Idle Tower Defense combines gameplay from idle games and tower defense games in a unique and refreshing way! It will appeal to fans of both genres. There are several tower types available, ranging from regular towers to dual ones. You have an unlimited number of lives, so don't worry about any passing monsters. Each wave has a boss which you need to kill in order to move to the next wave. If you fail, the wave restarts. You can only have one instance of each tower; after a tower is built, the power and cost of all the remaining towers increase. Get damage bonus and equipment after your towers kill a certain number of monsters.
