Oh noes! There's a zombie in your house! What should you do?
Sadly, a lot of people have seen so many zombie movies the first thing they'd do is go to their shed/garage and get out the chainsaw. Yes it looks cool, but is it really the best zombie-hunting weapon? Think about it. It's heavy, runs on gas and makes a lot of noise. Plus the signature mess might be a curse. After all, if infections spread through the blood, the splatter might be your undoing if you have a single cut on you.
The ace card of any zombie-hunter, then, is the shotgun. Remember, you're trying to remove the head or destroy the brain, and a shotgun is the best for that. Just aim at the head and shoot. Unlike what some video games make you think, the spread on shotguns (unless they have seriously short barrels) isn't that huge. It's perfectly acceptable to use it at medium range.
Anyone have any opinions? A car might be a better weapon. It can be used to take out a large number at once and to provide transport and shelter.
