Ace Combat: Assault Horizon (Japanese: エースコンバット アサルト・ホライゾン Ēsu Konbatto Asaruto Horaizon) was the 14th game released in the Ace Combat series. It took place in the world, albeit in a different timeline from that of Joint Assault. Players took control of various members of Task Force 108, most notably William Bishop, as they attempted to shut down the threat posed by Andrei Markov and other rebels from Russia.
