Zombie Nightmare Expansions - Undead Horror Monsters

by vllax

Zombie Nightmare Expansions adds a set of undead horror monsters with unique mechanics, each with its own behavior and drops, for Forge and NeoForge players who want more hostile mobs.

ForgeNeoForgeClient and serverMIT License1.19.2 – 1.21.1

What it does

Creepy undead entities are added to the game, several with mechanics of their own. One large monstrous zombie with hanging entrails seeks out players and cows, and a stationary creature disguises itself as a normal player skin until it moves and reveals its true form. Some mobs hang from ceilings, while a huge demon-like zombie can fly, walk and spit projectiles. Mobs appear rarely in overworld biomes, and spawn rates can be configured for each one, including disabling specific mobs.

The mod is client and server, so the server and every player need it. Files are published for Forge and NeoForge for 1.21.1 as the latest release, with five game versions 1.19.2 – 1.21.1 in total. One optional dependency, Arthropod Phobia Expansions + Horror Bosses, adds more content, and Mini-boss Boss Bars adds boss display. The author plans more mobs for future updates. The code is covered by the MIT License and is not open source.

Key features

  1. Corrupted heart taming

    A strong rideable mob can be tamed with 10 corrupted hearts, and taming can be disabled in the config.

  2. Shockwave attacks

    A huge zombie smashes the ground and sends out block shockwaves with knockback, which can be jumped over to evade.

  3. Summoning staff

    A staff made from Deathly Onyx repulses nearby undead when held, and a charged left click stores up to 5 summons to call crawling minions.

  4. Terrain camouflage

    One mob changes its colour to match nearby stone, deepslate and other blocks, and this can be disabled in the config for tuff, granite, diorite, andesite and netherrack.
