Desktop Tower Defense 1.5, also known as "DTD1.5", is a tower defense game with a desktop theme created by Paul Preece. This was one of the most popular games on Kongregate for several months after it was published. It is an upgraded version of Desktop Tower Defense, one of the first tower defense games that gave the user control over the maze by letting the player place towers on the same map that the enemies walk on. The graphics, audio, and the interface have received an overhaul since the original version. __TOC__
