Ace Combat Infinity

 is the latest entry in the Ace Combat series, officially announced on September 19, 2013 after a lengthy teaser campaign. Infinity is the third Ace Combat game explicitly shown to take place on Earth; it is the first free-to-play game in the series, as well as the first digital-only release.

Infinity follows a plot similar to that of Ace Combat 04: Shattered Skies. The game takes place in 2019, 20 years after the Ulysses Disaster. The player flies as Reaper, a pilot belonging to the Bone Arrow Squadron operating with the United Nations Forces to keep the world safe from a terrorist threat brought on by the events of the Ulysses Disaster. The game takes many elements from past Ace Combat games, from superweapons to aircraft to background music.

The game is exclusive to, will be free to download and play (restricted by the Sortie Fuel System), and will release in 2014. A public for Japanese PSN accounts was attempted in November of 2013, but shut down due to server issues. The game's story cutscenes were modified for unknown reasons and maintenance was performed on the servers. A second Japan-only beta began on December 12 and ended on December 19, followed by a worldwide beta that began on February 4 and ended on February 11, 2014.

Plot
In 1994, an asteroid named Polyphemus collided with the 1986VG1 Ulysses asteroid. The result was a mass of over 10,000 meteors that were expected to impact the Earth in five years. In response, the world's nations banded together to create the Stonehenge Turret Network, a network of eight anti-air railguns that would fire at the meteors to prevent as much damage to the planet as possible. Six of these facilities were built around the world to defend each corner of the globe. Unfortunately, in July of 1999, many of the asteroids crashed into the Earth regardless, causing a devastating loss of life in what was later known as the Ulysses Disaster. The world order began to fall apart, but a certain company named Wernher and Noah Enterprises assisted the world's nations in rebuilding efforts.

The game begins 20 years afterward. The refugee zones that were created post-Ulysses still exist - economically supported by Wernher. However, a multinational network of terrorists known as the Sons of Troia began to rise in power using the stockpiles of Wernher weaponry in each of the zones. They launched an attack on Tokyo using an modified version of a Wernher-made UAV known as the MQ-90 Quox. Due to the slashed military budgets as a result of Ulysses, the United Nations hired the Bone Arrow Squadron, a mercenary squadron owned and operated by Arrows Air Defense and Security, along with other mercenary squadrons. Bone Arrow was tasked with defending Tokyo during the attack.

Later, the terrorists launched another attack, this time on the Comona Base in the West Indies. This base was involved in developing the OLDS as part of a project called Shattered Skies. Bone Arrow Squadron was called on once more to defend the base from hostile transports and fighters. After they defended the base, the Greymen were kidnapped in Russia while the terrorists across all of the special zones began demonstrations around the weapon stockpiles.

At some point, the Stonehenge Type-3 network, located in Turkey, was likely occupied by the terrorists and used to attack the UNF. In response, the UNF launched a joint campaign between their Marine commandos, Bone Arrow Squadron, and Ridgeback Squadron, with the aim of destroying the Stonehenge Type-3.

Gameplay
The gameplay of Infinity is noted for staying true to the "classic gameplay" of the Ace Combat series, most notably Ace Combat 04: Shattered Skies. Close Range Assault, an integral component of gameplay in Ace Combat: Assault Horizon, is not included in Infinity.

Infinity-specific gameplay elements include the following:
 * All enemy units feature a health bar underneath their targeting box. This was a feature notable on Ace Combat 6: Fires of Liberation, but Infinity moves the health bar from the top-left of the HUD to directly underneath the enemy targeting box. Additionally, a white line on the bar indicates how much damage the currently-equipped weapon will perform on that target.
 * Tactical Datalink is a new feature that builds on the Friendly Assist System of Assault Horizon. When the player flies close to a friendly aircraft that they are linked to, their aircraft's performance is boosted. The exact boost is selected while editing a Aircraft Settings (see below). This also functions in single-player as well as multiplayer.
 * The head-up display shows the traditional radar and aircraft info (ammo, health, reloading) along the bottom of the screen; allotted score, remaining time, and the score of the targeted enemy are located on the top-left of the screen; and any checkpoints are noted in the top-right of the screen as they are encountered.
 * Oil and shrapnel will splatter on the screen when an enemy close to the player's aircraft is destroyed, similar to Assault Horizon.

