Resident Evil 7: Biohazard · Unlockable item
The Secrets of Defense
The Secrets of Defense is an unlockable named item; the guide says it becomes available after completing the game on Normal or Madhouse difficulty.
How it works
The supplied unlock guide gives the completion condition as Normal or Madhouse difficulty. It does not describe the item’s effect, how it is used, or whether it applies across subsequent runs. The gameplay passage separately says some bonus items can be added to item boxes for subsequent runs, but does not specifically connect this item to that behavior.
