I was at Exit last night, my group also tried the lab. We got stuck at the same spot (direction and SCP-418 lock). I'm disappointed that they don't give you the option to get the solution at the end, it would've been nice b/c frankly, even if I go back to Exit, I think I would try one of their other rooms. Before that I would likely try some of the other facilities.
Did anyone find the coin for a bonus prize?
If any of you know the answers to these, please pm me:
