• Strut L: In the far corner of the small room behind the windows.
• Shell 2 Core, 1F Air Purification Room: In the vents, using the Nikita.
• Shell 2 Core, B1 Filtration Chamber No. 1: Underneath the wreckage, underwater.
• Shell 2 Core, Locker Room (Where Emma Emmerich is hiding): It's hiding inside the locker (This locker can only be opened in Extreme mode. However, there's a Claymore mine that is set inside the locker, which will kill the player instantly if it's not destroyed or picked up).
• Strut E: In the room with the Digital Camera, behind the northernmost boxes.
