I found a modded Minecraft server where you and a few other players try to survive 100 days in a zombie apocalypse.
It is meant to be played together and the whole idea is surviving as long as you can. There are join instructions in their Discord.
They also say you can try the modpack by yourself first and it is called Protocol Zero Modern Zombie Apocalypse.
