# Ace Combat 7: Skies Unknown

Ace Combat 7: Skies Unknown is a 2019 combat flight simulation game by Bandai Namco Entertainment. The first new entry in the Ace Combat series since 2014's Ace Combat Infinity, the game was released for PlayStation 4 and Xbox One in January 2019, and for Windows in February 2019. A Nintendo Switch port was released in July 2024.
Ace Combat 7's plot marks the series' return to its traditional setting of Strangereal, and follows the exploits of "Trigger", a fighter pilot who is assigned to a penal squadron following an accusation of murder, in the midst of a war between the countries of Osea and Erusea. The game features support for virtual reality, offering a set of missions developed for the PlayStation VR headset, as well as several downloadable content packs offering new missions and content. It is the first game in the Ace Combat franchise to be built on Unreal Engine 4.
Ace Combat 7 received generally positive reviews from critics and became the highest-selling entry in the series, with over six million units sold across all platforms by January 2025.

## Gameplay

Like the rest of the Ace Combat series, Ace Combat 7: Skies Unknown forgoes a realistic flight model in favor of faster, arcade-like gameplay to increase its accessibility to newer players. The player can also choose Novice or Expert control settings; the latter enables the player to execute realistic aircraft maneuvers such as rolls, high-G turns, and Cobra maneuvers. The game features 28 different aircraft, with an additional nine as downloadable content and the F-4E Phantom II offered as a pre-order bonus. As with previous entries in the series, most of the aircraft are licensed from real-world manufacturers, although a set of fictional superplanes are also included. Several aircraft in the game make their series debut, such as various members of the Su-30 family, as well as upgraded versions of older aircraft like the Gripen E and A-10C Thunderbolt II.
Players earn an in-game currency, "Military Result Points," via gameplay to purchase additional aircraft and equipment through a tech tree. The player begins the game with the F-16C, and is able to unlock the MiG-21 and F-104C Starfighter after the fourth single-player mission without using MRP, with the F-22A Raptor, Su-57, and the fictional X-02S Strike Wyvern as top-tier aircraft in the tech tree. Each aircraft is equipped with standard missiles for both air-to-air and air-to-ground warfare, as well as another special weapon. Special weapons, including anti-ship missiles and laser weapons, are used to boost an aircraft's ability to carry out air-to-air or air-to-ground attacks. Equipment purchased may also be used to boost the performance of the aircraft beyond its base performance, such as higher-spec engine or airframe parts to enhance its speed and survivability respectively. Only eight upgrades may be applied at any time, weight limitations limit the number of a specific type of upgrade that can be applied (e.g. limit to number of simultaneous applicable airframe parts), and certain upgrades are only usable in the multiplayer mode, while others are only available in the game's singleplayer mode.
For the first time in the series, clouds interfere with aircraft, hindering the player's vision and targeting systems when passing through them and rendering laser weapons ineffective due to refraction. In addition, aircraft briefly ice up and stall after staying in clouds for too long, and lightning strikes temporarily disrupt controls and sensors. Each aircraft also carries a limited supply of flares that can be deployed to evade missiles in critical situations.
During the single-player campaign, players complete a series of combat missions that tell the in-game story. Players are given an in-game briefing prior to a combat mission, where they are informed of success parameters, expected opposition, terrain features, and weather conditions using a 3D map display. Players complete missions by destroying various air and surface targets, as well as accomplishing specific mission targets (e.g. destroying in-flight IRBMs). AI-controlled wingmen accompany the player through the mission, providing exposition and potentially shooting down enemy planes for the player. Over the course of the single-player campaign, the player may choose to engage in additional minigames, such as in-flight refueling or landing. These minigames can be skipped, but reward small amounts of MRP for completion.

### Multiplayer

The player may choose to play in the multiplayer mode regardless of any progress made in the single-player campaign. The multi-player mode comprises the Team Deathmatch and Battle Royale modes. Both modes are PvP, where players shoot down enemy aircraft to earn points against a timer. The two modes differ in that Team Deathmatch involves two teams of four players each, whereas Battle Royale is a free-for-all mode. Shooting down top-scoring players and players using higher-tier aircraft confers more points than shooting down worse-performing or lower-tier players. If a player's aircraft is destroyed, they respawn after a few seconds. When the time limit is reached, the team or player with the greatest score is declared the winner.

