He will begin on the Roof, and the player must watch him on the camera to slow him down. Once he appears in the office, he is seen climbing on the desk. The player must shut off a camera, hide under the desk (50/50 chance of survival), or turn off the power to lure him away. He makes banging vent-like sounds when he moves.
