Circuit Defenders is a fast paced 3D Tower Defense game, where your challenge is to defend computer circuits from attacking virus armies that are infiltrating the circuits via the communications port.

You have an assortment of defense towers at your disposal, and the ability to upgrade them as needed to ensure you can withstand the enemy onslaught.

Amazing built-in Circuits - Play any of the TWELVE circuits to play on, or go to the in-game user level gallery and select new levels from there to play, or use the in-game level creator to create and publish your own levels!
