Mini strategy online game. Army of Ages is an evolutionary strategy game that pits you against alien invaders. You begin the game in the Stone Age, with just a base and some money. Select your base to view the available building options and spend your money wisely. Buy buildings that will spawn offensive units and gatherers, as well as turrets to bolster your defenses. You can upgrade your buildings so that they produce more effective units and spawn them at a faster rate. As you battle the aliens, you will gain experience. When you have enough experience, you can evolve to the next age. Evolving will strip you of all your buildings and units from the previous age, but will allow you to build improved structures. Don't forget about your special attacks; you gain a new special in each age.
