The game's development was headed by Totally Games veteran Lawrence Holland and LucasArts director of development Randy Breen. Secret Weapons Over Normandy is a spiritual successor to this ten-year-old dogfighting series and contains a number of homages to Totally Games' previous works, including unlockable X-Wing and TIE fighter aircraft. Before working on the Star Wars series, however, Totally Games was also responsible for producing a trilogy of WWII flight simulator games: Battlehawks 1942, Their Finest Hour, and Secret Weapons of the Luftwaffe, also published by LucasArts. Rounding out the list of features is the ability to enlist a friend, for cooperative play or for competitive dueling, in a variety of multiplayer modes.Secret Weapons Over Normandy is a World War II aerial combat game developed for LucasArts by Totally Games, a studio best known for producing the acclaimed X-Wing and TIE Fighter games.

Voice acting is performed by Will Lyman, narrator of the PBS television series Frontline, and international film star Mako, who provides the game's Japanese Imperial dialect. To further draw players into the game, sound effects were re-created using actual field recordings of aircraft flown during the time period. Flyable aircraft includes the P-38 Lightning, the P-51 Mustang, the Me 163 Komet, the Me 262, and the B-17 Flying Fortress. The action takes place over a period of four years, where players will become active participants in such infamous battles as the Evacuation of Dunkirk, the Battle of Britain, Operation Sea Lion, Battle of Midway, and the D-Day invasion. Developer Totally Games draws from its experience in creating the popular Star Wars: X-Wing series for this project, offering a similar structure of cinematic storytelling, notable characters, and intense dogfights and bombing runs. Players will engage in 15 combat theaters, taking them from Europe and the Eastern Front to North Africa, China-Burma-India, and the Pacific. Inspired by LucasArts' original Secret Weapons of the Luftwaffe, released in 1991 for computers, players become members of an ace squadron that is given the most harrowing assignments in the war.

Secret Weapons Over Normandy features 20 authentic World War II aircraft in a series of 30 air-to-air and air-to-ground missions.
