This is a description of the use of the Shangri La 'wonder weapon' 31-79 JGb215, also referred to as the Shrink Ray or Babymaker. Pack a Punched version is called The Fractalizer.

When you fire this weapon at the zombies, it makes a group of them really small and wimpy. Simply run over them to kill them, you will take some minor damage as they do less damage when small. The effected zombies will grow back to normal size in a few seconds, but will remain weakened so a simple Bowie Knife stab will take them down on higher rounds. You can use this on the fire and wind zombies to easily take them down as well.

Once PaP'd, the weapon is much more formidable. Now you want to get a zombie train following you, aim carefully at the entire line and fire once, it will make them all tiny, instead of a small group. This takes out so many zombies for so little ammo and has no trouble on rounds 30+.

I wasn't sure what to make of this weapon at first, but it is one of the better wonder weapons out there: it won't hurt you and has a fair amount of ammo so it usually has a good amount left whenever I get a max ammo.

Happy babymaking!
