Relentless Undead Siege Mod (1.20.1) – Defend Your Base From Smart Zombie

Relentless Undead Siege Mod transforms ordinary zombies into intelligent hunters that actively break into your base. The mod boosts zombie spawn rates and gives them the ability to hear footsteps from far away. Undead mobs can now dig tunnels, climb ladders, build bridges, and smash weak blocks to reach you. Nighttime becomes a true fight for survival as stronger undead types and red Blood Moon events test your defenses.
