The Battle of the Atlantic lasted as long as World War Two itself. By the summer of 1942 one Allied ship was going down every four hours, yet German U-boat losses remained frustratingly low.

Play the game as a 'Senior Officer Escort'. In charge of the destroyers and corvettes tasked with defending the increasingly important convoys, you will need to learn about the tactics you can use to outwit German U-boats, and discover the strengths and weaknesses of both friend and foe.

Have you got what it takes to lead a convoy across the perilous North Atlantic?
