INVESTIGATOR Trophy in Albedo: Eyes From Outer Space
Elementary, my dear Watson!
How to unlock INVESTIGATOR
Area: The Stairs
Warning: The box can became "stuck" in the surrounding items. If this happens, then reload a save to fix. For this reason you may want to force a save before trying (credit to Terminator).
Right next to the cabinet is a "heavy box". Keep picking it up, dropping it, and running into it until it flips over and you can observe a packaging label on its side. Once John says "a futile detail" while observing the box, then the Trophy will unlock.
