Into the Unknown is the last Investigation and final act of Hell is Us. Once started, there is no turning back until you reach the ending. Unlike the other acts, this part of the game has no exploration points to uncover but mainly focuses on the conclusion of the story.

You can only continue exploring the world of Hadea once you finish the credits. After being reloaded into the main menu your complete save file will have a mark and will load you in on the last save you made before the final cut scene.
