When using the standard missiles, fire when the "Shoot" icon appears on the HUD. When used in dogfights, the missile will fly in a straight line to where it will make contact with the plane, rather than fly at it 6 o'clock and turn to stay behind them. If the targeted plane is flying right and you fire when the "Shoot" icon appears, the missile will fly off to the right, intercepting it along the target's flight path. The missile will also immediately adjust its flight path if the targeted plane veers off of their line. This works very well against evasive enemies, such as Strigon and Drones. You must aim the nose of your plane to where you can hit your target with your gun or lead the enemy (even if it is out of range) in order to get the "Shoot" icon. Even though it does not guarantee a hit every time, it will greatly increase the chances of making contact against mobile enemies.
The CFA-44 Nosferatu is very unstable. Using High G is useless as that will stall it out quickly. To prevent this from happening, never use High G. The best way to handle this plane is by using the throttle up and down separately.
A good thing to do against XLAA users is to attack them from above. These users are always at or near surface level. Use this to your advantage by going above 24,000 feet in altitude and strike from above. If you are using the CFA-44 Nosferatu, use its EML Cannon to take the XLAA users out from a distance.
If you have ESM control, have all of your battles be placed within the ESM range. Having ESM increases your missile capabilities and reduces theirs slightly.
If you are in a tight spot because the opposing team is using ESM, concentrate all of your fire on the ESM user. Do not worry about the other planes around you. As for the missiles, flying out of the ESM range will reduce its capabilities.
In Co-op Stage 2, there is a F-22A flying around after destroying half of the enemy forces. Its name is CERES.
If you are trying for an "S" rank, take the time to use Allied Attack and Cover to take out some of the UAVs that Pasternak uses to attack you and your squadron. After you have killed about five of the UAVs, concentrate your fire on Pasternak. He is always visible with ESM. This should give you an advantage. Later his ESM will disappear. Pay attention to your radar and use the Right Analog-stick to look around for him. If you are not trying for an "S" rank, use Allied Attacks directly on Pasternak so that your squadron keeps him busy while you take the shots on him. He always stops to fire his ADMMs; use that as an advantage to your Allied Attacks and missile attacks.
In Co-op Stage 1, after you have eliminated the ships out in the sea, a carrier should release the Strigon team. Use this time to have you and your wingmen take them out from the front or back. If you let them go, the fight will be a lot longer and difficult.
