Most of the Ace Combat games feature a hangar. This allows players to spend credits earned on missions to purchase aircraft, special weapons, and special paint schemes for player aircraft (only in Ace Combat 04: Shattered Skies and Ace Combat 6: Fires of Liberation).
In Ace Combat Infinity and Ace Combat 7: Skies Unknown, players can create an Aircraft Set to save a preferred combination of an aircraft, special weapon, tuning parts, aircraft skin, emblem, and nickname.
With Aircraft Sets, players are given freedom to prepare their favorite sets for both single-player and multiplayer. When sortieing in either type of mission, players may select one of their Aircraft Sets that would suit the upcoming mission.
