Har du alltid drömt om att vara en superhjälte? Har du alltid vill flyga i himlen och rädda människor och sånt?
Have you always dreamed of being a superhero? Did you always want to fly in the sky and save people and stuff? Well, in this case you're in the wrong house, but if you feel like a super-villain, you rang the right Bell. Tower defense: this wonderful and beautiful operation, which is superheroes, has all kinds of crimes. We have banks to rob, we blow up buildings, and all we want from you... is to defend us from a slightly angry and potentially deadly aggressive army of superheroes ... It's easy, isn't it?
