How to get paid Autobots for free: look for the address autobot_infinity change it to 255 i also change the value of arrowNum to max 9.
You can also change the levels of your soldiers and hero gens by doing simple search.
Soldiers lvl i think can only go to 99 w/o FC.
Hero lvls i tried to go to 99 also only because the higher the lvl the more you pay to summon. Im sure it can go higher than 99. Enjoy!
