We did the Bunker with a group of five. The room was not properly set up before the game. We have found the exit key in two minutes, because it was just staying there unlocked!! Still, not ruin our whole experience, we carried on and solved the remaining puzzles that were supposed to lead us to the exit key. There is a major flaw in the context of the game that can lead you to the final key anyways without solving any of the rest of the puzzles. I would have given this place a 1 star, but the owner was very kind to us, so I am giving a 2.
