- This article is about an in-game mission. For the in-universe event, see Operation Sighthound.
"Liberated" ("Unexpected Visitor" in Hong Kong and Taiwan) is the first DLC mission in Ace Combat 7: Skies Unknown. Details on the mission are scarce; the mission will be released in autumn 2019 for purchase. Players can either purchase the mission on its own for USD$4.99 or obtain it by purchasing the Season Pass.
The mission takes place on September 4, 2019, placing it after "Bunker Buster" and before "Cape Rainy Assault", thus making the mission take place during the OADF's gradual push towards capturing Farbanti.
