Blood Moon Cities

Quickstart

1. Load a world with the mod installed. The action bar immediately shows your current day, variant number, and evolution percentage.
2. Run this command to find the nearest Blood Moon City biome: /locate biome com_blood_moon_cities_5okupysj:blood_moon_city
3. Travel to the city and loot the ruined structures for iron ingots, food, and custom gear drops.
4. Craft your first weapons and armor at a crafting table as soon as you have iron ingots and leather:
   • Survivor Machete — your primary melee weapon
   • Riot Helmet and Riot Chestplate — core protection pieces
5. On Day 10, a one-time military supply drop delivers a Survivor Machete, Riot Helmet, and Riot Chestplate directly to you — but 8 City Zombies spawn alongside it, so be ready to fight.
6. Survive every 7th day: those are Blood Moon nights with significantly increased zombie pressure around all players.

Overview

Blood Moon Cities transforms your Minecraft world into a zombie apocalypse. A new overworld biome — the Blood Moon City — generates crumbling urban landscapes inspired by real American cities: Atlanta, Las Vegas, New Jersey, New York City, Los Angeles, and Indianapolis. The streets are paved with Cracked Asphalt and overgrown with Undead Weeds, and the ruins hold valuable loot.

Beyond the biome, the entire world changes. Vanilla mobs convert into zombies over time, a persistent HUD tracks your progress through a 1,200-day variant cycle, and escalating threats — blood moons, nuclear strains, and evolving zombie variants — pressure you harder with every passing day.

How To Use

Finding the Biome

Use the command /locate biome com_blood_moon_cities_5okupysj:blood_moon_city to get coordinates for the nearest Blood Moon City. Head there to loot ruins and farm City Zombies for drops.

Reading the HUD

Your action bar always shows:

• Day — current world day
• Variant X/1200 — which zombie variant cycle you are on (resets after 1,200 days)
• Evolution % — current chance that a vanilla mob converts into a zombie each cycle (67% on Days 1–99, 90% from Day 100 onward)
• BLOOD MOON — displayed in red on every 7th day
• NUCLEAR STRAINS — displayed from Day 40 onward

Zombie Conversion

Roughly every 30 seconds, all vanilla mobs across the Overworld, Nether, and The End have a chance to be replaced by City Zombies (or Nuclear Zombies from Day 40). You cannot stop this — gear up fast.

Crafting And Obtaining

All gear is crafted at a crafting table using iron ingots and leather. Recipes unlock when you have iron ingots in your inventory.

Survivor Machete

Riot Helmet

Riot Chestplate

Riot Leggings

Riot Boots

Loot Drops

Day 10 Military Supply Drop

On Day 10 only, every player automatically receives a Survivor Machete, Riot Helmet, and Riot Chestplate dropped at their feet. Eight City Zombies spawn at the same location — treat it as a dangerous but rewarding event.

Abilities And Mechanics

Blood Moon (Every 7th Day)

On days divisible by 7, extra City Zombies (and Nuclear Zombies from Day 40 onward) spawn in a radius around every player. Before Day 100, up to 3 additional zombies appear per player per cycle. From Day 100 onward, up to 5 spawn per cycle.

Zombie Evolution

Every ~30 seconds the mod scans all loaded mobs and replaces eligible vanilla mobs with zombies:

• Days 1–99: 67% conversion chance per mob
• Day 100+: 90% conversion chance per mob

From Day 40 onward, each converted mob has a 35% chance of becoming a Nuclear Zombie instead of a City Zombie.

Nuclear Zombie Threat

Nuclear Zombies begin appearing from Day 40. They share the same base stats as City Zombies but have a unique appearance and drop Riot Leggings on death, making them high-value targets worth hunting carefully.

Variant Counter

The HUD variant number cycles from 1 to 1,200 and then resets. Each zombie spawned by the conversion system is tagged with the current variant number, tracking how far the apocalypse has evolved.

Progression And Strategy

Tips:

• Complete your full Riot armor set before Day 40 when Nuclear Zombies arrive — Riot Leggings can only be crafted or looted from Nuclear Zombies.
• Stay mobile on Blood Moon nights; zombies spawn within ~12 blocks of you in all directions.
• City Zombies can break doors, so wood-door bases offer no safety — use iron doors or build defensible positions early.
• The conversion system affects the Nether and The End too — do not assume those dimensions are safe refuges.
