I am stuck at a door that requires a thumbprint in Episode 1. What do I do?

Return to the area marked “Investigation” on your map. The room has a looping shape.

Jump to the cameras in the back find the Prizrak named Shell. In OMNI View, look for an orange square behind him. Interact with it to get the thumbprint. The square will then turn gray.

Return to the door that requires the thumbprint. Enter OMNI View and interact with the thumbprint icon to unlock the door.
