Description
Blood Moon Britain overhauls survival into a full UK zombie apocalypse centered on a real custom overworld biome—the Ruined British City—which replaces plains in worldgen, uses ruined-asphalt and rubble-soil surface materials, includes biometags so you can find it with /locate biome, and spawns ruined UK shopfronts and abandoned military checkpoints as city landmarks. Every hostile mob is converted into the Evolved British Zombie and nights bring blood moons with an on-screen HUD/action bar showing day, evolution percentage, and blood moon state; zombies scale and mutate over time (12% evolution from day 2–30, mutation abilities from day 67, 120% spikes around days 99–110, and massive 999% evolution on and after day 500), producing tougher, special-ability undead. Loot is military-grade with a scripted Military Rifle and a Military Body Armor item included, and on first spawn players are assigned to separate UK cities and teleported to fully stocked safe houses with starter supplies, weapons, and armor so you can dive straight into the apocalypse.

Overview
Blood Moon Britain transforms survival Minecraft into a UK zombie apocalypse. The overworld grows a custom Ruined British City biome in place of plains. Every hostile mob you encounter has been replaced by the Evolved British Zombie — an undead enemy that grows stronger, faster, and more dangerous with every passing day. Nights are blood moons, and the longer your world runs, the more mutated and lethal the horde becomes.

How To Use
The HUD
Every few seconds your action bar updates with three pieces of information:
- Day — the current in-game day number.
- Zombie evolution % — how powerful the zombies currently are.
- BLOOD MOON — shown in red during nighttime hours when the horde is at its most dangerous.
The Military Rifle
Hold the Military Rifle and use it (right-click / tap the use button) to fire. It targets the nearest non-player entity within 28 blocks and deals 12 damage instantly. An explosion sound plays on each shot. The rifle has no ammo cost — it fires on use alone.
Evolved British Zombies
These are the only hostile mob you will encounter. They spawn in groups of 2–4 in low-light conditions on the surface and underground, exclusively in the Ruined British City biome. They can climb, break doors, and pick up dropped weapons and armor. Killing one drops 0–2 rotten flesh, and there is a small chance of an iron ingot, carrot, or potato if you land the killing blow.
Crafting And Obtaining
Military Rifle


The Military Body Armor is given to you in your starting safe house. It is not craftable — protect it carefully.
Ruined Asphalt and Rubble Soil drop themselves when mined and can be collected from the Ruined British City biome.
Abilities And Mechanics
Zombie Evolution System
The evolution percentage displayed on your HUD determines how powerful every nearby zombie is. Buffs are applied continuously.
| Day Range | Evolution % | Active Buffs |
|---|---|---|
| Day 1 | 0% | None |
| Days 2–30 | 12% × (day − 1), up to ~348% | Strength, Speed |
| Days 31–66 | 0% (plateau resets) | Strength, Speed |
| Days 67–98 | 120% | Strength, Speed, Resistance |
| Days 99–110 | 120% (spike phase) | Strength, Speed, Resistance |
| Days 111–499 | 120% | Strength, Speed, Resistance |
| Day 500+ | 999% | Strength, Speed, Resistance, Health Boost |
During nighttime (blood moon), all zombies also gain Regeneration, making them extremely difficult to whittle down. The higher the evolution %, the stronger the Strength and Speed buffs applied.
Baby Zombies
Evolved British Zombies can spawn as baby variants — smaller and faster than adults, worth more XP on kill.
Zombie Jockeys
Baby Evolved British Zombies can mount adult Evolved British Zombies, creating jockey pairs that move with increased speed.
Mob Replacement
Any vanilla hostile mob (skeleton, spider, creeper, enderman, witch, pillager, or vindicator) that appears near a player is immediately replaced by an Evolved British Zombie, keeping the horde themed at all times.
Progression And Strategy
Early game (Days 1–30): Zombies are manageable but ramp up quickly. Use your starting rifle and sword to clear the immediate area around your safe house. Stock up on food and arrows. Mine Ruined Asphalt and Rubble Soil for building materials.
Mid game (Days 31–66): Evolution briefly plateaus, giving you a window to explore, find loot in ruined shopfronts, and fortify your position. The iron-bar safe house walls are a good template — build out from there.
Days 67+: Zombies gain Resistance. Sustained combat becomes significantly harder. Prioritise the Military Rifle for ranged damage. Avoid prolonged night fights — blood moon Regeneration means zombies can outhealing your sword damage.
Days 99–110 (spike phase): A particularly dangerous stretch. Stay indoors at night.
Day 500+: The 999% evolution state gives every zombie near-maximum Strength, Speed, and a massive Health Boost. This is effectively end-game difficulty. Prepare powerful weapons, full armor, and a well-defended base before this threshold arrives.
Finding the biome: If you leave your starting city, use /locate biome com_blood_moon_britain_ai2otl3j:ruined_british_city to navigate back to the apocalypse zone where Evolved British Zombies naturally spawn.
