Description
Worldfall: Zombie Siege remakes the overworld into a realistic urban apocalypse centered on a custom Worldfall Warzone biome (com_worldfall_zombie_siege_kehg25c5:worldfall_warzone) — an overworld replacement with Warzone Asphalt surfaces, Rebar Weeds foliage, ruined city rubble structures, biome tags and client colors so you can find it with /locate biome. Players begin in one of seven stocked safe houses (Berlin, Moscow, Paris, Rome, London, Beijing, or Taipei) with starter military supplies and Military Supply Crates, then scavenge the warzone for military-grade loot, weapons, armor and custom zombie drops. All hostile monsters are converted at runtime into the Worldfall Evolved Zombie (with its spawn egg and retextured model), and a blood-moon system plus an action-bar HUD track day, blood moon, evolution percent and mutation state as zombies evolve 12% per day from day 2–30, gain mutation abilities on and after day 67, spike around days 99–110, and reach extreme evolution on and after day 500.

Worldfall: Zombie Siege
Quickstart
- Install the
.mcaddonand create a new world — the mod applies at world scope. - The moment you first spawn, you are teleported into one of seven city safe houses (Berlin, Moscow, Paris, Rome, London, Beijing, or Taipei) and given a starter kit: iron sword, bow, 64 arrows, full iron armor, and 3 Military Supply Crates.
- Use a Military Supply Crate from your hotbar to immediately open it and receive 16 cooked beef, 32 arrows, 2 splash potions, and 8 iron ingots — essential early supplies.
- Step outside your safe house and explore the Worldfall Warzone biome. Watch the action bar at the bottom of your screen — it tells you the current day, blood moon status, and zombie evolution level.
- Kill Worldfall Evolved Zombies for loot, and survive as long as you can as they grow stronger each day.
Overview
Worldfall: Zombie Siege transforms the overworld into a post-apocalyptic urban warzone. The familiar Minecraft landscape is replaced by a custom Worldfall Warzone biome — cracked asphalt streets, rusted rebar weeds, and ruined city rubble as far as you can see. Every hostile mob in the world is replaced by the Worldfall Evolved Zombie, a custom retextured enemy that grows more dangerous with every passing day. A persistent HUD keeps you informed of the threat level at all times. Survival is the only goal.

Safe Houses
Seven pre-built stone shelters are constructed at world start, one per player (cycling through the list for additional players):

Each safe house is a hollow stone room with a Warzone Asphalt floor, an iron door entrance, and a chest inside.
How To Use
Action Bar HUD
A persistent display appears at the bottom of your screen at all times:
Worldfall Day [X] | Blood Moon: ACTIVE / Dormant | Zombie Evolution [X]% [MUTATION]
- Day — the current world day count.
- Blood Moon — active from day 2 onward.
- Zombie Evolution % — how powerful the zombies currently are (see Progression below).
- MUTATION — appears on day 67 and beyond, indicating zombies have gained mutation abilities.
Military Supply Crate
Hold the crate in your hand and use it (tap/right-click) to open it. You cannot place it — activating it immediately grants:
- 16 Cooked Beef
- 32 Arrows
- 2 Splash Potions
- 8 Iron Ingots
Locating the Warzone Biome
Use the command /locate biome com_worldfall_zombie_siege_kehg25c5:worldfall_warzone to find the nearest Worldfall Warzone area if needed.
Crafting And Obtaining
There are no crafting recipes in this mod. All items are obtained through gameplay:
- Military Supply Crate — given at spawn (×3) and dropped by Worldfall Evolved Zombies (0–2 per kill, with looting bonus).
- Warzone Asphalt — mine it from the ground in the warzone.
- Rebar Weeds — break them anywhere in the warzone.
- Starter kit (iron armor, sword, bow, arrows) — given automatically at first spawn.
Abilities And Mechanics
Zombie Evolution System
Every Worldfall Evolved Zombie near a player is continuously updated with strength and speed effects scaled to the current day. The evolution percent shown on the HUD determines their power tier:
| Day Range | Evolution % | Effect Amplifier | Special Abilities |
|---|---|---|---|
| Day 1 | 0% | None | Baseline |
| Days 2–30 | +12% per day (up to 348%) | Strength I, Speed I | — |
| Days 31–66 | 0% growth (plateau) | Strength I, Speed I | — |
| Day 67+ | 120% | Strength IV, Speed IV | Mutation active + Resistance I |
| Days 99–110 | 120% (spike) | Strength IV, Speed IV | Mutation + Resistance I |
| Day 500+ | 999% (extreme) | Strength VII, Speed IV | Mutation + Resistance I + Regeneration III |
Zombie Loot
Killing a Worldfall Evolved Zombie can yield:
- Military Supply Crate (0–2, improved with Looting enchantment)
- Rare player-kill drops (~2.5% base chance, improved with Looting): Iron Sword, Arrows, or Iron Ingots
Monster Replacement
All hostile mobs that spawn within 64 blocks of any player are instantly converted into Worldfall Evolved Zombies. No vanilla hostile mob survives — the entire monster population is the Evolved Zombie.
Baby Zombies & Jockey Behavior
Baby variants of the Evolved Zombie can spawn. They are faster (base speed 0.35) and can mount adult zombies as jockeys, creating mounted zombie pairs.
Drowning Conversion
If a Worldfall Evolved Zombie enters water for 30 seconds, it converts into a standard Drowned — a brief reprieve from the evolved threat in aquatic environments.
Progression And Strategy
Days 1–30 are your window to build up resources. The zombies grow 12% stronger every single day, so treat day 1 as your most generous opportunity to loot, fortify, and craft better gear.
Days 31–66 offer a plateau — zombie power stops climbing but remains dangerous. Use this time to stockpile Military Supply Crates from zombie kills and upgrade your weapons and armor.
Day 67 is a turning point. The MUTATION warning appears on your HUD. Zombies gain Resistance I on top of their existing buffs, making them noticeably harder to kill. Prioritize Looting-enchanted weapons to improve crate drop rates.
Days 99–110 see a brief power spike back to full mutation levels — do not get complacent if you survived the plateau.
Day 500+ represents the endgame. Zombies hit 999% evolution, gain Regeneration III, and become extremely difficult to kill. Reaching this point is a true test of everything you have built. The safe houses, while sturdy, have iron doors that zombies can break — reinforce or relocate as needed.
Tip: Keep Military Supply Crates in reserve rather than opening them all at once. Their splash potions and food can be life-saving during a night siege.
