.mcaddon and start a new world (Survival, any difficulty from Easy to Hard)./locate biome com_worldfall_zombie_siege_vaqnlkd4:worldfall_warzone to find the Worldfall Warzone biome and head there.Worldfall Zombie Siege turns Minecraft into a relentless urban zombie apocalypse. The world generates two custom biomes paved with dark asphalt and littered with ruined safe-house structures. Every common mob you encounter is converted into a Worldfall Evolved Zombie, and the game continuously spawns dense hordes around you. A persistent HUD tracks how dangerous the world is getting, and every fifth night brings a catastrophic Blood Moon onslaught. Your goal is to scavenge military gear, shelter wisely, and outlast an ever-escalating siege.
| Biome | Surface Block | How to Find |
|---|---|---|
| Worldfall Warzone | Warzone Asphalt | /locate biome com_worldfall_zombie_siege_vaqnlkd4:worldfall_warzone |
| Carcer City | Blood Asphalt | Present in the world; explore or use /locate biome |
Both biomes feature Rebar Weeds growing from the cracked ground and scattered ruined safe-house structures to scavenge.
| Block | Notes |
|---|---|
| Warzone Asphalt | Solid, grey urban paving; mines in ~1.5 s; moderate blast resistance |
| Rebar Weeds | Decorative foliage; breaks instantly; drops itself |
| Item | Description |
|---|---|
| Military Rifle | Ranged weapon — aim and use to fire; deals 12+ damage scaling with the world's evolution level; stacks to 1 |
| Medkit | Use to instantly restore health and gain 45 seconds of Absorption; stacks to 16 |
Worldfall Evolved Zombie — the primary threat. Replaces all common hostiles and passive mobs. Burns in daylight, can break doors, can climb, and is amphibious. Baby variants are faster. Adults can carry riders. Drops rotten flesh; rare chance to drop an iron ingot, carrot, or potato when killed by a player.
Hold the rifle and use (right-click / tap the use button) while looking at a target up to 48 blocks away. The rifle fires instantly, dealing base damage of 12 plus a bonus that grows as the world's evolution percentage rises. A muffled explosion sound plays on each shot.
Hold a Medkit and use it to instantly heal and gain a 45-second Absorption buffer. Each use consumes one Medkit from the stack. Use it before a fight or when critically low on health. Your movement slows slightly during the short use animation (~1 second).
The action bar is always visible and shows:
Worldfall Day <N> | BLOOD MOON / no blood moon | Evo <X>% | <MUTATION TIER>
Use this to anticipate danger before stepping outside.
Any vanilla hostile mob (zombie, skeleton, spider, creeper, enderman, husk, drowned) or passive mob (cow, pig, sheep, chicken, villager) that spawns or exists within ~48 blocks of a player is immediately replaced by a Worldfall Evolved Zombie. There is no safe mob to rely on for resources — even farms will convert.
Every 5 seconds the game checks how many Evolved Zombies are near each player and spawns up to 8 more at a time, circling 24–48 blocks away. The cap grows with each day:
On days 5, 10, 15, 20 … the onslaught cap jumps to 100. The action bar flashes BLOOD MOON in red. Prepare extra Medkits and find defensible terrain before nightfall.
The world grows more dangerous over time. The current mutation tier is always shown on the HUD:
| Days | Tier | Evolution % |
|---|---|---|
| 1 | RISING | 0 |
| 2–14 | RISING | 12–156% |
| 15–19 | SCREAMERS | up to 168% |
| 20–29 | BLOATERS | up to 228% |
| 30–66 | FERALS | ~348–360% |
| 67–98 | MUTATING | 500% |
| 99–499 | SPIKE | 650% |
| 500+ | EXTREME | 999% |
As evolution rises, the Military Rifle's bonus damage also scales (evolution ÷ 120, rounded down), so the weapon remains relevant late-game.
