Appearance: silver locker that looks like a locker to store stuff in but with 2 wheels and the inside has buzzsaws and can brutally kill you alive inside, glows orange when the locker doors open and has a very small triangle on the top.

The Locker has a really simple mechanic.
Scanning or shining a flashlight at it will make it charge at you after a small windup, assuming you are in its line of sight. However the locker doesn’t speak and doesn’t have a voicebox.
