Sorry for bumping an old thread, but I've come back to this game many times.
Unfortunately there is never going to be plans of a trainer or release of cheats for Imperium Galactica II.
You can activate the console in-game by pressing '~' but it is only used for debugging you cannot activate cheats using it.
Sorry.
You can CoSMOS the fighters.Just have a planet build auto send them a bit away from the planet wait till you got about 9 or so them split them up have CoSMOS look for the fighter you split off.You can then change the amount to about 25,000 fighters and sell them for max money.Easy to get over $100 million that way.
