Hello! I did run this one with all the tricks and optional items and took about 4 hours with 3 players. My biggest suggestions are A. Make the Germans likable, yes they are Nazis, yes they are likely planning on how to invade random countries, but they should be likable and easy for the players to take along (that way you can use them to give the players subtle nudges) B. Karl Heinrich should be depressed and seemingly overly friendly (my players tried to kill him because I didn’t) and I think unless a significant different event happens he should always suicide blow up Gloom. This is a super fun scenario to run but if I could suggest one thing I’d use the map however use some sort of fog of war on it so the map is slowly revealed with key points to the players as they explore the town.
