Resident Evil 7: Biohazard · Equipment unlock
X-Ray Glasses
X-Ray Glasses are a bonus item unlocked by completing the game in under four hours on any difficulty; they provide a permanent psychostimulant effect.
How it works
The unlock guide states that completing the game in under four hours on any difficulty unlocks X-Ray Glasses. The gameplay passage describes bonus items placed in item boxes on subsequent runs and gives glasses with a permanent psychostimulant effect as an example. The sources do not explain the effect’s precise operation or how it compares with ordinary psychostimulants.
