The thirteenth game in the ''VideoGame/AceCombat'' series--despite the name, ''Assault Horizon Legacy'' (known in Japan as ''3D Cross Rumble'') is a return to the world of Strangereal and an updated remake of ''VideoGame/AceCombat2'' for the Nintendo3DS, putting the player back in the flight suit of the leader of the Special Tactical Fighter Squadron "Scarface," who now has his own callsign--Phoenix.

The plot for ''Assault Horizon Legacy'' expands upon that of ''Ace Combat 2'' to more neatly fit into the Strangereal timeline. Here, the reason for the Usean Rebellion is rooted in the aftermath of the [[VideoGame/AceCombatZeroTheBelkanWar Belkan War]]; the nations of the Usean continent--who have a long history of political and military conflicts amongst themselves--[[EnemyMine banded together to form the USEA Allied Forces]] in response to the threat posed by two growing superpowers, the Osean Federation and the Union of Yuktobania Republics.

However, a group of southern Usean nations preferred an alliance with Osea. The [[VideoGame/AceCombat04ShatteredSkies Federal Republic of Erusea]], Republic of North Point, and other nations in Northern and Western Usea protested this; they resented the idea of Osean military presence and feared that Osea would take USEA's natural resources for itself, but the southern nations negotiated a military pact with Osea anyway.

On the day that the USEA Allied Forces were to formally sign a treaty with Osea, conservative extremists organized a continent-wide coup d'etat, headquartered in North Point's capital of St. Ark. Many Allied Forces units joined the rebellion, warring on their former comrades. With fears that the rebellion would successfully take over the USEA government, the faltering Allied Forces launch Operation Fighter's Honor, assembling the 37th Air Force 18th Fighter Wing 9th Special Tactical Fighter Squadron, "Scarface." Leading the charge is Scarface One, TAC Name "Phoenix."

Compared to ''Ace Combat 2'', ''Assault Horizon Legacy'' brings a lot of features from later installments--notably the involving radio chatter from ''Ace Combat 04'' onward, unlockable custom parts for aircraft as in ''VideoGame/AceCombatXSkiesOfDeception'', and ace squadron battles in the style of ''VideoGame/AceCombatZeroTheBelkanWar''. Similar to the Close Range Assault system in ''VideoGame/AceCombatAssaultHorizon'' and Tactical Maneuver Command system in ''Anime/TheSkyCrawlers: Innocent Aces'', ''Assault Horizon Legacy'' has a Maneuvers system which allows players to get behind enemy aircraft (provided the [[ChargeMeter Maneuvers Meter]] is charged enough) or dodge missiles at the touch of a button.

[[AwesomeMusic/AceCombat Oh, and we can't forget the music.]]

''Assault Horizon Legacy'' was released first on November 15, 2011 in North America, followed by a European release on December 2. Japan got it last, on January 12, 2012. In February of 2015, an UpdatedRerelease called ''Assault Horizon Legacy+'' was released to take full advantage of the extra buttons and 2nd analogue stick of the ''New Nintendo 3DS XL''.

