If you find yourself under enemy fire at work, perhaps from paper planes or elastic bands, stay calm. Silently remove the USB Missile Launcher from your desk drawer. And place it carefully on your desk. Once it is connected to your computer's USB port it will be fully operational. Use the radar screen that appears on your computer's display, to rotate the base of the USB Missile Launcher 360 degrees and adjust the trajectory of the missile flight.

When you have taken aim, and are happy that your target is unaware of their impending demise, click your mouse. With a noise that will easily be heard by residents of the neighbouring county, the missiles will launch. And your target will be left in no doubt who has won the war.
