Lots of Fun

This is a great tower defense style game. There is a bit of strategy involved with a lot of upgrades to choose from. I have a lot of tower defense games because they are my favorite ones to play and this game is in my Top10. Its more than just build a tower and shoot. If you want something that takes a little bit of thinking on top of a basic game you will enjoy this app. Dont listen to all the naysayers this game is a lot of fun.
