I may finish NLOWZSP some day, but it's not likely. In between my other Doom projects, I'm going to be working on a new zombie mod (much more organized, and slightly less ambitious/more manageable). The single player will be very story-driven (based off a community story I was part of a few years back), with some elements of open world gameplay. The multiplayer, however, would have to be unique. So I just wanna ask you guys what you'd want to see from a new zombie mod. And I get that there's a ton of these floating around in the forums, but "don't make a zombie mod" isn't an acceptable answer

So, what do you guys think? I'd like some RPG elements - quests, leveling up, etc. Would it be co-op based? Hub levels? One giant level? What weapons?
