Check out my “Fear the frigate fleet!!!” on challenges. This setup for large maps seems to work nearly everytime, except for once, but i think that was because my enemy modded because he had an entire force of bombers, me fighters, and NOT A SINGLE ONE DIED. they could not die.
If that isnt cheating then tell me what is. i had to beat him by killing all of his cruisers.
Back to the point, these, as i call them, “Close range pounders” have good enough shields to live until they get close, then just blast you away into oblivion. See if you can beat the setup without invincible bombers. then tell me what you used, so i can counter that
