The idea from Starboard would actually be quite interesting, because it really depends on movement skills. I would love this as an sub category! (Im quite late to respond but would still be pretty funny. Sadly the mods arent really active anymore)

If you are in the elevator and then look to the right, you will see a door that you can reach through the skip where you jump on the "umbrellas" (idk the name) and then jump on the elevated platform with people. If you know a freecam mod or something then just reply!
