Different in style is the best word for this game. This defense game using different way to defense the tower. It not use gun or army. All what you need is only your mouse speed. To kill your enemy, you can pick their head and get it up then drop it. Yeaa.. You just need to drop them down. Remember to drop them from the very high place or they will stay alive. As usual, you can also upgrade you tower using gun, but this not the major weapon. The major weapon is drop them with your mouse. FREAK!!
