Ultra Zombie Apocalypse

Quickstart

1. Install the .mcaddon and enable both the Behavior Pack and Resource Pack on your world.
2. Set difficulty to Easy, Normal, or Hard — the horde controller is inactive on Peaceful.
3. Survive to nightfall. Waves of zombie variants will begin spawning automatically around you within seconds of night starting.
4. Watch your action bar for the live HUD: Night number, nearby horde count, and seconds until next wave.
5. Use daylight hours to build or reinforce defenses — the HUD will show your next-night number and a "Respite" indicator while the sun is up.
6. To test any variant immediately, find its spawn egg in the Creative inventory (search "Zombie Spawn Egg") and use it anywhere.

Overview

Ultra Zombie Apocalypse transforms every night into an escalating survival siege. A built-in horde controller tracks the current night number, spawns waves of custom zombie variants near each player, and grows those waves larger and more dangerous with every passing night. Early nights bring familiar foes; later nights unlock heavy elite variants that can shrug off most damage and hit back hard. The cycle never fully resets — each night is harder than the last.

What It Adds

Thirteen Zombie Variants

All variants carry unique apocalypse-themed textures and have their own spawn eggs available in Creative mode.

Horde Controller HUD

A live action-bar display is always visible at night:

Ultra Zombie Apocalypse | Night [#] | Horde nearby [count] | Next wave [seconds]s

During the day the bar shows respite status and the upcoming night number.

How To Use

Surviving Nights

Waves spawn in a ring roughly 18–34 blocks from each player. The horde controller respects a per-player cap, so the number of active zombies near you is always tracked. When the cap is not yet reached, a new wave spawns on a countdown timer. Wave size grows each night: early nights spawn small groups, while later nights push many zombies at once.

Defense Building

Zombies can and will break through common building materials. Avoid relying on:

• Planks and wood-type blocks
• Dirt and grass blocks
• Sand and red sand
• Sandstone and red sandstone
• Cobblestone (and stone variants)

Use harder materials — deepslate, stone bricks, obsidian, and similar blocks — for walls and choke points that can hold against the horde.

Zombies can also break doors, so reinforcing entryways is critical on higher nights.

Using Spawn Eggs

Every variant has a dedicated spawn egg obtainable from the Creative inventory. Use them to:

• Test how a specific variant behaves before facing it in a horde.
• Set up training arenas or challenge rooms.
• Experiment with defenses and weapon effectiveness.

Abilities And Mechanics

Block Breaking

Approximately every 8th attack, a zombie will attempt to destroy a breakable defense block directly adjacent to it. This means even well-placed walls can be torn down if a horde hammers them long enough. Rotate your defenses and have fallback positions ready.

Status Effects On Hit

Several variants apply debuffs when they strike you:

• Wither Zombie — Wither effect, draining health over time.
• Creepy Zombie — Approaches invisibly; no visual warning before contact.
• Crawling Zombie — Despite its Slowness, its Resistance makes it difficult to kill quickly.
• Tank / Mutant / Iron Golem Zombie — Regeneration means sustained DPS is required; burst damage is less effective.

Night Unlock System

Rarer, more dangerous variants are locked behind night thresholds. You will not see a Tank Zombie until Night 5, a Mutant Zombie until Night 6, or an Iron Golem Zombie until Night 7. Surviving early nights is therefore a genuine warm-up, not just a delay.

Loot

All variants drop Rotten Flesh (0–2, improved by Looting). When killed by a player or their pets, each variant has a small chance (~2.5%, slightly improved by Looting) to also drop one of:

• Iron Ingot
• Carrot
• Potato

Progression And Strategy

Nights 1–2 (Normal / Baby / Running / Super / Military / Skeleton) Focus on establishing a sturdy base perimeter using blocks that zombies cannot break. Learn the wave timer from the HUD and use the countdown to position yourself before each wave arrives.

Nights 3–4 (+ Wither / Creepy / Crawling / Mutiny) Invisible Creepy Zombies make open-ground fighting dangerous. Funnel enemies through lit, narrow choke points so you can see and track them. Carry milk buckets to counter Wither.

Nights 5–6 (+ Tank / Mutant) Tank and Mutant Zombies regenerate health, making attrition fights losing battles. Use fire, strong enchanted weapons, and focused single-target DPS to burn them down before they heal. Retreat is better than standing and fighting a regenerating Tank in a crowd.

Night 7+ (+ Iron Golem Zombie) Iron Golem Zombies are the heaviest enemies in the mod — 150 HP, extreme Resistance, and high Strength, offset only by Slowness. Use their slow movement against them: kite them around obstacles, maintain distance, and avoid letting them corner you. Consider dedicating ranged attack options (bows, crossbows) specifically for these enemies.

General Tips

• The horde cap is per-player, so in multiplayer each player draws their own horde — coordinate positioning to avoid being overwhelmed simultaneously.
• Daylight is your resource. Use every sunrise to repair walls, restock supplies, and advance your gear before the next night's larger wave hits.
• Looting-enchanted weapons increase your rare drop chances and help you stockpile iron from the horde over time.