Be sure to check out the '''[[Characters/AceCombatAssaultHorizonLegacy character sheet]]''' as well.
!!''Ace Combat: Assault Horizon Legacy'' provides examples of:
* AcePilot: Every-freaking-where. This ''is'' an ''Ace Combat'' game, after all. Most of ''Ace Combat 2'''s named aces make a return, as do the player's wingmen, Slash and Edge.
* AirstrikeImpossible: Remember the canyon run "One Night Stand" from ''Ace Combat 2''? It's back, and it's just as perilous.
* TheAlliance: The USEA Allied Forces.
* AttractMode: Used to cover the BackStory through an OpeningNarration {{Cutscene}}. [[http://www.youtube.com/watch?v=1vw208EiikY You can watch it here]].
* AwardBaitSong: The EndingTheme, "Gravity," ''sounds'' very much like one ... [[http://www.facebook.com/worldofnoel/posts/10150448185273276 although the lyrics]] [[SubvertedTrope are anything but]].
* [[AndYourRewardIsClothes And Your Reward is]] NoseArt: ''Ace Combat 2'' started the series' tradition of earnable custom paint jobs, and ''Assault Horizon Legacy'' does not disappoint. Each plane has five additional unlockable paint schemes, and two of those allow the player to choose custom colors.
* BottomlessMagazines: As per the series norm, any difficulty below Hard has infinite ammunition for aircraft cannons. On Hard and Ace, however, you'll only get eight hundred rounds or so.
* CallBack:
** Direct references to [[VideoGame/AceCombatZeroTheBelkanWar the Belkan War]] are made occasionally, such as the battles at the Round Table.
** In ''VideoGame/AirCombat'', ''VideoGame/AceCombat2'', and ''VideoGame/AceCombat3Electrosphere'', messages would appear in the middle of the screen depending on the context, such as "BULLS EYE!" or "BAGGED ONE!" when shooting down a target. ''Assault Horizon Legacy'' has brought these back, except now they're on the bottom of the screen and less distracting. Similar messages appear for successful Evasive Maneuvers.
* CallForward:
** Ulysses 1994XF04 is mentioned in a mission briefing as an "asteroid that was believed to be on a collision course with Earth." It's the reason [[spoiler:Fortress Intolerance]] was never demolished. One of the missions also has the player destroying a laser system originally made as a proposed Ulysses defense measure before the rebel forces can use it as a weapon, like what ended up happening to Stonehenge.
** In the debriefing for the mission "Fighter's Honor," Ulrich Olsen also mentions that the rebelling countries who had their armed forces demolished by the war will seek military expansion, and that Usea is now in a state of "armed peace."
-->'''Ulrich Olsen:''' [[VideoGame/AceCombat04ShatteredSkies Eventually, another time of war and strife will emerge, brought on by the still-burning coals left in USEA.]] When that time comes, we may need to call on your help again, Phoenix. You'll arise from the ashes of war again like a phoenix, and guide us to peace.
** During "Final Countdown," one of the sailors in the Rebel 1st Fleet may comment on Phoenix. "He's tough! [[VideoGame/AceCombat5TheUnsungWar Reminds me of the demon of the north!]]"
* CompositeCharacter: Some of the returning named aces from ''Ace Combat 2'' now share a single plane. For example, ''[=AC2=]'' had two Tornado F.3s piloted by Max and Goose. In ''AHL'' they fly a single YF-23A as "Max&Goose."
* CharacterCustomization: Like ''Ace Combat X'', custom parts can be unlocked and used on aircraft, including custom wing additions, armor, engines, and cockpit software.
* ChasingYourTail: Enforced; most missiles have a better chance of hitting the enemy when fired from behind, and the Maneuvers system allows Phoenix to automatically position himself behind a target.
* CivilWar: The Usean Rebellion, same as in ''Ace Combat 2''. Olsen mentions that some are calling this the Usean Continental War.
* ContinuityNod:
** Pixy's paint scheme is available for the F-15SE Silent Eagle, and the F-15 S/MTD has one that somewhat resembles Cipher's.
*** Schwarze Squadron's paint scheme is available for the [=MiG-31=] Foxhound. The F-16C likewise has an unlockable paint job similar to the ones used by Silber Squadron.
** The F-22 Raptor has an unlockable paint scheme that resembles Gryphus One's.
** One of the F-4E Phantom II's unlockable paint schemes is the one used by Mobius One during his first mission. One of the Su-37 Terminator's unlockable paint schemes is that of Yellow Squadron.
** The original Scarface One paint scheme is also available as an unlockable for the Su-37.
** Some of the unlockable cockpit software includes Garm's Eye and Mobius Loop.
* CoolBoat: The Dragonet-class subs make a return, and have been given names--the ''Fensalir'' and ''Folkvangr''.
* CoolPlane: The XFA-27 and ADF-01 FALKEN are back, as is the XB-10.
* CutscenePowerToTheMax: Both Phoenix and enemy pilots pull these off (for Phoenix, it's part of the Maneuvers system), using moves like the [[http://en.wikipedia.org/wiki/Kulbit Kulbit]], [[http://en.wikipedia.org/wiki/Pugachev%27s_Cobra Pugachev's Cobra]], and the [[http://en.wikipedia.org/wiki/Aileron_roll Aileron Roll]]--even if the aircraft is incapable of doing them in actual gameplay.
** The Maneuvers system is pretty much this trope in [[PressXToNotDie QTE]] form.
* DeathCryEcho: A lot of pilots and soldiers will do this after their vehicle is destroyed.
* DiskOneNuke: In ''AHL+'', the Princess Peach skin Typhoon can be unlocked in the mission to liberate Anchorhead early on in the game. While the Typhoon has about the same stats as the other starting planes, it has significantly higher speed than most planes until well into the midgame. Combined with Multi-Purpose Missiles and medium range anti air weapons, chasing down enemies becomes a lot easier.
* TheDreaded: After defeating the Cocoon Squadron, Olsen comments that the rebel forces are starting to see that you are a force to be reckoned with.
* EnemyChatter: And Friendly Chatter, too. A staple of the series.
* {{Foreshadowing}}: No big surprise to ''Ace Combat 2'' veterans, but Ulrich hints toward the confrontation with the ''Folkvangr'' after "One Night Stand."
-->'''Ulrich:''' Although I thought two Dragonet-class submarines were supposed to be built ... Well, let's leave it to the intelligence department.
* FrickinLaserBeams: The Tactical Laser System is back, available only for the FALKEN as a special weapon. [[spoiler: Z.O.E will only use it during Extra Mission 04.]]
* HighSpeedMissileDodge: Enemy pilots can do these to defeat missiles, in addition to or instead of dropping flares. Phoenix can do it via the Maneuvers system.
* HyperspaceArsenal: In the finest of ''Ace Combat'' traditions. All of the planes carry dozens of standard missiles, and quite a few special weapons on top of that.
* InterfaceScrew: Electronic warfare can do this periodically with your HUD, which also renders any of your homing missiles in flight useless. {{Justified|Trope}} as the HUD is a DiegeticInterface. There's an even nastier EW system that the [[spoiler: Z.O.E F-15 S/MTD and FALKEN]] use, creating false targets on your screen.
* KaizoTrap: Unlike the original game, you can still fail the mission by crashing after completing your objectives. ''Ace Combat 2 veterans, take note.''
* {{Leitmotif}}: ''Oh'' yeah--
** Like in ''Zero'', ''Unsung War'', and ''Assault Horizon'', the game has a general one that appears in a number of songs. Also like in ''Zero'' and ''Unsung War'', this leitmotif is the PlayerCharacter's theme song for the final battle, complete with a full orchestra choir.
** Each of the [[WolfpackBoss Ace Squadrons]] has their own unique theme song when you fight them; the Z.O.E. fighters have two different themes [[spoiler: and one more for the BrutalBonusLevel battle]].
* [[LethalJokeCharacter Lethal Joke Plane]]: Aircraft like the [=MiG=]-21-93 and ''especially'' the [[UsefulNotes/WorldWarII F6F-5 Hellcat and A6M5 Zero]]. The [=MiG-21=] has rather poor stats as a beginning aircraft, and the [=F6F-5=] and [=A6M5=] are prop-driven planes with no homing missiles, regular or special--but thanks to both the Maneuvers and customization system, these planes can shred even the mighty [[FinalBoss FALKEN]] to pieces. Even without Maneuvers or the customization system, the planes are still ''extremely'' agile, and the [=F6F-5=] and [=A6M5=] in particular have some of the most powerful [[MoreDakka machine guns]] of all the planes in-game.
* NewGamePlus: Phoenix keeps his rank, credits, unlocked planes, equipment, and paint schemes when starting a new campaign from the same save file after completing the previous one. This is also how Ace difficulty is unlocked.