During an interview at Eurogamer Expo 2013, Kazutoki Kono, lead producer on the game, said that the single-player campaign will work as a "tutorial" for what players might experience in the multiplayer mode.

Three superweapons have been confirmed to appear in Infinity. The first is the heavy command cruiser Aigaion, which appears in the multiplayer mission Moby Dick Pursuit. The second is an unnnamed Scinfaxi-class submarine, which appears during emergency mission updates in multiplayer. The third is the aforementioned Stonehenge railgun network, which is one of the main plot elements of the single-player campaign.

Multiplayer
Ace Combat Infinity features a multiplayer experience alongside the single-player story campaign, known as Online Co-Op Missions. The multiplayer experience is known as a 'competitive co-operative' experience where "skilled aces will form two teams and compete to inflict the most damage on a common enemy." Players can collect more in-game currency through the multiplayer missions than in single-player missions. Playing multiplayer also allows the player to earn experience towards further aircraft and parts through a technology tree, where further tech on the tree must be unlocked by purchasing all prerequisite technologies.

About halfway through each multiplayer mission, players will experience an emergency mission update that will interrupt their current objective and will direct the players to a new one. After this emergency objective is taken care of, the original mission will continue. The specifics of the update are random and range from engaging transport fleets to engaging a Scinfaxi-class submarine.

Customization
In a first for the series, Infinity allows players to customize and set up to four different Aircraft Settings, which include the aircraft, special weapons, aircraft parts, Tactical Datalink effect, and emblem that the player will be flying with during that sortie. Aircraft Settings can be selected in all gameplay modes, but Campaign mode provides free "Rental Sets" for each mission, intended for new players.

Similar to Ace Combat X, Joint Assault, and Assault Horizon Legacy, Infinity also has a tuning system which, after unlocking an aircraft, allows the player to upgrade that aircraft through the Aircraft Tree. Players can tweak their aircraft by swapping out and upgrading their aircraft's armor, missile power, gun damage, engine power, power of certain weapons, and more. Further aircraft and parts on the tree can only be unlocked if all of the aircraft and parts that show up previously on the same branch are unlocked and purchased.

The player can also customize the plane's color scheme from a limited set of colors, some of which can be purchased with real-life money while others with in-game currency. Enemy pilots and AWACS Sky-Eye will often make comments about a player's aircraft if it has a DLC skin on it.

Sortie Fuel
During Tokyo Game Show 2013, Kazutoki Kono confirmed that Infinity will have a restricted time system known as the Sortie Fuel System (similar to the token system in Tekken Revolution or the pricing model of Mobile Suit Gundam: Battle Operation).

When booting up Infinity for the very first time, players will start with 2 Supplied Fuel and 0 Stocked Fuel. Supplied Fuel replenishes at a rate of 1 unit every four hours at no cost, while Stocked Fuel is purchased for real-life money from the PlayStation Store. It is not possible to have more than 2 Supplied Fuel, but Stocked Fuel is unlimited. Players will have to choose one of the two fuel sources when playing a co-op mission or a single-player mission (the latter after completing Campaign mode one time).

Immediately after the announcement of this system, fans online expressed a distrust in the game and believed it would end up becoming a "pay-to-play" experience. The developers urged the players to keep their minds open and hold their judgments until the beta test began to provide constructive feedback. After compiling the feedback from the Japanese beta, Mr. Kono acknowledged that they are considering modifying the fuel system in some way. In fact, he would not talk about the specifics when asked, acknowleding that changes are on the way.

Contracts
While playing Ace Combat Infinity, three separate "contracts" can be enabled. Each one, when activated, will last for 12 hours and award the player bonuses ranging from extra credits for completing a mission to having a higher chance of receiving Moby Dick Pursuit. Contracts can only be purchased through the PlayStation Store for real-life money.

