Ace Combat Joint Assault is a flight combat game developed for the PlayStation Portable. Building on its predecessor's gameplay, it introduces significant enhancements, including the Enhanced Combat View, which changes how players perceive enemy aircraft by resizing them for a more immersive experience. This feature serves as a precursor to the Dogfight Mode seen in Ace Combat Assault Horizon.
Joint Assault retains the basic gameplay from its predecessor, but with significant additions and alterations. Aerial combat adopts a visual system called `Enhanced Combat View` to alter the perspective of enemy aircraft close to the player, altering their size to make them appear much closer as a precursor to Dogfight Mode from Ace Combat: Assault Horizon.
