All aircraft:
Use the following steps to unlock all aircraft, including
special colors. First, acquire an aircraft by destroying it
in battle. This is easy, except for three aircraft. Forget
the ground targets and dogfight instead, which is the true
nature of an ace. You can acquire three different paint
schemes for each aircraft. Two of the paint schemes can be
acquired by destroying that color aircraft in battle. To
acquire the special brightly colored third aircraft, you must
find and kill the pilot flying it. On each level of the game
there is a single hidden aircraft (eighteen total hidden aircraft).
Each one of these aircraft has a specific pilot. When you see
the aircraft in front of you and lock on, it will display the
pilot's name next to the aircraft name and lock on square.
For example, "S-37A SMIRNOVA". The hidden aircraft will not
show up on radar until you get nearby. On radar, the aircraft
will be marked with a red triangle instead of yellow.
Each hidden aircraft is always in the same place on their specific
level. This is always in an empty spot on the map away from the main
combat zone. The aircraft can usually be found directly behind the
main combat zone. Last but not least are the three remaining aircraft.
To acquire the Yellow Squadron fighter (SU-37) of your nemesis
Yellow-13, you must kill all of the pilots with names flying the
special colored aircraft (eighteen total).
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.