Aircraft
Teaser 00 introduced the CFA-44 Nosferatu (possibly NPC-only), PAK FA, Su-35 Flanker-E, and the F-3 Shinden II (possibly NPC-only) as the first aircraft confirmed for Infinity.

Teaser 01 added the MiG-21bis Fishbed, MiG-29A Fulcrum, F-14D Super Tomcat, and Typhoon to the list of confirmed aircraft. It also introduced the MQ-90 UAV  (likely NPC-only).

Teaser 02 added the F-16C Fighting Falcon, F-35B Lightning II, Su-32 Strike Flanker, F-22A Raptor, Su-33 Flanker-D, and B-2A Spirit (likely NPC-only) to the list of confirmed aircraft. The official screenshots of the game released simultaneously also confirmed the Su-25TM Frogfoot, MQ-90, and CH-47 Chinook (the latter two likely NPC-only). A promotional wallpaper later published showcased the F-2A Viper Zero, which was later seen in-game as a playable aircraft.

The Ulysses Disaster trailer added the F-4E Phantom II, F-15C Eagle, Mirage 2000-5, F-15E Strike Eagle, A-10A Thunderbolt II, C-17 Globemaster, and Il-76 Candid (the latter two NPC-only) to the list. During an interview at Eurogamer Expo 2013, Kazutoki Kono mentioned that they aimed for around 30 playable aircraft at the time of the game's release. 23 aircraft were playable during the beta.

References to past games
Infinity is likely the Ace Combat game to include the most references to other Ace Combat games. Some of the past Ace Combat elements underwent a process known as, where set pieces from the other games are embedded into Infinity. The list of retconned elements are as follows:
 * The Ulysses 1994XF04 Asteroid - The asteroid is now known as 1986VG1 Ulysses, and the impact event is known as the Ulysses Disaster.
 * AWACS SkyEye - AWACS Sky-Eye is the AWACS of the Ridgeback Squadron and during multiplayer.
 * The Stonehenge Turret Network - While the name is identical, Infinity brings a couple of changes to Stonehenge:
 * There are six facilities built on Earth rather than one.
 * The facilities and the cannons themselves are notably larger, at least double the size of the original Stonehenge.
 * There are three jammer towers in the center of each facility, rather than one small jamming facility.
 * The explosion effects are visually upgraded, and look similar to the explosions of burst missiles.
 * Stonehenge's attacks no longer "blanket" the sky above 2,000 feet. It seems to be safe to fly above 2,000 feet, but the unpredictability of where the shots will strike is still a problem at long range.
 * The Estovakian Aerial Fleet - The P-1112 Aigaion has been renamed to simply Aigaion in Infinity. The same treatment has been given to the P-1113 Kottos and P-1114 Gyges, which are now simply Kottos and Gyges, respectively. All of these airships are featured in the multiplayer mission Moby Dick Pursuit and during a mission in the campaign.
 * The Scinfaxi - A Scinfaxi-class submarine spawns at random during an emergency mission update in multiplayer.
 * Slash and Edge from Ace Combat 2 - A man named "Slash" is the flight lead of Ridgeback Squadron, and a woman named "Edge" is Ridgeback 2.
 * In the second trailer for the beta test, a red and black flag similar in design to the Osean Federation's flag is briefly visible.

Development
According to Kazutoki Kono, Ace Combat Infinity had been in development since early 2012, immediately following the release of Ace Combat: Assault Horizon Legacy and Ace Combat: Northern Wings. It was developed from the start to be a free-to-play game.

Teaser campaign
The game was first teased on June 14, 2013, when Kono tweeted a photo of his Japanese passport and his laptop, which displayed a revised version of the Project Aces logo with what appeared to be several objects approaching the ground from the sky. On June 21, 2013, the full-sized version of the logo was uploaded to the Project Aces Twitter account, and was set as the avatar and background image.

On July 10, a second image was uploaded to the Twitter account, containing part of a message, which read "ky fe||, the". Interestingly, the two L's in "fell" were formatted differently. This post was followed by another one a day later, consisting only of the word "closening" (meaning "to get close"), hinting that an announcement was imminent.

