Giant squid attack
Swim inside the Antocha shipwreck at coordinates 630,660. While looking out one of the windows you will be able to see a giant squid take down a whale. (Video)
- Complete the "Mister Walpole, I presume?" mission during Sequence 2 Memory 3. Pause game play while not in a mission, select "Progress Tracker", and choose "Sequence 2, Memory 3". Replay the mission and continue until you are given the optional objective to pickpocket three Templars. Pickpocket them to get at least 750 Reales. Immediately pause game play, select "Reload", and reload the game from the last checkpoint. You can now pickpocket the Templars again. Repeat the process until you collect at least 100,000 Reales.
- Note: This trick requires a decent amount of hull armor and 10 or more mortar rounds for the Jackdaw ship. Travel to the legendary ship battle in the northeast corner of the map, with the two legendary ships that attack you. You will not be able to defeat both ships without your ship fully upgraded, but you will be able to take down one if you follow these instructions. When the battle starts, fire two mortar rounds at the ship you are focusing on while turning around, then release your fire barrels. When they get close, use your heavy shot. Do not get between the two opposing ships or you will be defeated quickly. Once they pass, keep firing mortars at the one ship while they are turning around. Repeat the previous steps until you destroy the ship you are focused on. Pick up the loot from that destroyed legendary ship as quickly as possible, because the other ship will ram and sink you quickly. You will get 10,000 Reales for your trouble and be able to keep it after you die. Repeat the process as many times as desired.
- This trick requires the cannon and/or shot upgrades; or upgrades to your chain shot and ram abilities. Also, Brothers-in-Arms must not have been sunk yet. Start a battle with the group of ships, sinking one of them and ignoring the others. Collect your loot then intentionally fail. After respawning, the other ship will also be back with its loot. You will still have your previous reward. Repeat the process as many times as desired, earning 10,000 Reales each time.
When facing large ships (for example, frigates), position your ship near your target, then swim to the ship and eliminate the crew through close quarters. Afterwards, swim back to the Jackdaw then hit each ship with a single broadside. You will immediately win the boarding sequence that follows.
The IT Crowd reference
Go to the map near the entrance to the modern-day Abstergo offices. Two co-workers will begin talking about Chicago. Continue listening and they will talk about John from IT. The male co-worker comments that whenever he requests help, John replies with "Have you tried turning it off and on again?", which is a reference to the British comedy The IT Crowd.
Easy "Killer Killer" achievement or trophy
If desired, get harpoon upgrades, harpoon storage, strength, and extra armor to make this process easier. Sail to a Killer Whale hunting location (for example, coordinates 537, 340 on the world map). After a deck hand announces the presence of a whale, Kenway will be sent with a harpoon to hunt it. Harpoon the whale and follow it, being careful when it dives. It will eventually surface again on the horizon and run at your boat. Harpoon it again to avoid taking damage. Repeat the process until the whale's health is taken down to unlock the achievement or trophy. (Video)
Easy "Redingote Up!" achievement or trophy
Go to a General Store, then select the "Hunting Goods" tab. Purchase the Red Howler Monkey Skin for 5,000 R and White Jaguar Pelt for 6,000 R. Select the "Crafting" tab at the main menu, then choose the "Hunting Outfit" option. (Video)
