Anomaly: Korea is a reverse tower defense — or tower offense game, the third in the Anomaly series. This time you have to defend Korea from the Aliens. You control a squad, and have to gather resources (needed to acquire new units) upgrades and power-ups, these capable of being used for a limited time span, while selecting the best route to attack enemy towers. The gameplay is a blend of strategy and action since it is real-time. Action is viewed from a top-down perspective. New to the series is the Art of War mode, a set of six missions which add to defeating the enemy tower specific objectives, a time limit, and a higher degree of challenge.
