About ZergFaction

From Factorio Mod Portal

Allows players to build swarm-related structures that spawn friendly biter units. These units will assist the player and automatically attack enemy factions.

1.0.3

  1. Add Swarm Command — Use the selection tool to gather friendly Zerg units. They will move to your position.

2.Fixed the issue where dependencies were displayed incorrectly

This mod requires the Space Age DLC to function properly. (I will add Space Age as a required dependency in the next version of the mod.)

Still wondering what to do with all those biter eggs piling up in your inventory? Well... now you can use them to grow your very own swarm. Ahem.

In theory, it can be compatible with any mod related to biters. It uses a bit of a mysterious method to achieve that, haha~

🧬Zerg Faction Mod for Factorio Zerg Faction is a Factorio mod that introduces a new mechanic where players can create their own swarm of loyal alien units. Using biter eggs, players can construct spawner buildings that generate units and defensive structures over time. These structures form clusters, grow organically, and react dynamically to enemies nearby.

Features Build alien spawners using biter eggs.Zerg spawners auto-cluster and expand by growing new spawners over time. Spawners generate biters and defensive turrets based on local threat. Units spawn in directions facing nearby enemy activity. Includes a capture mechanic: When enemy spawners are destroyed by Zerg forces, there’s a chance they’ll be captured and converted into loyal Zerg nests.

Part of the spawner capture mechanic is inspired by the mod This is Mine.

Special Thanks WeregarurumonX – for inspiring some ideas on swarm expansion and defensive patrols.
