F-14 Tomcat Codes -

Flying cars:
It is possible to replace the jets with flying classic cars. Something can be done in novice mode at level 6 that will result in a constant tone until you get to level 7. Level 7 will then start with classic cars flying at you instead of jets. The level passwords with cards are identical to those with jets. You must duplicate some sort of game condition (complete all the first six levels with no damage? Complete level 6 with no damage and using only one plane?) to unlock the cars.

Note: There are 20 basic levels in the game. Level 21 is a repeat of level 1, but with UFOs instead of jets to shoot down. The password at level 22 is the same as level 2. You must enter the password for level 20 or 21 and play the game from there to get UFOs instead of MIGs. Entering level 21 in Ace mode gets you started all over again from level 1, but with World War I era tri-planes instead of jets or UFOs.
