Namco Bandai is looking at Ace Combat: Assault Horizon somewhat like a reboot of the Ace Combat franchise. Impress Watch reports this the game is not a numbered title because the Ace Combat series will be reborn as a new series with Ace Combat: Assault Horizon.
Following in the footsteps of Ace Combat: Joint Assault, Ace Combat: Assault Horizon takes place in the real world. The story begins in Africa.
The theme of the game is "an agonizing death by blazing wings." Namco Bandai promises plenty of destruction and high-speed dogfights, like the one shown in these screenshots.
