They works more like trap. It shares same visuals as Bloodshot Eye, although it constantly shoots Technology 2 alike beam, and spins clockwise. Beam damages not only the character, but enemies as well. Room with Stone Eye features few blocks, which can be used as cover, since the beam does not go through. Once room is cleared, trap deactivates.
- After clearing the room, if the character goes into the other room and go back, the Stone Eye disappears.
