Castle Frenzy for iPhone

Gameloft has done a great job with Castle Frenzy. There are tons of different ways to kill enemies, lots of cool upgrades, very nice graphics and animations, great sound effects, and lots of overall polish. There are 23 achievements to earn, and you can compare these with your friends via Gameloft Live. Couple that with the Survival mode and Castle Frenzy has quite a bit of replay value. If you like castle defense games this is one you'll want to own and it's only $2.
