Choose from one of our missions below!
It's July 1942 and the outcome of the war is balanced on a knife edge. We need you to cover 30 miles on foot, travelling across Cairo in it's blistering heat. Your mission is to track down an enemy agent and identify who has been leaking British Intelligence before the Nazis figure out Enigma has cracked their coded messages and change their codes. Can you handle the heat?
It's 1941 and the United Kingdom is in terrible danger. Your mission is to help us secure a new line of communication from Bletchley Park to the Cabinet War Rooms in London. We need you to walk the 50-mile route, making contact with key agents to solve puzzles along the way. Can you figure out the code and deliver the message to Winston Churchill before it’s too late?
It's 1942 and the situation in France is at boiling point. The Nazi occupation has cut us off from our agents on the ground, so we need you to go behind enemy lines to make contact. We cannot afford for our intel to be compromised, so you must move through the shadows and crack codes along the way to avoid detection. This mission is not for the faint hearted. Do you have what it takes?
