Save as much money as possible then buy all four turret spots then buy two fire 
catapults one explosive cannon and one double machine gun from the forth age. do not
buy any infantry at all unless the enemyis at the large tree infront of your base. 
once you evolve to the fifth age sell all your turrets then buy four ionrays.
Nothing should get too tour base if you follow this correctly. when you have enough
money buy 2-a lot of supersolders then you will win the game!
