Key points of Map of Andreas Island - Assassination Contracts- Assassin's Creed IV: Black Flag
27. The Treasure Hunter
In spite of the numbering, this mission is the first one on the Andreas Island.
The target is staying on the Abaco Island, to the North of the Andreas Island. The target is, more or less, in the middle of the restricted area, occupied by a dozen, or so, scattered guards. Use the bushes to approach the target and either stab him in the back or discharge your pistols quickly. With a bit of luck, you will kill him faster than you are spotted.
25. A Slaver's Business
In spite of numbering, this mission is the second on the Andreas Island.
No reward for staying out of combat. The target is on the Andresa Island, close to the pigeon coop. Hide among the bushes next to the restricted area. After a while, there will arrive a British ship there (if you have arrived here by fast-traveling, you will notice that the moored Jackdaw tries to sail away. With a bit of luck, you will see both ships collide while trying to pass each other by). Onboard the ship, there is your target. The easiest method is to walk out onto the pier and shoot him but, if you feel like to, you can swim up to the ship and kill the target from above, by jumping down from the mast.
It may happen that, although you have killed the target, the contract will remain incomplete. In such a case, go aboard the Jackdaw and sink the enemy vessel. Then, the mission will be completed.
