I think that's more your GM's error. I've run modern zombie campaigns and never had these issues. Sure, there's advanced tech. Electricity would realistically last for a little bit. To use technology, it takes more time that you have. If you plan beforehand, sure that's okay. You could do that in the 70s. There were maps and the yellow pages. If I want to find out where a gun store is. It takes me about two minutes. Those two minutes could be life or death, at least, if I'm the GM. That's on WiFi as well. Try it on 3G, with zombies, and low power. I remember being in downtown Manhattan trying to find directions and that taking about ten minutes. I have the old iPhone 4, though. That is if this is all still up. Going off from what's here , " The core systems of those infrastructures are under supervision pretty much 24/7. There are always issues that need to be addressed and maintenance that needs to be done regardless of all redundancy. " All these factors dependent on the world and how it's collapsed. Which, again, all comes down to the GM. I don't like setting the game right when the apocalypse is happening anyway. Somehow you're in it, deal with it. /rant. I'd GM! I already have a player from another game interested in me running zombie campaign. So that makes two? EDIT : Finding information is easy. Finding correct and useful information is difficult. Also consider that Internet is not always as helpful as expected. Most of the time the popular results show up. If they're popular, they're likely picked over. I've found the Average Joe is rather bad at finding stuff on the internet, anyway.
