This page is a guide on how to get the Secret Ending in Far Cry 6.
Reach The Guerrilla Mission
In order to unlock the secret ending, you’ll need to play through the story until you complete the mission Libertad Rises and have helped create the HQ on Zamok Archipelago. Here a cutscene will play out and you’ll receive a rusty boat which you can use to get around Yara easier.
After the scene has come to a close, avoid speaking with Juan Cortez and take the boat to sail to the edge of the map until you see “Leaving Yara, Turn Around!” on your screen which will cause the secret ending to playout.
What happens after the Ending?
Once you’ve seen the ending you’ll receive the Trophy/Achievement Hidden In Plain Sight and then you’ll want to reload your save and you’ll find yourself in Esperanza. Here you can choose to explore the end-game area or fast travel to any of the previous areas to continue the game as normal.
