Sorry for any confusion this may have caused!
The Golden Toolbox and the Hatch are connected
Since we know the hatch was created by someone and not the Entity, I think the hatch was created using the golden toolboxes. A survivor from the past who might be long gone, maybe Alex or maybe Vigo, created the hatch using the golden toolbox, maybe thats why they are on almost every map out of reach left there by the survivor who used it to build the hatch and escape. It had to have been before Benedict since he documented escaped through the hatch before, so he wasn't the one who made it. Thoughts?
