is it possible for there to be a new maps or at least something new to add on to a map? the idea of a defense on a minor scale of a solid square is vary basic and was wondering has anyone expanded this idea of taking the concept of a square and designed flavor to the map? like a roof of a skyscraper and have the zombies come from the sides like they where claiming the building or a crossroads a middle of a city or just simply put embers and ask effects as a mod to give the player imagination of whats happening outside of our view in the defense square/playable area. I know this game was meant to be simple and arcadic and not every game has to have a story or immersive backdrops. but the idea of a square could take the phrase "think outside the box" to a whole new meaning. especially since the who point of the game is to build a box like defense where you keep yourself in and keep zombies out...
