Ace Combat is a hybrid flight simulation action video game series featuring 18 games published by the Japanese company Namco Bandai Games and produced by Project Aces, an internal development team. The series emphasizes fast-paced action and dramatic plots, and has established itself as one of the most successful arcade flight action franchises.
Most games of the series take place in the same fictionalized world populated with fictional countries with details loosely based on real-life location, events, and wars. One of the main selling points of the series is the ability to pilot a range of aircraft that include accurate or slightly modified representations of present-day military aircraft, prototypes that never saw actual battle, and completely fictional boss-type superweapons. Longtime fans of the series are rewarded with small hints of the continuity between the games, as some characters and events are referenced from one game to another.
