Zombie Hardcore
Zombie Hardcore changes the zombies in a world so that they are stronger, faster and active during the day, and it adds zombie types that break blocks.
What it does
Zombies in the mod are stronger and quicker than the vanilla versions, and they keep attacking after sunrise because they do not burn in sunlight. Zombies can also break through blocks, so a sealed shelter gives less protection than it does in the base game. The mod does not change other creatures, so they remain in the world and can draw zombies away from a player during a fight.
The mod works on Forge and NeoForge across 18 release versions, 1.20.1 – 1.21.11. Client and server both need it, so the server and every player must run it. Zombie Hardcore is published under All rights reserved and is not open source, although its source code is public. The latest Forge file is 1.0.10-zombie-types for 1.20.6, and the latest NeoForge file is 1.0.11 for 1.21.11.
Key features
Stronger zombies
Zombies deal significantly more damage, so each encounter with them is more dangerous than in vanilla.
Daylight activity
Zombies stay active through the day and do not take damage from sunlight, so there is no safe period to wait out.
Block-breaking zombies
Zombies break through blocks to reach a player, so walls and other enclosures do not stop them.
Increased speed
Zombies move faster than in the base game, leaving a player less time to react.

How it compares
The Zombie Apocalypse Mod is a NeoForge-only mod for 1.21.1, and only its client is required, with the server optional. Zombie Take Over runs on Forge and NeoForge for 1.20.1 – 1.21.5 and is server-side only, so players can join without installing it. Zombie Hardcore differs from both by running on client and server together on Forge or NeoForge.
