Reaching a one-eyed prisoner | 7: Overturn DMC: Devil May Cry Guide
Last update: 11 May 2016
After regaining control, you can just follow one path. Don't worry that you can't use any skill - the game will display soon a cut scene.
Place yourself where the screen above shows and use Angel Lift. After landing on the roof of wagon, fly to the next car using Angel Boost. Next two steps are using Angel Lift on Boost Ring and Angel Boost to get onto a shelf where prisoner fights with monsters.
The first encounter with Harpies in front of you. Avoid their distance attacks, which shouldn't be too frequent (screen above).
Harpies can defend well against using of Demon Pull, but you can easily reach them with Angel Lift. But do not use it too often, because you may get into abyss. It's better to wait until Harpy flies over a platform. Defeating all of them ends mission.
