Based on the Lion part of the board game. France has fallen. England stands alone against the might of a triumphant Germany, defended only by the Spitfire and Hurricane squadrons of the Royal Air Force. Hitler orders his mighty Luftwaffe to destroy the RAF in preparation for Operation Sealion—the invasion of England. German fighters and bombers fill the English skies and the RAF responds. Scenarios range from one raid day, taking an hour to complete, to the full campaign, playable in 12 hours.
