In reaching Tsushima's northern region, you're quickly closing in on the end of Ghost of Tsushima.

You'll need to gather your allies and more intelligence about the Mongols' plans across the last few missions of the game.

Below is the complete walkthrough for Act 3 (if you're looking for Act 1, it's right here; Act 2 is here). Check out the rest of our Ghost of Tsushima guides for rundowns on all of the Character Tales, Mythic Tales, and sidequests--as well as detailed guides for finding all of Tsushima's many collectibles and upgrades.
