Just when you thought you were done with Tower Defense games comes an exciting new one from Critical Thought Games. geoDefense [App Store, $0.99] is a retro-inspired version of the game that offers some wonderful touches to the genre.
Like The Creeps, geoDefense offers set paths on which the enemies ("creeps") traverse to get to your base. Your job is to set up tower defenses to destroy the oncoming waves of enemies. There are 5 tower types with 7 upgrade levels each.
The graphics and animation included in the title offer a wonderful arcade-y feel and are a surprising touch. We recommend checking out the video embedded below.
