Escape From The Room: Enigma Express: Strangers On A Train

It's 1938 and the world is on the brink of war. Six strangers board a train, none of whom are what they first seem but they all have the same objective; a new super-weapon that is being transported across the continent. Each individual  is a spy, trying to capture the weapon for their own nation, but one spy has gone rogue which poses an even greater threat to the world. You and your team will take the roles of these spies, and through some puzzle solving, deductive reasoning and code breaking you will try and discover the identity of the rogue. For larger groups, one member can play the role of the rogue and try to sabotage your progress.
