I keep telling everyone; the way you take care of zombies is shotguns and flamethrowers.
i agree with the shotguns, not so much the flamerthrower. Depending on the type of zombie, you might just end up with flaming zombies attacking. that's an upgrade for them.
with 40k its best to get the rules straight then apply imagination and rationalize; you will only get annoyed doing it the other way round
