The Hordes Mod (1.21.1) – Massive Zombie Attacks and Infections

The Hordes Mod is a Minecraft mobs and game-mechanics mod that adds monster horde invasions and zombie infection for Minecraft Forge and NeoForge.

Vanilla survival can become predictable once you have walls, beds, and a steady food supply, and that is exactly the problem this mod tries to solve. Instead of letting every night blur together, it creates scheduled horde attacks, higher stakes around zombies, and a reason to care about infection before it turns into a death spiral. With more than 1 million downloads on Modrinth, The Hordes Mod clearly has an audience of players who want survival to stay tense after the early game.

Key Features of The Hordes Mod

• Night horde invasions — On configurable nights, monsters attack in waves from midnight until morning. This matters because your base stops being a passive shelter and starts feeling like something you actually have to defend, which makes fortifications and preparation feel worthwhile again.
• Configurable invasion timing and mob setup — The nights when hordes appear, the mobs you can encounter, and the time windows can all be adjusted. That flexibility is important because it lets you tune the experience for a harsher survival run or a lighter challenge instead of being locked into one difficulty style.
• Zombie infection for players and horses — If infection is enabled, a zombie hit can start a countdown that ends in transformation after five minutes or on death. That adds a real consequence to close combat, and it makes even a single bad encounter feel memorable instead of disposable.
• Curable infection with configurable rules — By default, a golden apple can cure infection, and the cure item can be changed to another consumable through configuration. For players, that means the system feels threatening without being unfair, because you still have a recovery path if you act quickly.
• Zombie players and drowned replacements — When a player dies from infection, or when the optional setting is enabled, a zombified version of that player can spawn carrying their items, with drowned appearing instead if the death happens underwater. That is a smart survival twist because your gear is still in the world, but reclaiming it becomes a risky fight rather than a simple corpse run.
• Expanded zombification options — Optional settings can extend zombification to villagers and to compatible mobs from other mods if a matching zombie variant exists, and version 1.3.0+ supports custom textures for similar mobs. In practice, this helps the mod feel more consistent across a modpack instead of only affecting a narrow set of vanilla targets.

How to Install The Hordes Mod

1. Choose the correct loader for your Minecraft version: use NeoForge for the listed 1.21.1 and 1.21 releases, or use Minecraft Forge or NeoForge where both are listed.
2. Match the mod file to your exact Minecraft version. The project lists support across multiple releases, including 1.21.1, 1.21, 1.20.1, 1.20, 1.19.x, 1.18.x, 1.16.5, and 1.12.2.
3. If you are installing a Forge build, add Atlas Lib first, because it is required for Forge versions of the mod.
4. Place the downloaded mod file into your Minecraft mods folder, then start the game with the same loader profile you installed.
5. After launch, review the config options or datapack support if you want to tune invasion nights, infection behavior, cure items, or which mobs can be affected.

Pros and Cons

Alternatives to The Hordes Mod

• Bloodmoon — A good pick if you want nights to feel more threatening and event-driven without focusing on infection.
• Zombie Awareness — A complementary choice for players who want zombie encounters to feel more dangerous and persistent.
• Enhanced Celestials — Worth a look if you enjoy survival pressure tied to recurring world events and changing night-time conditions.

Frequently Asked Questions

Does The Hordes Mod work on Forge and NeoForge?

Yes — the project supports both Forge and NeoForge on the listed versions, but 1.21 and newer listed releases are NeoForge-only. If you are installing an older supported build, check the matching loader before downloading.

Do I need Atlas Lib for The Hordes Mod?

Yes — Atlas Lib is required for Forge versions. No Forge-style extra dependency is mentioned for the NeoForge path in the data provided.

Can you cure infection in The Hordes Mod?

Yes — by default, a golden apple cures infection. The mod also allows the cure item to be changed to another consumable through configuration, which is useful if you want a stricter or more generous survival balance.

What happens if a player dies from infection?

A zombified player spawns in their place — and it can carry that player's items. If the death happens underwater, the replacement can be a drowned instead, which adds another layer of danger to ocean or river deaths.

Can I customize horde nights and mob behavior?

Yes — invasion nights, mob encounters, and the relevant times of day are configurable. There is also datapack support in version 1.2.0+ for players who want more control over how the system behaves.

Does the mod affect villagers and other modded mobs?

Yes — optional settings can extend zombification to villagers, and the config can add zombie variants from other mods when a matching zombie form exists. Version 1.3.0+ also supports custom textures for similar mobs, which makes those conversions easier to present cleanly.
