Description
Ultra Doomsday Events transforms your world into a timed apocalyptic scenario that automatically runs from world Day 1 through Day 15 with escalating, server-wide warnings and hazards. The mod sends chat broadcasts, title alerts, action-bar HUD warnings and sound cues each day; on Day 10 the Ultra Max Earthquake strikes with intense camera shake, knockback tremors, pressure damage, explosion and lightning effects, rupture sounds, and local terrain disruption around players. Days 11–15 run as aftershock phases with continued tremors, particles and alerts, forcing players to seek shelter, adapt or rebuild until the cycle ends and an automatic all-clear is announced.
Mod Wiki
Ultra Max Doomsday Events
Quickstart
- Install the
.mcaddonfile and apply both the Behavior Pack and Resource Pack to your world. - Load the world and start a fresh game — the countdown begins automatically on Day 1. No commands or setup are required.
- Watch your chat window and screen titles each in-game day for escalating warnings.
- Prepare yourself before Day 10 — that is when the Ultra Max Earthquake hits. Stock up on food, find shelter underground or in a reinforced structure, and keep your health topped up.
- Survive Days 11–15 of aftershocks, then wait for the all-clear message on Day 16+.
Overview
Ultra Max Doomsday Events turns the first 15 in-game days of any world into a timed, server-wide apocalyptic scenario. From the moment the world loads, the mod begins tracking the current world day and automatically delivers escalating warnings, hazardous effects, and terrain disruption — all without any player input. On Day 10 the catastrophic Ultra Max Earthquake strikes, and Days 11–15 bring relentless aftershocks before the cycle ends and calm is restored.
Every effect is server-wide: all players on the world are affected simultaneously.
What It Adds
The mod adds no new items, blocks, or crafting recipes. Instead it layers a scripted event system on top of the normal Minecraft world:
| Feature | Description |
|---|---|
| Chat broadcasts | Colour-coded server-wide messages every day announcing the current threat level |
| Screen titles | Full-screen title + subtitle alerts shown to every player at the start of each day |
| Action-bar HUD | Persistent status line showing the current day, phase, and a short warning |
| Sound cues | Explosion and anvil-impact sounds tied to daily announcements and tremor events |
| Camera shake | Positional screen shake during the earthquake and aftershock phases |
| Knockback tremors | Players are physically thrown around during quake and aftershock pulses |
| Pressure damage | Periodic 1-point damage hits during the active earthquake on Day 10 |
| Status effects | Slowness and Mining Fatigue applied alongside damage pulses on Day 10 |
| Terrain ruptures | Grass and dirt near players replaced with magma blocks; small pits blasted open; lightning summoned during the earthquake |
| Aftershock particles | Explosion particle bursts spawned near players during Days 11–15 |
| All-clear announcement | A green chat message posted once the cycle ends on Day 16 and beyond |
How To Use
The mod runs entirely on its own. Once the packs are applied to a world, simply play normally. There are no commands to run, no items to craft, and no triggers to activate.

[Ultra Max Doomsday]messages. Each day broadcasts a unique lore briefing describing the growing threat. - Screen title — A large title appears at the start of each day (e.g. MEGAQUAKE COUNTDOWN, WORLD CORE UNSTABLE, ULTRA MAX ALERT) with a subtitle explaining what is happening.
- Action bar — The line just above your hotbar continuously shows the current phase (
DOOMSDAY WARNING,ULTRA EARTHQUAKE ACTIVE, orAFTERSHOCKS ACTIVE) alongside your day progress (e.g.Day 5/15).

Abilities And Mechanics
Day 10 — Ultra Max Earthquake
The earthquake is the centrepiece of the event. While it is active:
- Camera shake pulses continuously at high intensity, making navigation difficult.
- Knockback throws players in random horizontal directions and launches them upward — fall damage is a real threat.
- Damage pulses deal 1 point of damage at regular intervals. Combined with fall damage this can kill unprepared players quickly.
- Slowness II and Mining Fatigue I are reapplied every damage pulse, hampering both movement and digging.
- Terrain rupture fires periodically near each player: grass and dirt blocks in a roughly 5×5 area are converted to magma, a small 3×3 pit is blasted open, and a lightning bolt strikes.
- Explosion sounds play alongside each rupture.
Days 11–15 — Aftershocks
Aftershocks are less frequent and less severe than the main quake but still dangerous:
- Knockback pulses fire every six times less often than during the earthquake.
- A 25 % chance of a mild camera shake occurs each tremor pulse.
- A 35 % chance of a large explosion particle burst spawns near each player during rupture intervals.
- Anvil-impact sounds replace the full explosion audio.
- No direct damage or status effects are applied during aftershocks.
Progression And Strategy
Days 1–4 (Early Warning)
Use these days normally. The mod only sends chat messages and title cards — no physical harm occurs yet. This is your best window to gather resources, craft armour, and build or fortify a shelter.
Days 5–9 (Countdown)
The warnings intensify daily. Continue preparing. Prioritise:
- Full iron or better armour (fall damage from knockback will hurt).
- A stockpile of food for rapid health regeneration.
- A sheltered base away from open grass/dirt surfaces (which will be converted to magma on Day 10).
Day 10 (Survive the Earthquake)
- Stay indoors if possible — terrain ruptures target the blocks beneath you, so being on stone, wood floors, or inside a building reduces disruption.
- Keep moving to avoid staying in one spot when a rupture fires.
- Have a totem of undying or a large food supply ready; the combination of damage pulses, fall damage, and status effects can be lethal.
Days 11–15 (Aftershock Recovery)
- No more direct damage, but knockback and particles continue. Repair your base and replace magma blocks before they cause further hazards.
- The effects gradually feel less intense as the cycle winds down.
Day 16+ (All-Clear)
A green all-clear message appears in chat. The mod becomes inactive for the rest of the world's life. You are free to continue your world without further interruption from the event system.
