The Aperture is a giant creature and sub-boss in the survival-horror game The Evil Within 2. It appears as a large mass of writhing tentacles surrounding an eye designed after a camera lens. This entity is a psychological construct of Stefano Valentini, who had lost an eye during his time as a wartime journalist. The eye represents the concept of Stefano opening his eyes to new ideas and overseeing everything taking place within Union and STEM as a whole.
