Zombie Apocalypse Addon Wiki

Zombie Apocalypse Addon turns Minecraft into a configurable zombie survival world. It can add daytime zombie pressure, hordes, blood moons, long-term difficulty growth, optional base attacks, and support for modded zombies.

You can use the recommended preset and never touch the advanced settings.

Current Builds

Loader Minecraft Mod version File name
NeoForge 1.21.1 2.2.30 zombieapocalypseaddon-2.2.30.jar
NeoForge 1.20.1 1.5.24 zombieapocalypseaddon-neoforge-1.20.1-1.5.24.jar
Forge 1.20.1 1.5.24 zombieapocalypseaddon-forge-1.20.1-1.5.24.jar

Do not install more than one loader version.

Install

  1. Back up the world.
  2. Put the correct jar in the server mods folder.
  3. Start the server.
  4. Join as an operator.
  5. Run /za.

Multiplayer players do not need the mod on their clients. Singleplayer users install it on the client because singleplayer runs a local server.

Fast Setup

Run one preset:

/za preset casual
/za preset standard
/za preset hardcore
Preset Use it when...
Casual You want fewer zombies, a day-10 daylight grace period, no baby zombies, and torch-protected bases.
Standard You want the recommended default balance.
Hardcore You want faster waves, larger events, and quicker difficulty growth.

Presets change the main spawning, event, and basic scaling settings. They never enable block breaking, block placing, or towering.

Check the result with:

/za status

Commands to Remember

/za
/za help
/zdayspawn
/zhorde
/zscaling
/zcompat
  • /za is the main dashboard.
  • /za help lists short help topics. /zhelp is a shorter alias.
  • Bare feature commands show status.
  • /za help start explains first setup again.
  • /za help all lists every command family.

If the World Is Too Hard

Use the Casual preset first:

/za preset casual

Or change only one setting:

/zdayspawn chance 0.25
/zdayspawn interval 180
/zdayspawn daylightstart 10
/zdayspawn babychance 0
/zdayspawn maxlight 7

0.25 means 25%. 180 ticks means 9 seconds. A max light of 7 lets brighter bases block custom waves.

Optional Base Pressure

These features are separate and disabled by default:

/zblockbreak
/zblockplace
/ztower

Each bare command shows its status. Use on, off, startday <day>, or dayone for simple control. Read the command page before enabling block breaking or placing on an important world.

Config

The config file is:

config/zombieapocalypseaddon-common.toml

Stop the server before editing it. The file begins with a START HERE section.

Normal servers should focus on:

  • [dayspawning]
  • [variants]
  • [horde]
  • [bloodmoon]
  • [scaling]

Leave compatibility and advanced attributes at their defaults unless you have a specific reason to change them.

Safe Removal

Before removing the mod, run:

/zcleanup uninstall

Then stop the server and remove the jar. See Safe Uninstall for details.

Getting Help

  1. Check Troubleshooting for the common spawning, difficulty, protection, compatibility, and performance fixes.
  2. Run /za status and the bare command for the affected system.
  3. Use the matching GitHub issue form if the problem remains.

Include the exact Minecraft version, loader, mod version, config, complete mod list, and logs/latest.log. Remove server addresses, tokens, and private player information before posting.
