Play Tower Defense Old online for free

Tower defense is an HTML5 strategy game where the goal is to defend your territory by placing defences from the enemy's attacks. You can protect your territory from the attackers by putting the right defensive towers on or along their path. You can purchase the defences at the shop, but you need to have enough money to be able to do that. The stronger the defense towers, the better, but it will surely cost you a lot. But, the amount that you will be spending in upgrading your towers is worth it because the enemies will also upgrade and will be much stronger as time goes by so make sure to have enough money for you to be able to upgrade your existing towers. Don't let these crazy enemies attack the peacefulness of your kingdom so make sure to plan your strategies and successfully finish each level carefully.
