[ WP ] It 's the zombie apocalypse , but the virus is n't spread through Bites , Blood , or Scratches .

It's over. The terrorists won. 
 
 They did n't win on guns or nukes. They won on a crueler method of war. 
 
 `` Stacy, come on. It's time to go.'' I hear Jeff calling to me. I guess he's right. It's time to go again. I put my gas mask on and head for the airlock. 
 
 The terrorists rigged `` dirty bombs,'' devices designed to poison or irradiate the area around them, with a bacteria that reproduces quick, and spreads quicker. They detonated them in key places in the world to poison the atmosphere. 
 
 `` You got the guns?'' I ask Jeff. He nods, and tosses me a shotgun. Our mission? Mass extermination. I double, triple check my gas mask, and follow Jeff into the airlock. Bryan, behind us, shuts the door, sealing the two of us in. 
 
 *Beginning Contamination Sequence, * says the computer. 
 
 It has been seven years since the bombings, but there are still plenty of ghouls to be dealt with. I see them out the airlock windows. They see me. They know: Fresh meat. 
 
 *Five, * 
 
 I take the safety off my shotgun. 
 
 *Four, * 
 
 I see the green gas that is Earth's atmosphere seep in to the airlock. 
 
 *Three, * 
 
 Jeff shoots me a wink through his mask. 
 
 *Two, * 
 
 He cocks his Assault Rifle. 
 
 *One. Contamination complete. * 
 
 My field of vision is fogged with the horrible green gas. The airlock door swings open. 
 
 `` Let's do this,'' I say, pumping my shotgun.
