If you're into traditional tower defense games, then you'll be excited to see Total Defense 3D by DaSuppa is now available for Windows Phone users. Sure, the game came out two years ago on iOS and Android, but the important thing here is the developer is now taking on Windows Phone (they've also brought over Tetdraw, a new twist on the classic Tetris).
Total Defense 3D is what it sounds like, a 3D game where you spend your time placing weapons on a map, taking on the hordes of enemies that come in waves. What makes Total Defense 3D a lot of fun are those 3D graphics, as they're outstanding. Players can also use two-fingers to pinch to zoom, rotate and pan the screen, giving a whole new view of the classic style gameplay.