On July 11, a new website was set up by Namco Bandai, titled "PROJECT ACES NewTitle", which was subsequently announced through Twitter. The site contained the full teaser message, which read: "That day our sky fe||, the heavens split to create new skies." In addition to using the new Project Aces logo as its favicon, the code of the site contained the phrase "エースコンバット" (Ace Combat) as a keyword. It was later discovered that Namco Bandai filled a trademark for "Ace Combat Infinity" the same day.

Three times after the website's initial launch, the Project Aces logo background slowly faded into the page from the lower right corner. Finally, the second part of the sentence itself seemed to "split" into two parts, adding further symbolism to the message.

On July 15, however, the website completely changed, only showing a friendly radio transmission, indicated by the blue colored symbols around it: "<< Here comes the third strike! >>" Hours later, it was tweeted on the Project Aces Twitter account. On July 16, it was replaced with another friendly radio transmission reading: "<< All engines on Kottos 2 destroyed! >>" Once again, this message was tweeted a few hours later. On July 17, the image was once again replaced with a friendly radio transmission, this time reading: "<< Ridgeback One. Edge, report. >>" followed by the tweets a few hours later. Two hours after that, Kazutoki Kono wished everyone to "enjoy the official tomorrow."

Two hours before the Project Aces Twitter tweeted the Ridgeback One transmission, Kazutoki Kono stated that if the Project Aces Twitter reached 8,492 followers, he would release an image related to Ace Combat. When the number was met, he tweeted a picture of a soda bottle in front of a computer screen. The screen was displaying the Bone Arrow Squadron emblem.

On July 18 at 1:03 PM EDT, Tony Shoupinou (Community Manager at Namco Bandai Games, who had previously shared the "ky fe||, the" image as well) posted "Tomorrow @ 9AM (Central European Time), we will fly again. Yay! I can't wait." on his Facebook wall. At 9:00 PM EDT that same day, the image on the teaser site was replaced, this time not by a friendly radio transmission, but by the universal sign for infinity "∞", in the color red.

On July 19 at 1:03 AM EDT, 12 hours after Tony Shoupinou's Facebook post, Kazutoki Kono took to Twitter once more to inform everyone to keep an eye on their screens at 1600hrs Japan Time (the same time Tony Shoupinou mentioned, which would occur in 1 hour and 57 minutes), and to look at "it" without him since he would be at a meeting. Whatever "it" was referring to was not known.

On July 19 at 3:00 AM EDT, the NewTitle website was updated once again. This time, a teaser trailer (later renamed to Teaser 00) lasting 46 seconds for what was now confirmed to be a PlayStation 3 game, titled Ace Combat Infinity, was added to the site.

On July 26 at 3:00 AM EDT, precisely one week after the teaser trailer was uploaded, a screenshot of the briefing for Operation Fogbound was uploaded to the Twitter account, with the promise of more information to come next week.

On August 2 at 3:00 AM EDT, precisely another week later, Teaser 01 was uploaded to the site, providing a wealth of information. Simultaneously, Namco Bandai Games Europe uploaded the video with a confirmation that the game was a free-to-play game, along with some details on multiplayer as well as a quote from Olivier Comte, Senior Vice President. Later that day, Kazutoki Kono confirmed on Twitter, while replying to someone else, that Close Range Assault would not be a feature of Infinity.

On August 30 at 9:59 AM GMT, Kazutoki Kono tweeted a picture of what appears to be the main menu of Infinity. A couple of hours later, an article was posted on Gaming Age, a gaming news blog, with the third teaser trailer as well as some screenshots of the game. The third teaser trailer was then uploaded a couple of days later to the NewTitle website, titled "Teaser 02". The same day, Project Aces announced that Ace Combat Infinity was due to release in the Fall of 2013, with the release date itself to be announced at the Tokyo Game Show on September 19th.

Official announcement
On September 19 at approximately 2 PM Tokyo local time, Namco Bandai began the free-to-play segment of their Tokyo Game Show 2013 event, including Ace Combat Infinity. Here, while First Flight and a remix of Comona played, Kazutoki Kono discussed the details about Infinity after showing the "Ulysses Disaster" trailer. Later in the day, the video was uploaded to the official YouTube channel. For some reason, the release date announcement was postponed. Details later came in about the Sortie Fuel System. It was announced that a public would begin very soon.

