The game starts off very simply, but later opens the floodgates so to speak. With the firing of your defensive towers try to capture the attacking end of the lines with laser explosion. Beware whether you hit on the right end of the falling invaders, otherwise they are not neutralized. The game resembles Missile Command from the eighties of the twentieth century. Use the mouse to control aiming and the left mouse button to shoot. Number key one, two and three to change position of the active tower. The game offers a very fast pace and high quality dance music as accompaniment.
