Undead Nights Mod (1.21.8, 1.20.1) redefines nighttime survival by introducing large-scale zombie invasions that test your base defenses, combat readiness, and resource planning. Compatible with Fabric, Forge, and NeoForge, this mod adds configurable Horde Nights where relentless, enhanced zombies swarm players under the cover of darkness. Inspired by survival games like 7 Days to Die, this is perfect for players looking to inject tension and urgency into their Minecraft experience.

Undead Nights Mod
