Assassin's Creed 4: Black Flag Abstergo Cheats and Challenges
In Assassin's Creed 4: Black Flag there are several Abstergo Challenges that occasionally pop up whenever you complete different tasks. Most of these are relatively simple tasks that occur simply through playing like Perform 5 Double Assassinations, Reset Your Wanted Level at a Local Officer, Unlock 5 Taverns. Other tasks are a bit more complicated and are created more for the completionist, such as Solve All Mayan Stela Puzzles and Explore all underwater shipwrecks.
However, as you complete these challenges, Assassin's Creed will begin to unlock Abstergo Cheats. These can be found through the Start Menu, under Abstergo Challenges, and then Cheats. In this menu, you can also see your progress on all of the challenges. There are 100 challenges total.
These "Cheats" are fun ways to alter aspects of the game, but they will turn off the save on your game, and you can't progress further in the story with these Cheats enabled. Some of them also have effects in the multiplayer mode as well.
These are the Abstergo Cheats, and at what level you can unlock them:
- Number of Challenges Completed: 10
- Effect: You can now control the day and night cycle, and toggle it to be always day or always night.
- Number of Challenges Completed: 20

Now to get to unlock an Abstergo Cheat like the Deceased Crew, it takes a very long time. As mentioned in the AC4 Black Flag Collectibles Guide there are 200 Animus Fragments alone, and finding all of them is one of the Challenges you must complete to unlock the Cheat.
