Ace Combat X2 – Joint Assault is a combat flight simulation game for the PlayStation Portable, serving as a sequel to Ace Combat X: Skies of Deception. The game features improved aerial combat mechanics, introducing an Enhanced Combat View that modifies the appearance of enemy aircraft. This creates a more immersive experience and prepares players for intense dogfights.
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.
