Steampunk Tower is a tower defense game with several unique mechanics. First, there is only one big central tower on which the various cannons are purchased and placed. Second, the central tower gets higher as the game proceeds, so there are more floors on which to place your cannons. Third, you can move your cannons around on different floors and/or change their orientation. Finally, you can upgrade your cannons and play additional challenge levels. These will test your tactical skills but will also reward you with many extra points!