* NoIAmBehindYou: Some enemy pilots, notably the ace squadrons and Z.O.E, will do this to get behind Phoenix if he's on their tail and fires a missile. Phoenix's defensive Maneuvers can also result in his aircraft dropping behind the enemy firing on him, usually accompanied by the message "'''[-NOW'S YOUR CHANCE!-]'''"
* NuclearWeaponsTaboo: Averted--the "Extra Powerful Cruise Missiles" of ''Ace Combat 2'' are referred to as advanced [[NukeEm SLBMs and ICBMs]] instead.
* PresentDayPast: From the real world perspective, there's a few aircraft from the TurnOfTheMillennium and TheNewTens that've shown up in this remake of a game made and set in [[TheNineties The Late Nineties]]. The PAK FA's first flight wasn't until January 29, 2010, and the F-15SE Silent Eagle didn't make its first flight until July that year. The F-35, on the other hand, didn't make its first flight until December 2006. The [=MiG=] 1.44 "Flatpack" first flew in February 29, 2000. All the other real world aircraft in the game were known back in 1997.\\
In-universe, this game marks the first time that the PAK FA and F-15SE Silent Eagle have been seen in Strangereal, chronologically as well as sequentially. This is also chronologically the earliest appearance of the [=MiG=] 1.44.
* RecycledSoundtrack: ''Assault Horizon Legacy'' does bring back a few tunes from ''Air Combat 22'', ''Ace Combat 2'', ''VideoGame/{{Ace Combat 3|Electrosphere}}'', ''VideoGame/{{Ace Combat Zero|TheBelkanWar}}'' and ''VideoGame/{{Ace Combat 6|FiresOfLiberation}}'', but these are in addition to the completely new thirty or so songs [[AwesomeMusic/AceCombat given the same loving care as other installments]].
** RearrangeTheSong: ''AHL'' brought back [[https://www.youtube.com/watch?v=LyKaaDF81EA the first stage theme]] from ''Air Combat 22'' for an extra mission, performed by an in-studio band[[note]]as an aside, this rearrangement was also used as the first stage theme for ''Mach Storm''[[/note]].
* TheRemnant: The Rebel Forces, representing the hardliners of the USEA Allied Forces that didn't want to join a military pact with Osea.
* TheRevolutionWillNotBeCivilized: The rebels are prepared to do some pretty heinous things in their opposition to the Allied Forces. For starters, after you take back Anchorhead, the rebels will later retaliate by sending bombers to the city with the intent on causing civilian casualties.
* SayMyName: If Phoenix is shot down, Olsen or Phoenix's wingmen will yell his name.
* ShoutOut: Quite a few, both in-series and out--
** Returning aces Tallman and Metal Sphere are references to ''Film/{{Phantasm}}''.
* SpellMyNameWithAnS: Several cases.
** The Round Table of ''Ace Combat Zero'' is called "Roundtable" here.
** Similarly, Cipher's unit in ''Ace Combat Zero'' was named Galm Team, although here the ShoutOut computer software "Garm's Eye" is spelled in accordance with the [[NorseMythology original reference]].
* ThisCannotBe: It's not uncommon to hear enemy pilots express shock or denial when Phoenix pulls an Attack Maneuver and is about to tear them a new one.
* UpdatedRerelease: ''Assault Horizon Legacy+'' takes full advantage of the 2nd analogue stick and extra buttons that come featured with the ''New 3DS XL'' system. The game also includes Nintendo-themed plane skins such as the F-22 Mario, the A-10 Bowser, the F/A-18E Donkey Kong, and the Peach Typhoon, among others. These skins provide different stats from their base plane, and can be unlocked through the Amiibo system or by shooting the easily visible yellow ?-blocks found in certain missions.
* VideoGameRemake: Of ''VideoGame/AceCombat2''.
* WolfpackBoss: Ace Squadron battles. Each squadron uses different strategies, and most of them stand a good chance of shooting you down mercilessly on Ace difficulty.
* WolverinePublicity: While the Japanese market title is ''Ace Combat 3D: Cross Rumble'', Creator/NamcoBandai branded the North American and European versions with a similar title to ''VideoGame/AceCombatAssaultHorizon'', even going so far as using ''Assault Horizon'''s cover art and logo style for ''Assault Horizon Legacy.'' Strangereal fans haven't been too happy about that.
