Ace Combat: Assault Horizon Legacy is a remake of Ace Combat 2. It is a flight-sim/arcade fighter combat action game. The game is typically played in a third person, behind the aircraft, or first person, inside the cockpit view. It features series mainstays such as numerous selectable aircraft and the ability to purchase parts and weapons to customize the fighters. Where Assault Horizon Legacy sets itself apart from current console versions of Assault Horizon in that the gameplay is tipped more in favour of the arcade-style action of the early games in the series rather than focusing on flight-sim characteristics. Also different from the console versions of Assault Horizon is that this entry takes place in the fictional universe of the older games in the series, rather than in real-world locations.
