The most worth waiting killer-level TD /Defense game in 2013. FREE to download!! No locked function!!! The story happened in an ancient and remote world. It is a chaotic era before the disappearance of the ancient magic power. Terran had established regulations for this ancient world, but Orcs had been eyeing on Terran’s civilized cities for long. They were ready to break the peace of the world. Finally, Orcs started war to Terran and quickly seized an advantage. Terran retreated step by step, and was eventually forced to hide in their castle. At this critical moment, Terran’s magicians found the secret of the Power of Elements on an ancient statute book, which can be used to reinforce the Guard Tower and fight against Orcs. The Power of Elements can even call supernormal powers, such as volcano, lightning, iceberg... The counterattack was about to start!
