Gameloft has just released another castle defense game for the iPhone and iPod touch, only this one allows you to defend your castle in full 3D.

Castle Frenzy, like all other castle defense games, will have you defending your castle by using any and all means available to you.  Like Knights Onrush, you are able to pick up and interact with the oncoming enemies, and like Monster Kill, you are able to draw shapes on your screen to activate spells.

The game features a campaign mode that gets progressively more difficult over time, but if you spend your gold wisely on some of the 18 different upgrades, you should be able to dispose of your enemies with ease.  Castle Frenzy also features a survival mode with infinite replayability.  And for those of you who are social butterflies, the game comes loaded with Gameloft Live, so you will be able to compare your achievements with your friends or even just do a little chit-chatting.

Castle Frenzy is now available in the App Store for $1.99.
