Zombie Apocalypse Server Hosting

We recommend 6 GB. That figure comes from the 106 mods in the pack at medium weight plus a group of around six. Zombie-heavy nights are the real stress test, because every spawned mob runs its own AI. If your group explores far apart or grows, add a gigabyte or two and run spark during an attack to confirm.

There is no slot cap on our side, because plans are sized by RAM. The 6 GB recommendation is built around a squad of roughly six, which matches how the pack plays. Bigger groups work too, but players spread across the map multiply loaded chunks and zombie spawns, so raise memory as the group grows.

Make a backup in the panel, then switch to the new build in the Modpacks tab. Build 1.1 is the latest right now. Check the changelog for weapon or mob mods that were removed, because their items vanish from chests and inventories. Every player must move their client to the matching build before reconnecting.

Yes. Upload extra Fabric mods for 1.20.1 to the mods folder through the file manager or SFTP, and add any mod that also needs a client copy to every player's install. Server-side tools like Chunky need nothing on the client. Removing a gun or mob mod is riskier: anything it placed in the world disappears, so back up before trimming.

A typical adventure pack adds dungeons and bosses but leaves the overworld much as it was. Zombie Apocalypse changes the threat itself: the undead are the constant pressure and guns are the main tool against them. It is also tagged challenging, so expect fewer safe nights and more time spent defending what you built.

Yes. Most of the 106 mods add content the client has to render, including the weapons and mobs, so every player needs Zombie Apocalypse on build 1.1 with Fabric for 1.20.1. Any launcher that imports Modrinth packs can install it directly. A mismatched build usually fails at login with a list of missing or different mods.