On October 3, Project Aces uploaded official gameplay videos of the latter portions of the missions Great Migration and Stonehenge.

Beta testing phase
On October 17, Project Aces uploaded a video showing off more of the multiplayer, as well as members of the Project Aces team playing the game. It was announced simultaneously that the public beta testing would take place between November 7 and November 13, would require 2GB of free HDD space on the PlayStation 3, and would be Japan-only. Regions outside of Japan would partake in a second test, which was to follow the Japanese test but had no confirmed date at that time.

The Japanese beta contained the following:
 * Test Flight, a tutorial mission for new players where players can partake in tutorial exercises
 * Lost Butterfly and Great Migration, the first two missions of the story campaign
 * Completing these missions unlocked another teaser trailer, including more lines from the unknown female from the first teaser.
 * Tokyo Martial Law, Pipeline Destruction, and the Emergency Mission Moby Dick Pursuit, half of the multiplayer missions

The beta was entirely free, and the Sortie Fuel System, while active, was essentially irrelevant as the beta automatically granted players additional fuel. However, save data during the beta will not carry over to the game's full release. Players who participate in the beta will receive a special "2013 Beta Test Pilot" emblem, but this is as of yet confirmed only for the Japanese beta. Additionally, the requirements for obtaining the emblem are not clear as of yet.

Shut down
On November 8, one day after it began, the beta test was shut down to solve server issues that had been encountered. The largest problem was multiplayer missions terminating as soon as they started. The beta was expected to resume sometime near the beginning of the week of November 10, but by November 12 it was not up yet. Strangely enough, by November 12, fans began to notice that certain official Ace Combat Infinity media was being pulled from the internet. The Game Information Page was removed (and now redirects back to the main page), and the official trailers from Namco Bandai's international YouTube account were made private. No word was provided from Project Aces on either Twitter or Facebook concerning these changes.

On November 13, the date the beta was originally planned to end, Project Aces tweeted an apology for the elongated maintenance period, and assured fans that a second beta test would commence soon to make up for the first one having been closed so long.

New beta and changes
Soon after midnight EST on December 4, 2013, Project Aces reported through Twitter that a new beta will take place starting on December 12 and ending on December 18. However, they did not mention whether this would be restricted to Japan once more, or open to the world. On December 5, they released a new trailer showing off some of the single-player campaign as well as confirming the new beta date. The trailer also indicated that the beta would, in fact, be restricted to Japan again.

A second new trailer was released on December 9, giving more dialogue to both Slash and Edge, as well as some other unknown details including a butterfly squadron emblem, a strange visualization of what appears to be the Ulysses meteors, and a canyon flight. Fans later made a comparison between this second trailer and images from past trailers, and confirmed that changes were made to the story cutscenes. For example, the red portion of the Sons of Troia logo is a much lighter hue of red, and the map of Iyuli does not show any of the other cities or region lines around it.

The beta was re-released (under the same file) a few minutes before 11:30 AM Tokyo time on December 12, over half an hour before the usual update time for the PlayStation Store in that region. Simultaneously, a mandatory patch was released for everyone, regardless if they already had the beta installed on their PS3. Besides the minor changes to cutscenes as mentioned above (Sons of Troia edit, no regional/country lines (which also applies to briefings)), very little was modified from the November beta.

A few hours after the beta released, the New Title website completely changed to make it more of a "central hub" for news on the game, but the formatting of the website was incomplete with large spaces and misplaced text all over the site. Of note is that a survey section was opened, asking beta participants for their opinions on the game, which awarded anyone who completed the survey an exclusive desktop wallpaper.

The beta ran for a few hours longer than originally scheduled, and was closed on December 19. Later that same day, the release date was officially changed to 2014.

Worldwide beta
On January 8, 2014, Kazutoki Kono confirmed to a fan through Twitter that a beta was still scheduled for western markets before the game was to release. At the end of January, Namco Bandai announced that all of its subsidiaries would be known as Bandai Namco starting on April 1, 2014, to avoid confusion between Japan and overseas. It is unclear if Ace Combat Infinity is to be affected by this change. If the game releases after April 1, then the publisher will be known as Bandai Namco Games.

