I found a secret, locked trapdoor in front of the soda machine inside the supply closet directly next to the bookstore. How do I activate it? I had to use the sonic screwdriver, as the soda machine did not bear any buttons to open it. Plus, when I actually went down the hole, i just teleported directly to spawn!

you need to know a password for the trapdoor, also down the hole is something like MSA room or something
