Description:
.mcaddon file — it applies automatically to any world you add it to.Crimson Doomsday turns a standard Minecraft world into an automatic, escalating apocalypse. The mod tracks the in-game day count and, at three key thresholds, triggers increasingly severe events — from a blood moon to full end-of-world disasters. Everything happens on its own; you just have to survive.
| Feature | Description |
|---|---|
| Blood Moon (Day 5+) | Crimson sky, red rain, thunder, darkness effect outdoors at night |
| Mob Aggression (Day 5+ nights) | All mobs — including passive ones — seek out and damage players after dark |
| Extreme Aggression (Day 8+) | Hostile mobs gain massive stat buffs; all mobs move faster and hit harder |
| End-of-World Events (Day 10+) | Rotating disasters: tornadoes, firestorms, earthquakes, asteroid strikes, lava floods |
| FEMA Announcements | Siren sounds and on-screen title warnings for every stage and event |
The mod runs entirely on autopilot. Your only job is to react to warnings and survive.
[SERVER WARNING] or [FEMA] describe the current threat.All previously spawned hostile mobs receive permanent buffs for the remainder of the night cycle:
| Buff | Level |
|---|---|
| Strength | 255 |
| Speed | 10 |
| Resistance | 4 |
| Health Boost | 20 |
Rotating disaster events fire repeatedly. Each is announced with a siren and FEMA message:
| Event | Effect |
|---|---|
| Earthquake | Camera shakes violently; outdoor players take 6 damage |
| Tornado | Smoke vortex appears; nearby entities (including players) are launched into the air |
| Firestorm | Spreading fire ignites across the landscape |
| Asteroid Strike | 5 TNT blocks rain down within ~18 blocks of each player, each accompanied by a huge explosion |
| Blood Rain / Lava Oceans | Loaded water converts to lava; red rain persists |
A final FEMA broadcast plays: "Please stay calm and God bless you all."
Days 1–4 — Preparation window. This is your only calm period. Use it to:
Days 5–7 — First escalation. Learn the night rhythm. Stay inside at night and scout during the day only. Passive animals become dangerous after dark, so keep livestock secured underground.
Days 8–9 — Near-impossible combat. Avoid direct fights. Even fully armored players can be killed in one hit by Day-8-buffed hostiles. Traps, height advantages, and ranged attacks are your best tools.
Day 10+ — Pure survival. Focus entirely on weathering disaster events. Keep a roof over your head at all times. Underground bunkers are safest — tornadoes and asteroids target the surface. Listen for sirens and take cover before each event resolves.
Tip: There is no win condition — the goal is to survive as many days as possible. Challenge yourself to reach Day 15 or beyond!
