Iron Coffins: North Sea Expansion

Iron Coffins: North Sea Expansion is a tactical-level, narrative-style solitaire wargame using a tables-based game engine simulating the German Kriegsmarine U-boat war against Allied shipping in the North Sea during World War II.

As the captain of a Type II 'duck' U-boat during 1939-1940, your ultimate goal is to locate and sink as many enemy Allied ships as possible, while at the same time bringing your U-boat and crew safely back to base after each patrol. It won’t be easy due to persistent enemy aircraft and escorts continuously hunting your U-boat, but the German people are depending on you. Don’t let the Fatherland down!
