Use the mouse to shoot at the invading aliens! Press any keyboard key to reload, and move your mouse to the bottom of the screen to enable your shield, which will protect you from the red aliens' attacks! If an alien touches you or you're hit by a red alien's laser, you'll take damage. 3 hits and you're out!
