How to Host a ZombieCraft: Zombie Apocalypse Server
ZombieCraft: Zombie Apocalypse puts your group across sprawling cities with guns and zombies that evolve the longer the apocalypse runs — a different take on zombie survival from the already-covered ZOMBIEMANIA pack, which leans on gunshot and blood-scent AI in a wintry setting instead. Getting a Forge 1.20.1 server like this running smoothly comes down to a few steps most people skip.
Start the server with at least 8 GB of RAM allocated. That's the recommended floor for this pack's Forge mod list on 1.20.1 — big-city map generation and the evolving zombie AI both lean on memory, and starting lower just means you find out the hard way mid-session.
Import the modpack directly from its original file instead of rebuilding it from a client-side export. Hand-copied client mod lists drift from the server-required set over time, and this pack's custom weapon and zombie-evolution mods need to match exactly between client and server.
Watch the console through the first boot and let it finish loading completely before you consider the server ready. This pack generates sprawling city structures and initializes its zombie evolution tracking on startup — a log full of errors here, or a boot that never settles, means something needs fixing before anyone logs in.
Only invite players once that first boot has completed cleanly. Letting people in during an unstable startup is how city chunks end up half-generated and zombie spawns end up broken for the rest of the world's life.
Take a backup before importing an existing world, updating the Forge loader, or changing gun or zombie-evolution configs. If a change goes wrong, a fresh apocalypse with zombies back at stage one is not what anyone wants to explain to the rest of the group.

CoalHost is built around modpack hosting, which makes ZombieCraft: Zombie Apocalypse much less annoying to launch correctly.
