🧟 UndeadPandemic

Transform your Minecraft world into a full-blown post-apocalyptic survival experience

Fight the infection. Purify your water. Survive the Blood Moon.

Docs Premium

Paper • Spigot • Purpur  |  Built for 1.21  |  Latest: 3.2.1

UndeadPandemic Features

☣️ Unleash the Apocalypse

UndeadPandemic overhauls survival gameplay, plunging players into a relentless world where every decision matters. Water, food, and the infected are all vectors for the plague. Adapt fast, scavenge smarter, and stay one step ahead of the infection… or become part of it.

This isn't just survival. It's survival reimagined.

💥 Features

  • 🧪 Zombie Infection System — Water, food, and zombies are all vectors. Stay clean, or become one of them. Configure symptom onset, infection duration, mutation severity, and transmission.
  • 🩸 Zombie Guts Camouflage — Smear yourself in zombie remains to become invisible to the horde… until it rains and washes it away.
  • 🌧️ Environmental Reactions — Rain extinguishes campfires, strips camouflage, and fills cauldrons. Survival means adaptation.
  • 🌕 Blood Moon Events (Premium) — Night events that make zombies faster, stronger, and relentless. Greater loot… if you survive.
  • 🥩 Infected Livestock — Even your animals may turn against you. Rotten flesh is only the beginning.
  • 💧 Thirst & Dehydration — Hunger isn't your only enemy. Dehydration weakens players until survival slips away.
  • ⛺ Secure Camps — Build from a humble tent and firelight up to a fortified stronghold with locked doors and defences.
  • 🏆 Rewards & Integration — Earn rewards for kills, hook into Vault economy, track stats via PlaceholderAPI, and protect regions with WorldGuard.

# UndeadPandemic v3.2.2 & v3.2.3

Two releases rolled into one update post — covering build 427 and build 428.

## v3.2.3 (Build 428) — September 21, 2026

### Bug Fixes
  • Fixed some items not working
  • Fixed barbed wire
  • Premium players' zombie virus no longer progresses faster than free — a duplicate symptom path that was double-advancing infection has been removed

### Changes
  • Colds now have real symptoms on **all** servers, not just premium (fever, sneezing, hunger, and mild aches)
  • Colds are now cured by warming up, consistent with how they're caught
  • Zombie virus now adds nausea at high infection levels (>75)
  • New config toggle: illnesses.cold.symptoms-enabled (default true) in health.yml
  • Several premium features have moved to free.** Most of the plugin is now playable for free — Zombie Guts is now free, with only Cauldron and Campfire functions remaining premium

### A note for Premium users
If you've already purchased Premium, you haven't been forgotten. Moving features to free is about making the core plugin better for everyone — but Premium is getting its own dedicated update next, focused entirely on new premium content. Planned: decomposing zombies, playable zombies on player death, expanded config options, health system enhancements, and more.


## v3.2.2 (Build 427) — August 20, 2026

### New Features
  • Added a resource pack manager with config options to auto-apply to joining players and other personalisation settings

### Bug Fixes
  • Fixed a minor getter name issue
  • Fixed key-name mismatches when fetching messages
  • Various other small, unnoteworthy fixes

### Changes
  • Premium licence check on server load is now asynchronous — faster startup if the API is slow or unreachable
  • Split the large config.yml into 8 smaller, system-specific config files, now living under /plugins/UndeadPandemic/config/
  • Codebase is now routinely obfuscated (licensing/proprietary reasons, not security)

  • Fixed duplicate bossbar bug for thirst.
  • Fixed barbed wire registration bug issue.
  • Fixed zombie guts bugs.
  • Fixed barbed wire.
  • Fixed tprch bugs and changed torch to be a toggle on/off.
  • Improved headshot reliability.
  • Fixed headshot sensitivity and difficulty.
  • Fixed bugs with campfires and cauldrons.
  • Added suppress-named-mob-death-log config option to suppress named mob logging and keep the config clean. Set to true by default.
  • Refactored entire plugin to increase performance.

This version will be updated repeatedly until the next release-candidate is ready so check back often for updates.

[2.7.8-222] v2.7.8-222 by GamerMedic on Oct 15, 2026
Download
== New Features & Bug Fixes ==

__*config.yml update recommended, but not required.*__

Changes include:

  • Added infected water system.
  • Updated wiki with relevant information.
  • Added infected animals system.
  • Surf & Turf included.
  • Known Issue: If you fish up an infected fish the fishing rod will stick. Right click until it unsticks. This bug is being fixed.
  • The undeadpandemic.immune permission has been set to false by default. This means that admins can be infected unless they are specifically given this permission.
  • Added use_whitelist option to config.yml. Setting this option to true will turn disable_in_worlds into a whitelist instead of blacklist.
  • EntityDamageByEntityEvent error fixed
  • NullPointerException error fixed
  • == Bug Fixes & Updates ==**

  • config.yml update recommended, but not required.**

Changes to include:
  • Removed weapons system. You can no longer use native guns and ammo.
  • The weapons system was removed because there are much better weapons systems on the market and it's far better to utilise these systems. Killing zombies will still drop rewards.
  • Future updates will allow loud weapons to attract zombies again. In the meantime, these config.yml settings will not do anything.
  • Updated how head shot is calculated when a zombie is killed.
  • Fixed NullPointerException error on PlayQuitEvent.
  • Fixed bug where the first aid kits do not contain items.
