Doomsday Zombie Evolution

Quickstart

1. Add the .mcaddon to Minecraft Bedrock and apply both the Behavior Pack and Resource Pack to your world.
2. Load in and start playing — no commands or setup are needed.
3. Watch your action bar: it shows the current Doomsday Day and the active threat phase.
4. Check the sidebar scoreboard (Doomsday_Day) to track progression.
5. Survive as long as you can — every in-game day the zombies get stronger, and familiar mobs around you will begin converting into mutant variants.

Overview

Doomsday Zombie Evolution transforms your entire world into a zombie apocalypse that escalates automatically over time. From the moment the world loads, a background system scans for mobs nearby and converts them into increasingly powerful mutant zombies. Every Minecraft day that passes, every zombie on the map grows stronger — and once key day thresholds are crossed, special named, geared zombie variants emerge. There is no end state short of day 1000, when the world is flooded with MAX DOOMSDAY MUTANTS.

What It Adds

Mob Conversion

Almost every mob — including normally unkillable bosses like the Warden, Wither, Ender Dragon, and Elder Guardian — can be converted into a zombie variant. Converted mobs become one of three types:

Existing zombie-family mobs (zombies, husks, drowned, zombified piglins, etc.) are left as-is for conversion into evolved variants.

Live HUD

Every second, your action bar displays:

🔴 Doomsday Day [X] | [Current Phase] | Zombies evolve daily

The sidebar scoreboard tracks the same day counter under the label Doomsday_Day.

Abilities And Mechanics

Daily Zombie Evolution

All zombies in the world receive escalating potion effects that grow stronger with each passing Minecraft day:

Block Breaking

Zombies actively break blocks around them. Bedrock and obsidian are the only blocks fully protected. Every other block — including most building materials — can be destroyed by the horde as the days go on.

Named Variant Milestones

When the world reaches certain day thresholds, zombies transform into themed, named variants with matching gear:

Each zombie receives the highest milestone name and gear appropriate to the current day when it is evolved. A zombie will not be re-named once it already carries a given milestone tag.

Special Mutant Types

• Mutant Baby Zombie — Spawned from baby mobs or at random; small but carries standard daily evolution buffs.
• Mutant Iron Golem Zombie — Spawned when an Iron Golem is converted; permanently carries Resistance VIII and Strength XII on top of daily evolution scaling, making it extraordinarily durable.

Progression And Strategy

Early game (Days 1–17): Zombies are relatively standard but are already stronger than vanilla. Use this window to fortify with obsidian — it is one of only two blocks guaranteed to survive the apocalypse.

Mid game (Days 18–49): Named variants begin appearing with weapons and armor. Trump and Obama Zombies arrive first with light gear; Chinese and Russian Military Zombies follow with iron and diamond equipment. Combat becomes noticeably more dangerous.

Late game (Days 50–999): Nuclear Mutant Goatman Zombies appear wielding netherite axes. Resistance and Speed buffs are significant. Block breaking becomes a major structural threat.

Endgame (Day 1000+): MAX DOOMSDAY MUTANT ZOMBIEs dominate the world. They wield netherite swords, wear netherite armor, regenerate health, and can leap with Jump Boost IV. Survival is the ultimate challenge.

Key survival tips:

• Build shelters from obsidian early — it is the only common building block zombies cannot destroy.
• Bedrock is also safe, but you cannot place it in survival.
• Do not let Iron Golems be converted — Mutant Iron Golem Zombies have near-permanent extreme resistances.
• Monitor the sidebar scoreboard and action bar to anticipate upcoming variant milestones and prepare accordingly.
• Boss mobs (Warden, Wither, Ender Dragon) will be converted if they are within range — do not count on them surviving as distractions for long.
