Grubengold [Mine Gold]

There used to be many stories and legends about the mysterious passages in the mountain. One suspected stolen gold or even the amber room, but then everything turned out to be just an air raid shelter. The training mine was later built there. You are a group of lost placers and treasure hunters and you have found a map in an old archive that shows a room that is not on the training mine's official maps. Apparently, the room is almost a hundred years old and has not been opened before. During a tour of the training mine, you successfully broke away to open the secret room. But you didn't think about the traps from times long past and now you have to get out in time...
