ARDefender - to feel the fullness of this game, you only need to print a specific sheet and then the reality of your reality will become virtual or Vice versa. The point is that thanks to the game and the camera of your phone, your desktop turns into a real field of battle. It appears defensive tower and a lot of enemy units, crawling and moving in the direction of the tower. All you need to do is to move the phone (moving the camera phone has value) and to destroy all nasty! Try it, it's so fun and cool! And most importantly unusual and will appeal to others as much as you do!
