Description[]
"Close the fortress gates".
Guide[]
Once you meet up with your brother and get to the area called "The Fortress Gates" you are faced with quite a tough puzzle. You can give it a few tries on your own but if you give up here is the sequence of lever moves to use. When I give a direction I mean which direction to push/pull the actual lever, not the resulting moving of the pieces.
Middle: Counter-Clockwise, Right: Clockwise, Left (the one by itself): Clockwise x2, Middle: Clockwise,
Right: Clockwise, Left: Counter-Clockwise x2, Right: Clockwise x2, Middle: Counter-Clockwise x2,
Left: Counter-Clockwise x2, Middle: Counter-Clockwise, Left: Clockwise
You will now trigger a cutscene in which you see your brother again. Just progress through a bit more platforming and the trophy will unlock.
