ChaosZPack [Lost Cities] Abandoned / Zombie Apocalypse
ChaosZPack [Lost Cities] Abandoned / Zombie Apocalypse is a Forge pack that adds abandoned buildings and horror-themed structures to worlds generated with the Lost Cities world style.
What it does
Once the mod is loaded, the Lost Cities world style gains a set of extra structures: two abandoned buildings, a crashed helicopter, a gas station, scattered houses, detailed small, medium and restaurant shops, a fire station, and two huge skyscrapers alongside many tall buildings. The author counts 16 unique structures in total, and a gallery world type lists six of them. Players are asked to select the testworld worldstyle before creating a world, so the new structures generate.
The mod also adds horror elements and immersive weathering to the generated areas, and its loot tables include TaCZ gun loot. Building surfaces were reworked to use modded blocks, which the OWZA development team's buildings were adapted to support. Two dependencies complete the setup: Keerdm's Zombie Apocalypse Essentials is recommended for the zombie side, and [TaCZ] Timeless and Classics Zero is required.
The mod is published for Forge only, for 1.20.1, with the latest file 1.4.0 dated 2026-03-15. A server running it needs every connecting player to have it too. It is released under All rights reserved and is not open source.
Key features

TaCZ loot tables
Loot in the structures includes items from the TaCZ gun mod, so searching a building can turn up firearms.

How it compares
D3dykcea's Horror Structures is a Forge server-side only mod for 1.20.1, released under All rights reserved and not open source, so players join without installing it. Nolando Apocalypse is also Forge server-side only for 1.20.1 under All rights reserved. The Lost City and Naturalist Lite is a Forge client and server mod for 1.20.1 under All rights reserved, so it needs to be on both sides like this mod.
