Customer Reviews

This turned out to be a great game

I love tower defense games and I purchase many of them. This game game was fun to play and I actually could play it all the way through without spending a lot of extra money like a lot of other games. It's well balanced. I only wish that there were additional levels of play. I would pay for an additional game pack. You will be surprised at how easy it is and how fun it is. It's one of my top ten tower defense games. If you love tower defense, GET THIS GAME!

Top of it's class

I don't agree with those complaining about it being too difficult without using bombs. I've gotten through every level on 'normal' setting without the use of a single bomb. Try using your brains. If you want a victory just handed to you without thinking it through, you shouldn't be playing a 'strategy' game to begin with. You won't find too many other TD games with more polish than this.

A great tower defense strategy game

I got this game when it was offered for free quite some time ago and have just gotten to finishing the Adventure mode. I have to say that it was a great game with a good variety of weapons, challenging (but not too difficult) maps, and deceivingly cute enemies. The game is well designed and polished. I'm running it on my iPod Touch 4th gen with iOS 5.1.1. Thanks to NCsoft for fun game. Now on to the Endless mode!
