Ace Combat 4 Cheats

Unlock the tiger striped F-4E
You can also get the tiger striped F-4E by completing the game once under any difficult setting, then using the sp. Continue option.

Alternate colors
Successfully complete the game in ace mode. Note: You may also need to obtain S-class for all missions.

Alternate opening sequence
To see a different plane other than the F-22 flying lead at the opening, go into a mission or free flight and choose a different plane. Crash your plane or quit the mission and return to the title screen. When the opening sequence plays again, whatever plane and secondary weapon you selected will appear instead of the F-22.

Preview airplanes and weapons
When you are in the hanger looking at the airplanes or weapons, hold Square. You will be able to look all around the airplane or weapon.

New multi-player levels
When you complete the game in any mode, you will unlock three more multi-player levels.

Safe Return
Easy completion: There are about eleven balloons ahead of you, up and down and to the side slightly. Then, turn right and go until you cross a mountain, four to six balloons later. Then, turn right again. Blast balloons until time runs out. It is possible to get an "S" rank under the ace difficulty setting using this method, with just balloons, not counting the planes. When you start the mission, your radar will have blinking dots all around. The dots are actually the blimps and not the noise. This will help find the blimps' location and hopefully increase your score.

Shattered Skies
Shoot down SR-71: In the "Shattered Skies" mission, the fast moving plane you are locked onto when the mission first starts is an SR-71. You can shoot it down by heading towards the back of the combat area and climbing to about 30,000 ft. Head it off and you should be able to shoot it down. Quickly tap the Analog-stick Down as the mission starts. If done correctly, the SR-71 (which is the orange triangle) should still be blinking. This is the chance to get the Sr-71. Using the X-02 is recommended, due to its powerful speed.

Shattered Skies
Yellows leave early: Hitting a Yellow early will not kill them, but may make him and other Yellows leave the area early, after he gripes about being hit.

Shattered Skies
Radio transmission: Do not bother going after the Yellow Squadron fighters. They are nearly impossible to hit. If you do manage to get enough hits on one to qualify as a kill, it will not go down. Instead, a red radio transmission will appear as follows. Note: You do not get any points from it. : Who was that who shot me? : It was a Ribbon fighter!

Easier X-02s
There is an easier way to get the three X-02s rather than going through the entire game. After the game is completed, the "Free Mission" option will be unlocked. Select this option and choose a difficulty setting (normal for the gray X-02, hard for the black X-02, or expert for the silver X-02). Select any mission to play on that difficulty setting. If you get an "S" rank on all the missions, the X-02 becomes available. This allows you to skip all of the missions you got an "S" on when you went through the full game. For example, if you got an "S" on all but three missions, you only have to play those missions instead of the entire game.

Easier ground battle
The best way to destroy multiple ground targets is to fly the F-15 Active using the FREB (fuel - air explosive bomb). This will destroy about six to ten targets if they are close together.

Easy kills
The best way to kill is to get in the cockpit view and go to work. When done correctly the kill will happen much faster and you will save missiles. If done in the HUD view or where you can see the entire plane, then chances are you will waste several missiles trying to kill enemies. Also use your bullets wisely to cut off paths of escape; this will assist you further. When on a mission and are "dog-fighting" in air-to-air combat, press Circle(2 ). When you do this, you will fire two missiles at the same time. This destroys your target immediately with two shots, rather than hitting it only once and still having the risk of it shooting you and your allies. While dogfighting in air-to-air combat, switch to the cockpit view. Lock on to your nearest enemy and fire a missile. Immediately after you fire the missile, shoot your guns. However, instead of hitting the enemy fighter, aim for the air in front and around it. The enemy fighter will try to dodge the bullets, thus steering into the missile's path.
