Rent Server with this Mod

About this Mod

What does the mod add?

The mod adds a new type of zombie called "The Crawling One," a zombie that drags itself across the ground using its arms.

Recommendations:

The mod is more suitable for world types and map styles with a zombie apocalypse theme, as it integrates better with the environment.

Compatible with mods like Sounds Physics Remastered and True Darkness; both mods work correctly with this mod.

Extra:

The mod is still in development and soon there will be more texture variety and new types of zombies.
Requires the Geckolib mod to work.

Frequently Asked Questions

Expansion Z server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Expansion Z compatible with forge?

Expansion Z officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Expansion Z – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Expansion Z consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
