Following is a list of unlockables and secrets in Air Combat.
Loading Screen Cheats
The secret loading screen can be activated by holding R1 and Circle buttons each time before entering loading screen. When entered correctly, the loading screen will appear as a black screen with bouncing discs instead of the usual Phoenix logo.
During this screen, a key combination can be entered to enable a cheat function. Once the key is successfully entered, an icon from Namco's classic games will appear to the bottom left corner of the screen to represent its effect. Bear in mind when using this cheat, you have a limited amount of time to input the codes. The amount of time remaining is proportional to the amount of CDs on screen; The fewer CDs on screen, the less time you have.

The secret mini-game will replace next loading screen after its cheat input has been entered until the player enters secret loading screen cheat to revert to secret loading screen. In this mini-game the player must destroy as many bombers and missiles using a Phoenix logo before the little chick at the bottom walks from left to the rightmost corner of the screen. Enemy spawn direction is randomly assigned each time the mini-game is started. The missile rarely spawns, but has more points than a bomber.
The Phoenix can be controlled using either Left or L2 to move left/counter-clockwise, and Circle or R2 to move right/clockwise, its control method (circular or diagonal) can be changed by pressing R1. Should the player managed to reach end score of 4.70 points/second or higher, a congratulatory message will appear at the end of the mini-game, and the player will be awarded with free aircraft purchase cost and wingman hiring cost.
