Kingdom Rush Frontiers
A long time ago, there was a great battle between good and evil. The battle was fierce and many warriors gave their life, so that the people would have some peace. Since then the whole land was peaceful, however, the evil came back and this time, they are more powerful than ever before. The idea here is to defend the kingdom. You need to erect some towers to do just that. You would have a hero in this game, which is more powerful than any of the soldiers. The hero can level up, but the other soldiers won't evolve. You can replace the hero if you have other heroes in your list.
