Sorry for the double post but I have found something with amazing potential. SCP-1609 Finally a way to go to and explore all those SCP's that won't be implemented due to the stupid "it's in a certain location" junk

You find the chair in the facility and when you interact with it the chair could teleport you to the other locations ( the transition could be applied through short loading screens) to places such as a fenced in SCP-087 and more!
Also, SCP-707 another easy one to impletment. once it's in your inventory if you click to use it the SCP puts a smaller copy of itself in your inventory (up to 3-4 until it kills you)
layer 1 you just get a message saying your hair and nails fall off
layer 2 you take more damage than usual and if gas hits you it will due minor damage to you
layer 3 kills player?
