Cybertron Design Studios has released a playable demo for Towers of Altrac, a tower defense game that promises beautiful 3D environments, spectacular effects, a dynamic weather system, day and night time cycles, and more. The lands of Altrac are invaded by the Morkul'al and it's up to you to defense against the enemies. The lands are divided into three folks: The Dreoks, an engineering nation of humans. The Eldran, a forrest nation and the Kal'than, a magician nation. Each nation has an own campaign to go through and free up the lands.
The player will battle against over 50 different enemy types with different levels each, 15 boss types and 15 elementary enemies. As the maps progress, the enemies become stronger and more difficult to defeat. Towers of Altrac has 62 unique environments, each with a different placement of roads, tower build locations, and open areas to plan a strategy around.
