Defend the planet from pesky aliens in this fun shooting game. Use your mouse to aim your missile by hovering over where you want the projectile to explode and then press a, s, or d to shoot. You've got to plan ahead and try to figure out your timing because the missile won't cause any damage until it explodes.
How to Play:Hold the mouse over the point where you want your missile to detonate. Then use the 'a', 's', or 'd' key to fire the missile from one of your launchers. At the end of each round, you get extra points for unused missiles. At higher levels you will receive more missiles, but the alien ships will advance more quickly and in greater numbers. The game ends when you lose all of your cities or all of your launchers.
