Ace Combat Infinity/References

Ace Combat Infinity features the most references to past games of any game in the Ace Combat series, from numbers to names to aircraft.

Ace Combat 2

• Slash and Nagase, the flight lead and second-in-command respectively, of Ridgeback Squadron are taken from the callsigns of John Herbert and Kei Nagase.
• The XFA-27 returns as a playable aircraft.

Ace Combat 3: Electrosphere

• A diagram of ENSI cables plugged into the back of a woman's neck was seen during one of the game's trailers.
• The R-101 Delphinus #1 and X-49 Night Raven return as playable aircraft.

Ace Combat 04: Shattered Skies

• The Ulysses 1994XF04 returns as the 1986VG1 Ulysses, whose impact event on Earth is known as the Ulysses Disaster.
• Task Force 118 uses the same number as Mobius Squadron (118th Tactical Fighter Squadron).
• The X-02 Wyvern returns as a playable aircraft.
• AWACS Sky-Eye takes his name from AWACS SkyEye.
• Stonehenge returns, albeit with some changes:
  • 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.

• A Scinfaxi-class submarine can spawn at random during Mission Updates.
