Bendy and the Ink Machine

In the chapter where you have to power up the Haunted House to rescue Boris, you will open a door and it will be leading to a room where the Projectionist is prowling (creepy guy with a projector for a head)

Go down into this room and push the switch on the right, this will bring the lift up and the Projectionist will be alerted that your there and will chase you, run back up where you came from and hide in the hiding spot at top of the stairs

When he is out of site, go back down and try and make your way up the stairs in that room (it was the left side for me) when at top you should see a cardboard cutout with a hole for the face and a camera pointed at it, look through the hole and at the camera, you should hear a click from the camera and the achievement should pop, move around a little or push X if it don't work straight away
