Description
.mcaddon and create a new world — the mod applies at world scope.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.

Seven pre-built stone shelters are constructed at world start, one per player (cycling through the list for additional players):
| Safe House | Coordinates |
|---|---|
| Berlin | 0, ~79, 0 |
| Moscow | 500, ~79, 0 |
| Paris | −500, ~79, 0 |
| Rome | 0, ~79, 500 |
| London | 0, ~79, −500 |
| Beijing | 500, ~79, 500 |
| Taipei | −500, ~79, −500 |
Each safe house is a hollow stone room with a Warzone Asphalt floor, an iron door entrance, and a chest inside.
A persistent display appears at the bottom of your screen at all times:
Worldfall Day [X] | Blood Moon: ACTIVE / Dormant | Zombie Evolution [X]% [MUTATION]
Hold the crate in your hand and use it (tap/right-click) to open it. You cannot place it — activating it immediately grants:
Use the command /locate biome com_worldfall_zombie_siege_kehg25c5:worldfall_warzone to find the nearest Worldfall Warzone area if needed.
There are no crafting recipes in this mod. All items are obtained through gameplay:
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 |
Killing a Worldfall Evolved Zombie can yield:
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 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.
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.
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.
