Tower Defense is a free online strategy game. Fight against hordes of wicked invaders and eliminate all of the attacking waves as fast as possible! Start by choosing available towers and placing them on or along the path. They will launch shots to cause damage to the foes and drain their power. To win sooner, you should purchase upgrades with the money that you earn during the previous match. Be careful! Do not let too many opponents escape from the end of the track!
