Operation X is a special stage available in Ace Combat X: Skies of Deception. It is unlocked by completing all of the game's missions, which requires at least three playthroughs. A non-canonical mission similar in concept to "The Gauntlet" from Ace Combat Zero: The Belkan War, Operation X has players engage the game's fictional aircraft, such as the XFA-24A Apalis and the YR-302 Fregata.

Objectives

The goal in Operation X is to fight through formations of all of Ace Combat X's original aircraft, excluding Fenrir. As you progress through the mission, enemies will begin spawning all around your position, often overwhelming you in higher difficulties. Once the X-02 wave is destroyed, you will be engaged by a squadron of four ADF-01 FALKENs, each armed with TLS laser pods. Destroying the FALKEN formation will finish the mission.

In Normal mode and higher, once a single ADF-01 remains, two unidentified aircraft will spawn on opposite sides of the map and engage the player. The aircraft in question are the aces ADF-01 "Z.O.E." and XFA-27 "Scarface" from Ace Combat 2, bearing their original paintjobs. Killing both pilots will unlock their respective aircraft's Special paint scheme.

Trivia

• Operation X marks the first occasion where an enemy-controlled ADF-01 is able to use the TLS. Unlike the player, however, the TLS-wielding FALKENs will often hit with quick swipes that deal low to medium damage, instead of outright killing the player.
• All the enemy aircraft are the ones that can be tuned in the Hanger for the player.

Enemy units marked as TGT usually must be destroyed to advance the mission. The TGT text is always in red, except if the player changes this in Ace Combat 7.
