A trainer would be nice, but I doubt it, the games only in alpha stage right now.
The best things ive managed to do so far, is give myself massive amounts of dust and make the heros you get be uber powerful.
This means you get massive boosts to the plants/fleets you have heros on, and enough dust to make their upkeep minimal, and makes you able to complete constructions in 1 turn, because you can buy out the turns with more dust.
I played around with research, but its more tricky, each new turn the value tries to reset, ive tried overall, and planet wise. I managed to temporarily get the value high, which allowed me to do 2-3 in one turn that should have taken 10 or so, but it didnt stick, and it got tiresome, finding new values each time.
Your best bet is with the heros, when they are maxxed out, they give massive boost to all resouces, building costs, times etc
yep hero xp is easy to find
lvl 20 seems to be max
do a search for exact value , value type float
