Unlock All Aircraft and Campaigns
Input a code at the title screen to unlock most of the features of the game--including aircraft, campaigns and paint jobs. Press and hold the "+" and "-" buttons, then press "Left," "Right," "1," "2," "2" and "1." A message will appear at the top of the screen denoting the items unlocked.
God Mode
If you want to be indestructible and all-powerful, try the God mode. Pause the game. Press and hold the "-" button and then press "1," "2," "1" and "2." Input this code during each mission or mini-game to access God mode.
New Airplanes
If you would rather earn your airplanes the hard way instead of with a code, unlock one new airplane with each mission you complete. To get the second unlockable airplane, you must beat each mission with a ranking of veteran pilot. This requires three stars during a mission.
Mini-Campaign Bonuses
Unlock the mini-campaigns Bombing and Dogfighting when you complete Campaign mode. Each of these campaigns has six missions. Two more aircraft are unlocked when you complete the missions. You will receive weapon upgrades by finishing both mini-campaigns.
