Ace Combat Xi: Skies of Incursion (エースコンバットXi, Ēsu Conbatto Irebun) is a 2009 combat flight simulator video game developed and published by Namco Bandai for iOS, which released on 3 December 2009.
Skies of Incursion takes place during the same time period as Ace Combat X: Skies of Deception, however Skies of Deception tells its story through the point of view of Gryphus Squadron while Skies of Incursion tells the story from the point of view of the Falco Squadron, a separate unit in the Aurelian Air Force.
Aurelia, located on the southern edge of the Osean Continent, has lived in peace for many years due to its mild climate and vast underground resources. Unfortunately, in the year 2020, the country was invaded by the neighboring country, Leasath, under the command of Diego Gaspar Navarro. The invasion was under the guise of Aurelia supposedly promoting civil war in Leasath. Aurelia was caught vulnerable and was quickly defeated within a matter of 10 days, this was due to the overwhelming power of Leasath's advanced superweapon - the Gleipnir Flying Fortress. The true motive behind the invasion was only later revealed to be Diego Gaspar Navarro's personal profits in arms deals during the war.
The remnants of Aurelia's military, being reduced to a single operating airbase, quickly banded together to launch a last-ditch counter-attack against the invading Leasath forces to liberate their homeland.
