Empire Of The Blood Moon

Quickstart

1. Install the .mcaddon and create a new world with both the Behavior Pack and Resource Pack active.
2. Use /locate biome com_empire_of_the_blood_moon_6mfn7vi3:nyc_biome to find the NYC Apocalypse biome, then teleport there.
3. Explore the cracked streets, ruined brownstones, elevated train stations, and subway entrances. Enemies spawn densely — be ready to fight immediately.
4. Watch the action bar at the bottom of your screen. It shows your current Apocalypse Day, active mutation pool, nearby horde count, next wave timer, and threat tier.
5. Survive until nightfall on Day 5 — that's when horde waves begin. Every seventh night triggers a Blood Moon: the sky locks to night, thunder rolls, and larger waves descend.

Overview

Empire Of The Blood Moon transforms your overworld into a post-apocalyptic survival gauntlet. Two fully custom biomes — a ruined NYC cityscape and the twisted Bloodmoon Wastes — sprawl across the world, each packed with unique enemies, structures, and escalating danger. A living mutation engine gives every zombie a unique name and powers that grow stronger with each passing in-game day, while a horde controller sends waves of enemies at you every night. Survive long enough and the world itself becomes unrecognisable.

What It Adds

Biomes

NYC Apocalypse is a dense urban ruin featuring:

• Ruined brownstone buildings
• Elevated train stations with interior loot
• Subway entrances leading underground
• Taxi stands and cracked streets

Bloodmoon Wastes is a corrupted wasteland that is the home territory of the Bloodrot Zombie — the primary enemy of the night-horde system.

Entities

All zombie types have spawn eggs available in Creative mode, and burn in daylight like standard zombies. If submerged in water long enough, they will convert into Drowned.

How To Use

Navigating to the Biomes

Use /locate biome to find either custom biome, then teleport to the coordinates it returns. The biomes generate as part of the standard overworld and are found by simply exploring, but the locate command saves time.

Reading the HUD

Every player sees a persistent action bar message while the mod is active:

Apocalypse Day 3 | Tier: street rot | Mutations 482, 91034, ... | Horde 0 | Next wave 42s

• Apocalypse Day — the current in-game day count.
• BLOOD MOON — appears in the bar on every seventh day.
• Tier — the current escalation tier name (see Progression below).
• Mutations — five active variant IDs for the day. Each zombie spawned today pulls from this pool.
• Horde — how many Bloodrot Zombies are within ~48 blocks of you right now.
• Next wave — seconds until the next horde wave spawns (only active at night from Day 5).

Horde Waves

Starting on Night 5, a wave of Bloodrot Zombies spawns around each player every 45 seconds while it is nighttime. Waves spawn in a ring roughly 22–40 blocks away from you so they close in quickly. The number of zombies per wave scales with the day count:

• Normal nights: 4 + (day ÷ 10) zombies, capped at 18.
• Blood Moon nights: 8 + (day ÷ 10) zombies, capped at 18 — plus thunder weather and a locked night sky.

Blood Moon

Every seventh Apocalypse Day, the night becomes a Blood Moon. The time is forced to night and a thunderstorm begins. Horde waves are larger, and all zombies carry the day's maximum mutations. Survive until morning to break the event.

Abilities And Mechanics

Procedural Mutation System

Every zombie that spawns — including vanilla zombies — is automatically mutated by the day's active mutation pool. Each zombie receives:

• A unique name tag combining a prefix and trait (e.g. Blood Brute #4821, Tunnel Feral #10032).
• Strength and Speed effects that scale with the day and variant number.
• From Day 30 onward, Resistance is added as well.

The mutation pool is deterministic per day — all five variant IDs are the same for every zombie that spawns on a given day, refreshing at dawn. With up to 15,000,000 possible variant numbers, no two days feel identical.

Zombie Behavior

All zombie types share these traits:

• Can break doors and navigate around obstacles.
• Can climb surfaces and swim.
• Will pick up and equip weapons they find on the ground.
• Baby variants move faster than adults.

Loot On Death

Killing custom zombies drops loot at their location:

The rare drop chance is low (~2.5%) but increases slightly with Looting enchantments.

Progression And Strategy

The threat tier displayed on your HUD tells you what to expect as the days climb:

Early game (Days 1–4): Explore the NYC biome safely during the day. Loot stations and tunnels, find NYC Survivors, and build a defensible base before night horde waves begin.

Mid game (Days 5–29): Horde waves start. Stay mobile at night, use chokepoints, and watch the "Next wave" timer so you're never caught in the open when a wave drops.

Late game (Days 30+): Zombies gain Resistance on top of Strength and Speed. Bloodrot wave sizes grow. Prioritise high-damage weapons and armour. Every seventh night will be a Blood Moon — these are the hardest nights and require preparation.

Blood Moon survival tips:

• Stock up on food and healing before dusk on days 6, 13, 20, etc.
• Avoid open ground — waves spawn in a ring around you.
• Engage the horde at range if possible; Bloodrot Zombies close distance fast.
• You cannot skip past the Blood Moon night with /time set day while the event is active.
