It`s kind of evolution of the erlier version. Buy uzi, buy flamer joe max range. Focus only on the jeeps and harder units. Buy shield generator and laser tower. Buy S.C.A.R. Max the towers (I maxed all, but I think, that Fl.joe needs range only and laser fire rate only. didn`t check :P) max the wall too during upgrading towers. (I was upgrading those wich had the lowest price). Buy old glory. Buy about 50 gunmen. Sell Fljoe and laser, buy 2 shield generators and max`em. Buy sattelite laser. Max old glory and sat. Every day after upgrading waepons buy gunmen or repairmen for the rest of the cash. This is the moment when the game is becomeing a little borring. Focus only on the tanks. When those big bad black robot appear, use sat. Remember to reload sat just after killing (need 5 sat rounds and few glory rounds ). The rest will be taken out by gunmen.
