Looks like a good start, but where's the spooky horrors?
I hope to make the spooky horrors more subtle and harder to notice, stuff that should dawn on the player over time instead of being shown up front. A server's players aren't idiots, so giving them the proper details to work with and enough time to drop small hints and nudges, they could figure things out on their own.
I think most people are desensitised to zombies nowadays.
The problem is trying to make zombies threatening. If players can dispatch a couple hundred zombies with a lead pipe then they're really not perceived as a threat. If ten zombies can take down an entire group of people easily, and with the threat of losing guns which will be a finite amount around the map, it might force players to be more cautious around zombies.
The idea is that no matter what, everyone is going to die and be a zombie at some point. The theme I want to beat into the survivor's heads is that survival is ultimately a futile effort and they're pretty much doomed from the get-go. As time progresses, resources will be spread thin and people will be going slowly insane as the disrepair of the world around them wears on their psyche. For added depth, I'll be letting the main survivor group be entirely run by non-admins, that way the leader(s) have no clue how events are going to unfold and it allows for mistakes to be made. Makes for better roleplay that way :v
I also had an idea of what I could do to keep players occupied since standing around in your survivor camp gets boring if there's really not much to do. A real survival camp in a zombie apocalypse would require constant maintenance, so I could set it up so there would always be a barricade to repair, or a pipe leaking, or even sometimes a fire possibly. If the survivors neglect the issues that pop up, their camp safety number would go down, and if it gets too low, then stuff like barricades breaking or generators going out could happen.
edit: Oh yeah and the setting for the server will be the scifi-ish late 70s. Expect stuff to be wacky right off the bat.
