Mini-nuke launched?! Fallout sucks! Shotguns?! Try something bigger! Electronic Munitions Launcher (EML; aka, a rail driver)?! You'll get yourself electrocuted! I say, if you want to go all out, then there's only one gun! M-134! 'Nuff said!
What is up with everyone trying to one up the shotgun? Its cheap and effective and people would probably hurt themselves more than the zombies with anything else, or not be able to find rounds for it consistantly lol
