The game will have a free-to-play version, as well as a premium version for any intrepid tower defeders who want to truly test their mettle. The free version will differ from the paid one in a few ways, most of which being cosmetic. However, there are a few gameplay differences. Those who play can defend an additional four areas, for seven total instead of three. There are also some hosting options, as well as dyes to make your towers extra sexy.
