Astral Tower Defense is a Pardus-themed (see www.pardus.at) tower defense game, in which you must try to defend your homeworld from attacking space creatures by purchasing and upgrading weapons and special equipment. Instructions and tips are available at astraltowerdefense.com for those not familiar with tower defense games.
To the greatest extent possible all graphics were taken directly from Pardus, and using the Pardusian Conv/Bio/EM armor and weapon properties gives Astral Tower Defense a unique twist. A few other features include lots of maps to choose from, 80 different creeps with various special abilities, a "Hall of Fame" in which you can record your high scores, over 50 different upgrades, and more. Additional maps and other minor improvements will be added as time allows, and plans for version 2.0 are already in the works!
