I need tips on how to keeping a low score
Anything would be nice i already know that when flying a fighter/attack plane you should put it on attack it will keep your fighter score lower but is there anything else i can do
The most important advice anyone can give a new player is don't play for score or rank as score/rank are meaningless.
I know that you think by having a low rank will mean you're good at the game but all it really shows that you are good at
gaming the game and that's it. That little nugget you posted about scoring your fighter sorties under attack to keep your fighter rank low is just an example of how you can game the game and does not in anyway indicate your level of skill, in fact, it usually points to the opposite.
Do yourself a favor and start playing the game for the fun of it and don't worry about what your score or rank is, no one else cares.
