In Ground of Aces, you build and micromanage a World War II air base that is inhabited by a diverse cast of pilots and crew members. While you can play Ground of Aces in a never-ending free build mode, the Theatre Campaigns will give you specific glimpses into World War II and the challenges air bases and their crews had to face, such as the story of the Battle of Britain. It is inspired by free form base builder games like Rimworld and Going Medieval and history strategy games like Hearts of Iron IV. The art style will pay homage to the “ligne claire” style of Franco-Belgian comics like Biggles and Buck Danny.
