto the next set of branches to your right and follow it to the end and perform a leap of faith into the haystack below. Use the stalking bushes to continue after the targets.
As they start moving down the hill to go to the beach area, follow the cliff to the right of the road whilst keeping an eye on them. Use the stalking bushes scattered around near the ledge here, avoiding or killing any guards that get in the way. Once you reach the end of the cliff, perform a leap of faith down to the haystack below.
Hop out and enter the stalking zone bushes to the right of the tents in the encampment here and continue after the targets up the small hill until they stop. This will end the tailing sequence.
Part 2: Assassinate
Once the main objective has been updated, the good news is that we are now able to be detected without risk of failing the mission. There is an optional objective at this point that asks us to assassinate three enemies from stalking zone bushes.
There are plenty of enemies available in this area, so sneak up and kill the obvious enemy by himself near the stalking zones and then lure some other guards over to hiding places to take them down as well. Once you have killed three of them in this fashion, you will fulfil the requirements for the optional objective.
Now that we have sorted out first optional objective it is time to proceed with the primary goal – assassinating the Templar target. It is worth noting that the second optional task for this mission requires that we assassinate him using an air assassination attack.
To do this, use the trees, rocks and other debris in the water to make your way out to the ship in the bay. The target will patrol in a square pattern from the back of the boat, up to the centre, across and back to the rear end of the vessel again. I started by climbing up and clearing out the front of the ship of the two enemies here quietly. Next climb the rigging on one of the sides of the mast here.
Once up on the higher platforms, work your way over to the front of the ship (you can get rid of the gunner in the centre if you like, he can be a little troublesome). After you arrive at the front of the ship, drop down to the lowest boom on the mast.
From here; wait for the target to pass below you, target him and perform your air assassination to complete the optional task and the sequence.
