When you purchase the Full version, our game is complete, with 15 stages to play and 10 different aircraft. The locked icon appears on a stage orplane that has not been unlocked, it unlocks when player advances through the stages, which means that all planes and stages are already in your app. There is no need to buy anything inside the game since you already have the full version, it is 100% complete. Just play and advance through the stages and new planes will be unlocked! ;)
Having said that, pictured here, there are three categories or generations of combat aircraft available: 1) starting with third-generation jets (like the F-4, F-5 etc), 2) the fourth-generation (F-14, MiG-29 etc), 3) and finally the advanced fifth-generation fighters such as the J-20 and the F-22 Raptor. Notice also that each generation has a different color code for the icon.
However, if you just bought the game because of some specific airplane, and you want to fly it right from the start, we added this handy "cheat code" which can be accessed by
going to the OPTIONS screen (second button from left to right in the title screen), and then locate the ATMOSPHERE EFFECTS OFF button, like shown below:
Press this button repeatedly, at least 10x, until you hear a different sound between the normal clicks of the button pressing. This sound means that a third pilot profile has been
activated in the pilots profile screen. This third profile has 5 million credits and all airplanes unlocked from the start. Have fun!