## Synopsis
### Setting

Ace Combat 7 is set in the series' fictional universe of Strangereal, where Earth has entirely different nations, geography, and history. The game's story details the 2019 Lighthouse War, fought between the Osean Federation and the Kingdom of Erusea in the continent of Usea. Following the Continental War, Osea brokered a peace treaty between the Federal Republic of Erusea and the rest of the Usean continent, while the International Union (IUN) formed the IUN Peacekeeping Force (IUN-PKF) to maintain peace there. In 2011, Erusea was restored to its historical status as a monarchy ruled by the D'Elise royal family, while former Osean president Vincent Harling ordered the construction of the International Space Elevator (ISEV), a space elevator and communications tower used to convert atmospheric energy into energy, off the coast of western Usea near Erusea. The ISEV is protected by two massive Osean airborne aircraft carrier drones known as Arsenal Birds named Liberty and Justice, carrying a large number of combat drones, advanced weaponry, and force fields, and receiving their power via microwave transmission from the ISEV. Though Harling intended for the ISEV to be a symbol of lasting peace, Erusea viewed it as a symbol of Osean imperialism that infringed on Erusean sovereignty, with these resentments ultimately sparking the Lighthouse War.
Players control the game's silent protagonist, Osean fighter pilot "Trigger". The game's frame story is told through pre-rendered cutscenes played between missions, primarily from the point of view of three characters: Avril Mead, an Osean civilian aircraft mechanic who broke wartime aviation laws and is forced to work in an Osean penal military unit; Rosa Cossette D'Elise, the princess and heir of the Erusean throne who believes the war will end Osean interference on the continent; and Dr. Schroeder, a Belkan scientist developing advanced combat drone technology for the Erusean military.

### Plot

Rising tensions between Osea and Erusea culminate when Erusea launches a surprise attack on Osea and captures much of the Usean continent, including the ISEV and both Arsenal Birds, with former Osean president Vincent Harling still in the ISEV. Consequently, war breaks out between Erusea and Osea, the latter supported by the IUN-PKF. Avril, who was flying a refurbished F-104C Starfighter when the war began, is shot down by an Osean fighter jet pursuing an Erusean drone, arrested for breaching wartime aviation laws, and transferred as a mechanic to the Osean 444th Air Base, a military prison disguised as an air base where Spare Squadron is based.
Trigger, part of an Osean IUN-PKF squadron based in eastern Usea, fights to repel Erusean forces, but the IUN-PKF suffers heavy losses to the Arsenal Bird Liberty and Erusean ace Mihaly A. Shilage, who provides flight data to Dr. Schroeder's drone program. Trigger leads a mission to extract Harling from the ISEV, but an Osean air-to-air missile strikes Harling's rescue aircraft, killing him. Trigger is accused of firing the missile, found guilty by court-martial, and transferred to Spare Squadron. Considered expendable, Spare Squadron is sent on highly dangerous missions with minimal support to probe Erusea's drone defense network for weak points, frequently losing members in the process. Trigger encounters Mihaly again and dogfights him to a standstill, impressing Mihaly before both are forced to retreat due to inclement weather. For their commendable performance, all members of Spare Squadron are pardoned and transferred to a base on Tyler Island, off the southwestern coast of Usea, while Trigger and his wingman Count are recruited by the elite Long Range Strategic Strike Group (LRSSG). Osea and the IUN-PKF launch a counteroffensive against Erusea, destroying Liberty using the sole operational "Stonehenge" railgun and liberating most of Usea. Meanwhile, Princess Rosa Cossette D'Elise, who initially promoted anti-Osean sentiment, becomes disillusioned with the war.
Osea launches an assault on the Erusean capital of Farbanti and manages to capture the city. Trigger encounters Mihaly again over Farbanti, but their duel is interrupted when Osea and Erusea use anti-satellite weapons against each other, causing a collisional cascade that breaks down satellite communication networks worldwide and disables both sides' IFF signals. As Mihaly escapes in the confusion, Erusea loses control over its AI-controlled drone fleet and collapses into a civil war between conservative and radical factions seeking to end and prolong the war respectively. At the same time, multiple Erusean states declare independence, including Mihaly's native Shilage, of which he is the ruler. With the network down, Dr. Schroeder travels to the ISEV to transmit Mihaly's flight data into a new generation of Erusean combat drones manufactured in automated factories, while the LRSSG, now cut off from command and forced to operate independently, attempts to regroup and find a way to end the war. The LRSSG attempts to extract an Erusean conservative informant, who reveals Harling was killed by an Erusean drone that spoofed Osean IFF signals, but he is accidentally killed by Osean forces who misidentify his extraction aircraft due to IFF failures.
Meanwhile, Avril and the 444th try to survive on an isolated Tyler Island in the midst of a three-way battle between Osea, Erusea, and rogue Osean penal units, and rescue Cossette from her shot-down liaison aircraft. Assisted by the LRSSG, Avril and Cossette lead an evacuation of the island and travel to the ISEV to seek aid; en route, Cossette realizes Harling had peaceful intentions with the ISEV and that the Erusean radicals lied to her to spark the war. The LRSSG is forced to raid Shilage to replenish their supplies, but Mihaly arrives to stop them. Trigger duels and defeats Mihaly, who apologizes for his involvement and asks Trigger to end the drone threat before his aircraft crashes, leaving him unable to fly for the rest of his life. At the ISEV, Schroeder and Avril's group confront each other, and one of Mihaly's granddaughters destroys Mihaly's flight data before it can be uploaded to the drone network. Schroeder reveals he sought revenge for the loss of his country by forcing the nations that defeated them into needless conflicts, using his drone program and Mihaly's combat data to create a force capable of crushing Osea. Disillusioned by the destruction his program had caused, Schroeder agrees to help stop the factories, but reveals that the data was already uploaded to two advanced drone fighters, "Hugin" and "Munin".
A joint Osean–Erusean coalition assaults the ISEV to seize it from Erusean radicals, while Cossette and Avril disable its microwave power transmissions, allowing Trigger to destroy the remaining Arsenal Bird Justice. However, Hugin and Munin arrive and repel the coalition, intending to complete the data transmission and prolong the war. The next morning, Trigger leads a counterattack on the ISEV and shoots down one of the drones, but the other, having learned off Trigger’s fighting style, flees through a tunnel to the ISEV's bottom levels. Trigger and Count pursue the drone and destroy it and the signal repeaters to prevent the transmission, ending the war. In the aftermath, peace returns to Usea, and Cossette, now the leader of Erusea's newly-formed provisional government, leads the post-war peace movement in Harling's memory.

