Apocalypse Overwrite Data Pack introduces a brand new Minecraft world where zombies have overtaken it. The zombies in this data pack have been buffed to a ridiculous level. They can now spawn as a group even in the daytime, they are immune to sunlight, they are extremely fast, and can even break blocks. Besides the modification to Zombies, this data pack also includes new biomes, structures, and generations to bring a modern feel to Minecraft. You can find various abandoned cities, airplanes, and more. Loot buildings, run from Zombies, and survive!
Features:
- New structures, world-gen, biomes, and modifications to zombies depend on the difficulty.
