"Geez, how many planes they got lined up at the border? We've only got four on our side...we'd better abort."
Jack Bartlett

Open War is the second level of Ace Combat 5: The Unsung War.



The mission's primary targets are eight reconnaissance UAVs. As the player shoots them down, a squadron of four fighters will appear, but cannot be targeted.

Mission Update

As Chopper fails to outrun the fighters and Heartbreak One engages them, they become the mission's primary targets. Shooting them down causes another squadron of three fighters to appear. Shooting them down ends the mission.