#### SP Missions

In the DLC missions, set between an attack on Erusean missile bases and the battle of Farbanti, the LRSSG is assigned to capture the Alicorn, an Erusean submarine aircraft carrier armed with a railgun, and Captain Matias Torres, a mentally-unstable ultranationalist who commands the Alicorn's cult-like crew and specifically despises Trigger. After failing to capture them at an Erusean port, and defeating a pair of mercenary pilots who attempt to assassinate Trigger, the LRSSG learns the Alicorn has defected from the Erusean Navy and that Torres plans to attack the Osean capital of Oured with a nuclear artillery shell, intending to kill one million civilians to force an end to the Lighthouse War. Using sonobuoys and a magnetic anomaly detector to locate the Alicorn, the LRSSG and Osean anti-submarine planes force it to surface and engage it in a protracted battle, eventually destroying the Alicorn and killing Torres.

#### VR Mode

VR Mode's plot follows Ace Combat 04: Shattered Skies protagonist Mobius 1 as he joins the IUN-PKF to battle the Free Erusea terrorist group in 2014, five years prior to the events of the main game. This storyline occurs separately from the main plot.

## Development

Despite lackluster reviews, Ace Combat Infinity for the PlayStation 3 was a surprise hit for veteran fans, and commercial interest in the series by Bandai Namco was renewed, prompting internal development team Project Aces to develop a true sequel, the first mainline Ace Combat game since 2007's Ace Combat 6: Fires of Liberation for the Xbox 360.
Due to the original Ace Combat engine being in a state of limbo since the release of Infinity, Bandai Namco decided that rather than incur the costs of building a new Ace Combat engine from the ground up, Skies Unknown would be the first game in the franchise to be built on Epic Games' Unreal Engine 4. "trueSky", an Unreal Engine plugin that generates realistic clouds, played a notable role in the game's development, being one of the first additions to the game.
Ace Combat 7's development process used "sandaibanashi", a rakugo storytelling technique using three subjects; for Ace Combat 7, the subjects Project Aces used were "space elevator", "princess", and "three-dimensional cloud". A teaser trailer shown at PlayStation Experience 2015, a very early impression of the game created before development properly began, prominently featured all three subjects. Ace Combat series producer Kazutoki Kono told the development team the elements of the teaser had to appear in the game, and declined a suggestion that the teaser simply be a "product impression". The game was developed by Project Aces and Bandai Namco Studios Singapore, which used a "Western style" of development and organization compared to Project Aces' "Japanese style", resulting in a cultural gap that both teams had to overcome. Development was assisted by the Japan Air Self-Defense Force and the Japan Maritime Self-Defense Force, who offered technical advisors and aircraft information.
A significant amount of work went into the game's virtual reality mode, exclusive to PlayStation VR. Initially, the entire campaign was intended to be VR-compatible, and all of the game's cutscenes were created with VR compatibility to the point of audio post-production; however, they were canceled because of framerate issues with the PlayStation 4 and the difficulties in making VR missions, which were created separately from campaign missions. Ultimately, only three VR missions were added to the game, following a storyline separate to the main campaign; three more missions were planned but were not released. Much work also went into the game's sound effects and music, with the game's soundtrack by series composer Keiki Kobayashi.
Two-player local multiplayer was rumored to have been included, but was not added; in the final game, only online multiplayer exists. Development of the online multiplayer mode was designed to provide the same experience regardless of platform, location, or skill level, and playtesting was conducted overseas.

