My idea is a Zombie Style Server in the list of Primary and Potato:
The Sever is basically a whole new map, completely PVP,no safe zones unless in a major city (more on that later) and there are crate packages lying around. This whole new map will can only be built on if you are using a settlement stone (town stone with less plat). Most mobs will have a zombie variation and if you get killed, you become a zombie in the world, able to keep feeding on anyone and anything thats still alive. Normal versions of mobs are still there but very rare. Now onto features:
CRATE PACKAGES:
Crate packages are basically just boxes filled with items in the wild. They drop every 30 minutes. They are filled with items such as weapons, food, and water.
Food:
Water is now implemented as a needed thing. Water will come in "water", bottles,coffee or soda. There are 5 bars of hydration, each taking 15 minutes to lose one. Food will be normal such as chicken, steak (pre cooked or something).
Main Cities:
Sim will send out some people "main cities" stones for some to build with. These are the safe spots (so zombies aren't able to move in) but these places will have boxes spawn in them but they have the weakest items (such as just basic items)