Simultaneously on PlayStation Blog and Facebook, Bandai Namco announced the dates for the worldwide beta (excluding Japan), which would begin on February 4 and conclude on February 11. An exclusive emblem for participating and a wallpaper for providing feedback were confirmed to be a part of this beta as well. All of the content appears to be identical to the Japanese beta as well.

Theories
One theory generated during the teaser campaign was a new game based around the time of the Estovakian Civil War, due to the first teaser message likely referencing the fall of the Ulysses 1994XF04 Asteroid and the Civil War, and the third teaser message referencing the Kottos airship. Another theory involved a remaster of multiple Ace Combat games at once, due to the various references to different games, including the Ulysses, Kottos, and Edge.

A discovery made on July 16 was that the teaser radio transmissions included a countdown. "Here comes the third strike" involved a 3 and "All engines on Kottos 2 destroyed" involved a 2. This was confirmed the next day, as the message "Ridgeback One. Edge, report" involved a 1, leading many to believe that July 18 would have brought a trailer or announcement of some sort.

Around the time the teaser website, NewTitle, was set up, a second teaser site (titled "NEW TITLE") was created by Namco Bandai for another title. Many theories surrounded this second website's possible link to the Project Aces website due to their simultaneous launches, but this website was eventually announced to be teasing Jump Legend Biography, a Nintendo 3DS game compiling certain Famicom and Super Famicom games.

Trivia

 * Teaser 00 makes two references to , a 1983 arcade game developed by Namco. The unknown female humming in the beginning was humming the Mappy theme song, and Mappy himself appears as a silhouette on a pair of wireless headphones.
 * Interestingly enough, Ace Combat Infinity launches in 2013, which is the 30th anniversary of  Mappy' s release.
 * Infinity is running on the same (or an upgraded version of the) engine that Assault Horizon utilized, as evidenced by the oil splatters on the screen and the explosion effects.
 * September 19, the day the Ulysses Disaster trailer was revealed, has symbolic meaning to the series. Operations Umbrella and Autumn Thunder both took place on September 19, as well as AWACS SkyEye's birthday.
 * The Infinity symbol from the trailers bears a resemblance to the Mobius Squadron insignia, adding to the rest of the evidence that this game was heavily inspired by Ace Combat 04: Shattered Skies.
 * Ace Combat Infinity appears to use similar, if not exact, squadron animations from Ace Combat Zero: The Belkan War, as seen in the trailers. For example, at the end of the Ulysses Disaster trailer, an aircraft squadron is seen separating formation in a very similar, if not exact, resemblance to how the Silber Team separated formation after making their entrance.
 * The Ulysses Disaster trailer also features a few hints to the COFFIN system:
 * at the beginning, while loading the elements of the main menu, "establishment of neuromuscular connections" is mentioned as one of the things being loaded;
 * as the Ulysses asteroid is being explained a few seconds later, the video zooms in on a hexagonal pattern very similar to the ADF-01 FALKEN's cockpit;
 * "COFFIN IN/SYS" is visible in the top right (above an unlit "NORMAL" and a lit "ONLINE" indicator) before the video zooms in;
 * and for a split second, closer to the end of the video, the back of a woman's neck is shown with some sort of digital diagram on it, similar to the ENSI ports used by Rena Hirose in Ace Combat 3: Electrosphere.
 * There are quite a few Trojan references in Ace Combat Infinity as shown by the Ulysses Disaster trailer:
 * The terrorist group, Sons of Troia, uses an alternate spelling of "Troy";
 * Ulysses is an alternate spelling of Odysseus, who had the idea of a Trojan Horse;
 * Stonehenge is built in Turkey, the original location of Troy;
 * The Ulysses asteroid is a Jupiter Trojan.
 * During the beta in November, Goodfellow mentioned that Comona Base is known as Area B9K, but the briefing map displayed Area B7K. This was corrected in the beta in December, where the briefing map now shows B9K.
