and a good tip , onwhen you conquerer normal regions the first you put green giant , then the following 5 military research then each country you put a green giant mark.keep the last hostyle country alive til you are sure that your defense is high enrough (green giant)
set them on the upper region ,the highest left country and that middle country.use the strategy 'speed' each time you attack them.use lots of snipers!
sorry for double post
the easyest way is: firt upgrade the alied units , then canon then shield.
if you're good in this you well git this before enemy upgrade.reupgrade evrything besides engine , now attack the suns ,the 4 outwards get that before the brown balls. upgrade engine and alied untits , now you're spacecenter is under controle. reupgrade engine and attack 4 middle suns , then reupgrade shield and attack the rest. if before the white balls you alieds are maxed and all suns are out you can even stand and watch your alieds do the rest.
