Only you can save mankind

As the mightly alien fleet from the very latest computer game thunders across the computer screen, Johnny prepares to blow them into the usual million pieces. And they send him a message - We surrender. They're not supposed to do that! They're supposed to die. And computer joysticks don't have 'Don't Fire' buttons. It's hard enough, trying to save Mankind from the Galactic Hordes. It's even harder trying to save the Galactic Hordes from Mankind. But it's only a game, isn't it?
