Super Heroes Tower Defence

Tower Defense games are awesome but have you ever played a tower defense game where you got to use your favorite superheroes as your tower defenses?  In Super Heroes Tower Defence you get to set up your tower defense units with powerful heroes like Superman, Batman, Spiderman and many more.  The creeps that are trying to take you down are also some of your favorite, or most hated, villains like  The Joker.  Use your best tower defense strategy so that you can defend your city from the evil that is attacking.  The more villains you kill means you will earn more mana which can be used to buy upgrades for your Super Heroes Tower Defence.
