I like the newist version of that game, the one with a different map, I go to the platow in the top left corner of the screen where there is a 3 bar common a 1 bar common and a 3 bar rare, and there is only one way in so defence is easy
the eden coloney on the right never develops, and the one on the lower left (right below my base) fully develops, but concentrates all its defences on a spot where you cant even come in lol, while leaving its top completely undefenceless
I love just sending in starflares into there tokamoks at the right base (theres only lazer lynx there, and they never build more) and into the geo plants in the southern base (they are completely exposed) cutting off all power, so they cant build an army, so then, when Im ready, i just send in about 20 lynx and finish them off lol
this works even in hard lol
new maps are easy
