Wolfsrudeltaktik

Wolfsrudeltaktik is a card game where players take the role of World War II German U-boat wolfpack commanders. The objective of the game is to prevent the Allies from shipping enough supplies to Britain to end the war early, and to sink more enemy tonnage over the course of the war than your opponent.

Manage your submarines, utilize your special skills, and choose carefully which convoys to attack; the Allied destroyer escorts are always on the lookout to sink a German U-boat.
