Forums → Games → WHAT IS THIS GAME CALLED?

I played this game like 5 years ago. I will describe all i can so please tell me the name of this game if anyone knows. All i remember is: You would look at towers to put down on the map, but units would come out of the tower. For example, a knight, a archer, a minotaur, a skeleton, stuff like that but way more. Then enemies would come and try to get past the defense. Your units either defended or attacked and defended I don't remember. There was definitely a screen to upgrade your units to make them stronger. There was also a map to pick what level you wanted. I am 60% sure that it is on armor games. If you know what game this is and it is or isn't on this site, PLEASE let me know. I REALLY want to play this game SO BADLY. IT WAS SO FUN. PLEASE RESPOND TO THIS QUICKLY!!!!!!!!!!
