Flash Game

I'm looking for the name of a Flash Game I played years ago. I guess you could call it a strategy game. Basically you had your base and had to destroy enemy base, you would start deploying cavemen either with sticks or slingshots. You would then after a number of points do a "human evolution" upgrade and you would have knights, musketeers, us army soldiers and last were like some robots or alien things. You could also have turret things at your base or castle whatever it was.
