Panzerschreck Magazine #4.
From the rules:
Battle of the Atlantic is a solitaire game based on this important World War II naval campaign. It covers the decisive part of the campaign, August 1942 to May 1943. The player, assuming the role of Admiral Karl Dönitz, controls the German Kriegsmarine and tries to achieve victory against the Allies, controlled by the game system."
This issue also contains a smaller game, Berchtesgaden: The Alpine Redoubt covering a hypothetical WWII campaign against a putative "last stand" defense at Berchtesgaden.
As with all Panzerschreck games, the games require some assembly prior to play.
Scheduled for april 2015 reprint by One Small Step Games.
