Operation Sea Lion

Operation Sea Lion 1940 is a turn-based WWII strategy wargame set across southern Britain, the English Channel, and northern France. Command German landing forces as you attempt the historically doomed invasion of the United Kingdom, balancing flexible landing locations with the immense logistical challenge of keeping troops supplied against growing British naval supremacy.

Choose between a concentrated invasion or multiple landings, manage supplies and reinforcements, and outmaneuver a capable AI opponent using encirclements and tactical attacks. Game variation, adjustable difficulty, customizable maps and unit icons, animation controls, and optional British reinforcements provide a highly replayable experience. Inspired by classic tabletop wargames, the game recreates the alternate-history question of what might have happened if Germany had launched Operation Sea Lion in 1940.
