Assassin's Creed III Remastered Walkthrough

12. ACIII: The Underground

The Underground Network

The Underground Network is new to Assassin's Creed 3. You'll be introduced to it in Sequence 5, Memory 3 (Boston's Most Wanted). You need to explore the Underground in both Boston and New York. Doing this will give you more Fast Travel locations. To use a Fast Travel location, when you find them, you'll either need to unlock a door (either by picking the lock, or by turning a mechanism, or by solving a Magic Lantern.

There are a couple of obstacles in the Underground that can make it a bit harder to explore, but none of them are difficult to get around. You'll have a lantern that will be used to light your way in the Underground, without it you'll be traveling in darkness. There are lights on the walls throughout the Underground that you can light.

There are also a few enemies scattered through the Underground. Fighting them will involve you needing to put your lantern down - you can't do much while holding it, including running.

The maps below show the locations for all of the fast travels points in the Underground, along with the solution to the Magic Lanterns.
