Customer Reviews

Like it Early On...

I have been playing tower defense games for a long time and this is pretty cool. There is a lot going on in this game which makes it far less passive than most. The upgrades for the hero are a fairly cool twist on the idea. It brings a touch of the D&D feel to the main character. I have tried several TD games lately and this one is by far the best I have come cross in quite a while. 4.9 out of 5 - after the first 4 maps that's a great score, I will come back after a few more to see if it deserves the 5!!! This game really is a challenge and I can't remember when I have failed on the early levels in anything in a long time... this game has a lot going on for a new player. Have fun!

Great tower defense

If you are wanting something different or new that is high quality buy this game!!

5 star Tower Defense

This is a very clever blend of several of my favorite tower defense games.
Well done guys.
