Ace Combat Infinity

Ace Combat Infinity, a new Ace Combat game, is currently under development by Project Aces. The game is confirmed to be on the PlayStation 3, and appears to take place on Earth.

Plot
Ace Combat Infinity seems to take place on Earth once more. However, unlike Ace Combat: Joint Assault and Ace Combat: Assault Horizon before it, Infinity seems to bring events from Strangereal into the real world. During the teaser trailer video, shots could be seen of various set pieces from Strangereal, such as the fall of the Ulysses 1994XF04 Asteroid and a facility bearing similarity to the Stonehenge Turret Network. The roundels on one group of the ASF-X Shinden IIs that were spotted bore the initials of an unknown group, the UNF.

Aircraft
So far, the only confirmed aircraft for Ace Combat Infinity are the CFA-44 Nosferatu, PAK-FA, Su-35 Flanker-E, and the aforementioned ASF-X Shinden II, as seen in the trailer video. However, one moment of the video shows missile silos that look almost identical to those of the P-1112 Aigaion Heavy Command Cruiser.

Teaser campaign
The project was first teased on June 14, 2013, when Kazutoki Kono (who directed Ace Combat: Assault Horizon and worked on numerous other Ace Combat games) 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 letters in "fell" were formatted differently, putting more emphasis on the "ll". 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.

Hours after the "closening" post, 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 it.

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 repeated in both Japanese and English  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 repeated in both Japanese and English hours later on the Project Aces Twitter account.

On July 17, the image was once again replaced with a friendly radio transmission, this time reading: "<< Ridgeback One. Edge, report. >>" followed by the Japanese and English 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 what looked to be a squadron emblem, consisting of at least two human bones possibly forming the letter A.

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 PM 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 for what was now confirmed to be a PlayStation 3 game, titled Ace Combat Infinity, was added to the site.

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 bring 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.
