Relentless UndeadMinecraft mod for 1.20.1

Relentless Undead is a mod that focuses on making zombies harder. This isn't a traditionally AI change but rather mechanic focused. Zombies will climb each other to reach your height and ignore heights entirely to pour off high places to reach you.

Frequently asked

Does Relentless Undead work on Minecraft 1.20.1?

Yes. 1.20.1 is the newest Minecraft version Relentless Undead declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which platform or loader does Relentless Undead support?

Forge, NeoForge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Relentless Undead?

On the newest Minecraft version it supports, Java 17 or newer. The requirement comes from the Minecraft version you run rather than from the mod itself, so on an older supported Minecraft the answer is that version's Java, not this one.

How do I install Relentless Undead?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Relentless Undead safely?

Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
