Zombie Outbreak: Nightmare
Transform your Minecraft Bedrock world with 100 unique horror creatures and terrifying new looks for zombie horses, piglins, and piglin brutes.
From twisted undead and sinister clowns to small Gremlins and unsettling animal creatures, every encounter brings a different face to your nightmare.
Features
- 100 horror variants with custom models and detailed textures.
- Automatic zombie replacement: regular zombies, husks, drowned, and zombie villagers turn into creatures from the add-on.
- Existing-world support: loaded zombies are replaced, including those encountered as you explore previously unloaded chunks.
- 100 individual spawn eggs available in the Creative inventory.
- Small Gremlins and a baby-sized Sewer Rat.
- Horror zombie horses, piglins, and piglin brutes with custom appearances.
- Original Minecraft skeletons retain their normal appearance and behavior.
Zombie replacement uses the existing Minecraft spawns. The add-on does not create additional waves or increase spawn rates. Creature selection is currently independent of biomes.
