Mark of the Ninja scrolls and challenges guide – The Trail of Shadow
This challenge is a classic one. We’ve got a case of the levers today, three different doors with levers which raise and lower different doors. If you run around flipping random levels it may take a while, but that’s why you’re here! The solution is simple. First, turn off both lasers (unless you feel like dodging them constantly).
Deactivate the top left lever.
Leave the top right lever up.
Lastly, operate the bottom right lever, then go get your scroll!
