geoDefense Swarm is a Tower defense game available for iOS. It is a sequel to the original geoDefense game, released by Critical Thought Games in 2008.


Over 7 defense tower types can be purchased by dragging and dropping them onto the map. Amount of dollars earned are dependent on which enemies are destroyed. Later levels include the new addition of vortex towers that can be linked to defense towers that increase damage.


The game has three difficulty settings with 10 levels each. Each level consists of several waves of enemies attempting to make it across each map. Maps vary across stages and include preset obstacles and pathways that can either impede or increase enemies speed.

Downloadable content levels were released that include 5 new medium levels and 6 new hard levels.
