Le Loup Gris [The Gray Wolf]

You are submariners of the Kriegsmarine, aboard U-390, one of the most sophisticated submarines of the time, very close to Utah Beach. Your war engine has just been hit by depth charges. Before the latter sinks and takes you with him, you have one last mission: to recover a coded message, crucial in this battle of Normandy, thanks to an ENIGMA machine. Damaged U-390 won't let you reach the command room so easily. But who said it would be easy? Good luck.
