7 Days to Die Blood Moon Configuration

How to configure blood moon horde frequency, zombie count, and difficulty on your 7DTD server.

Every 7th in-game day, the blood moon rises and a relentless zombie horde attacks. Here's how to configure it.

Blood Moon Settings

All settings are in serverconfig.xml:

<property name="BloodMoonFrequency" value="7" />
<property name="BloodMoonRange" value="0" />
<property name="BloodMoonWarning" value="8" />
<property name="BloodMoonEnemyCount" value="8" />

Setting	Default	Description
`BloodMoonFrequency`	`7`	Days between blood moons. Set to `0` to disable entirely.
`BloodMoonRange`	`0`	Random variance in days. If set to `2` with frequency `7`, blood moon can occur day 5–9 instead of exactly day 7.
`BloodMoonWarning`	`8`	In-game hour the sky turns red (22:00 = 10 PM). Set to `-1` to disable warning.
`BloodMoonEnemyCount`	`8`	Max alive zombies per player during the horde.

How the Horde Works

Sky turns red at the warning hour (default 10 PM / 22:00)
At nightfall (22:00), the horde begins — zombies know exactly where every player is
Zombies spawn continuously, up to BloodMoonEnemyCount alive per player at once
The horde ends at dawn (04:00 / 4 AM)
Zombie composition depends on player Game Stage — higher Game Stage = tougher zombies

Zombie Count Math

BloodMoonEnemyCount is per player, and it interacts with MaxSpawnedZombies:

4 players × count of 8 = up to 32 simultaneous blood moon zombies
The global MaxSpawnedZombies cap still applies
If the global cap is lower than the per-player total, some players may see fewer zombies

Common Configurations

Disabled (No Blood Moons)

<property name="BloodMoonFrequency" value="0" />

Frequent Hordes (Every 3 Days)

<property name="BloodMoonFrequency" value="3" />
<property name="BloodMoonEnemyCount" value="12" />

Random Blood Moons (Unpredictable)

<property name="BloodMoonFrequency" value="7" />
<property name="BloodMoonRange" value="3" />

Blood moon occurs randomly between day 4 and day 10, then 11–17, etc.

Brutal Horde Night

<property name="BloodMoonFrequency" value="7" />
<property name="BloodMoonEnemyCount" value="16" />
<property name="ZombieBMMove" value="4" />
<property name="BlockDamageAIBM" value="150" />

Game Stage and Zombie Composition

The zombies that spawn during blood moon scale with each player's Game Stage, which increases based on:

Player level
Days survived
Number of party members nearby

Higher Game Stage = more feral zombies, radiated zombies, demolishers, and cops in the horde.

💡 Tip: If blood moons feel too easy, increase BloodMoonEnemyCount before raising GameDifficulty — more zombies is a bigger challenge than just tougher individual zombies.
