The Warrior’s Code is one of the main quests you need to do in Ghost of Tsushima.
Your task is to help Yuna search for her brother Taka who is a blacksmith.
Here’s a walkthrough of The Warrior’s Code in Ghost of Tsushima.
Head to the marked area on the map and you’ll find Yuna fighting. Speak to her to begin.
Reach an overlook
Next, you’ll be required to go to an overlook by the Mongol Prison Camp as marked on the map.
Use the guiding wind to help you and Yuna will follow you there.
Survey the camp
Go to the marked area on the screen and survey the Mongol prison camp.
Enter through the gap
Head towards the Mongol prison after surveying the area. Go through the front. There’ll be a gap you can pass through.
Assassinate the Mongol
This is the part where Jin learns to bend the honor code. You can assassinate the Mongol if you sneak up behind him.
Follow the bear tracks
After killing the Mongol, Jin will have a flashback. Playing as younger Jin, follow the bear tracks on the ground.
Keep going until you reach the bear carcass. Examine it.
After the flashback, continue infiltrating the prison camp.
You can stealth kill all the way through. You would also have learned the skill to see the location of all enemies.
There’ll also be supplies around the area to loot, together with a Mongol Artifact inside the bigger tent.
You’ll then find a cage. Open it and free the prisoner inside.
Follow Yuna and the Straw Hat
After freeing the Straw Hat prisoner, follow them both towards the river.
The quest ends here and you’ll get further intel on Taka.