## Release

Ace Combat 7 was officially announced by Bandai Namco during PlayStation Experience in December 2015. Originally set to be released in 2017, the game's release was eventually delayed to 2018, before finally being released for the PlayStation 4 and Xbox One on January 18, 2019, and for Windows on February 1. Preorders for the game came with digital copies of Ace Combat 5: The Unsung War for the PlayStation 4, and Ace Combat 6: Fires of Liberation on the Xbox One. The game was also released on the Nintendo Switch on July 11, 2024, making this game the first installment of the series to be available on a Nintendo home console, not counting the series' spiritual spin-off The Sky Crawlers: Innocent Aces, released on the Wii.
Ace Combat 7 features post-release downloadable content that adds new aircraft, missions, roundels, squadron markings, and paint schemes. The earliest of these DLCs will be included for free in the Switch version. On May 26, 2022, DLC adding content from Top Gun: Maverick, (which was released the following day) was released.

Ace Combat 7 received "generally favorable" reviews from critics, according to review aggregator website Metacritic.
Famitsu magazine gave Ace Combat 7 a rating of 35/40, the highest of those reviewed in issue 1571. Eurogamer's John Linneman recommended the game as a return to form of the Ace Combat series, and praised its gameplay, graphics, music, plot, and VR mode, deeming it an "absolute must-play". Forbes contributor Ollie Barder gave the game a 9/10, saying "while it can be a demanding game at times, it is definitely a rewarding one", though he lamented the limited scope of the VR compatibility and opined that the inclusion of only three VR missions did not justify buying PlayStation VR.
Eurogamer.it's Antonio Savino, Game Informer's Andrew Reiner, GameSpot's Edmond Tran, and GameRevolution's Jason Faulkner each gave Ace Combat 7 a rating of 8/10. Savino highlighted the game's graphics, sound, and music, though he noted that due to a lack of a "fairly convincing blur effect", things often felt "still", even at high speeds. Reiner highlighted its gameplay, sound, and presentation, but criticized the uneventful multiplayer experience and the campaign's "preposterous" plot, calling it "a Fast and the Furious story that is trying to be touching and serious, but it just doesn’t mesh". Tran praised the game as marking the series' return to form as well as its gameplay and VR experience, but noted the campaign had "tedious" missions with sparse checkpoints. Faulkner said the game had a "great story" with excellent graphics and a replayable multiplayer mode, though he lamented the absence of features from previous titles such as wingman commands or branching campaign missions, criticized the game's design as being "a bit too safe", and noted the VR mode lacked motion sickness safeguards, making it difficult to play through, though he added that it was worth it.
IGN's Mike Epstein rated the game 7/10, approving of the graphics and overall gameplay experience, but criticizing its odd mission pacing, "convoluted" story with lengthy and unavoidable exposition, "poor communication of objectives", and "confusing controls", with his overall verdict stating that "It's enough to prove that there’s room for the [Ace Combat] series to make a comeback, though this game will be not the one to jumpstart it."
Kazutoki Kono, responding to Epstein's IGN review on Twitter, criticized him for using Normal controls, which are basic and designed for newcomers, instead of Expert controls, which are more realistic and offer more control. Barder agreed with Kono and suggested that using Normal controls "just makes the game harder"; similarly, Faulkner noted that newcomers picking Normal "could accidentally play through the whole game [...] with controls that prevent them from getting the most out of the game".

### Sales

In Japan, Ace Combat 7 sold 202,379 units for the PlayStation 4 during its first week, and sold 286,570 units by March 2019. In Southeast Asia, the game sold over 500,000 units within a month.
