Optional Objectives:
- Kill eight guards by destroying powder kegs
- Use a Rope Dart to kill Roberts
Sail to the exclamation point to enter Principe and start this memory. Swim ashore by the Animus Fragment on the left, which you can get, and then enter the stalking zone on the left. There are 2 powder kegs on the slope to your left that will cause a chain reaction when hit, so target them with free aim and when the large patrol walks by and stops hit it. Use Berserk Darts on the remaining guards and finish off anyone left.
Head behind the house, between it and the ramp to the upper level, and follow this to a large area of stalking zones with a Brute. Take out the Brute and then spot the powder keg in the street and wait for another patrol to finish off your optional objective. You can then distract the searching guards with a few Berserk Darts and backtrack to the ramp.
Though there is no need for stealth the less enemies you have on your tail the better when you find Roberts. For this reason, I suggest you kill all the guards in your way before approaching the coast and spotting Roberts. Once spotted, Roberts will jump onto his ship and leave you to fight his minions. You don't want to kill them all, as a clock is ticking down, so throw a Smoke Bomb down and kill two and then head for the tree and jump into the water. You will need to reach the Jackdaw's helm in the alloted time or fail.
You can't follow Roberts directly at first, so sail around the cover and dwindle his life with Mortar and Chain Shot while avoiding the Fire Barrels. Even if you manage to get the ship almost sunk the life will not deplete until you get to open water so save your ammunition. Once the British ships arrive, finish of the Royal Fortune.
Use the lift to get to the top of the Jackdaw's mast and make your way to the main mast above Roberts and target him with the Rope Dart and hang his ass.
