Air Combat Codes and Secrets (PSX)

Air Combat is a semi-realistic flight-sim/action game; it was developed by Namco and was released in 1995 for the Sony PlayStation. It was called Ace Combat in Japan, but the name was changed for the overseas versions for unknown reasons. It is part of the Ace Combat series. The story begins when a terrorist force starts an uprising and inflicts massive damage across an unnamed country. Efforts to defeat these terrorists through conventional means failed and the situation turns desperate; in response, a mercenary air force has been assembled to take the fight to the enemy and free the nation from the vile terrorist forces.

Air Combat is mostly considered an "Arcade Style" flight game due to its semi-realistic physics and the fact that many planes can carry (nearly) 40+ missiles. The goal of the game is to destroy enemy targets dispersed throughout the various levels and earn money (something that continues with the current Ace Combat games) there are non-target enemies that the player can also destroy to earn some extra cash. The player can choose from several different planes in the game ranging from F-4 Phantoms to Su-27 Flankers and Stealth Fighters; optionally, the player can select a wingman to accompany him or her during a mission, and can "instruct" the wingman to perform one of three actions;
