I thought Bailout Wars was enough for a good few hours. It seems that this isn't the case for Gameloft, who plans on releasing yet another castle defense game codenamed Castle Frenzy. This game pits you against knights in shining armor along with other types of enemies, totaling to around 10 different baddies to fling around.
Castle Frenzy also promises some of the best 3D graphics on the iPhone, and it definitely seems to show in the video. The production values seem to be a little bit higher than that of Bailout Wars, and I can only guess the price of this castle defense game being around $2.99.
Along with good graphics, Castle Frenzy will include 18 different upgrades, 3 of which are shown in the video. Some of the upgrades will include a griffin, a hydra, and of course the normal "fortify your wall" upgrade. While information is a little bit scarce at this point, I'm going to predict a mid November release if not earlier.
