Biter Born: Swarm Ascendant

You are not the engineer fighting the swarm. You are the swarm.

Biter Born is a Space Age total-conversion overhaul that turns Factorio into a biological infestation campaign. You begin as a vulnerable Queen / Hive Mind and grow outward through biomass, creep, larvae, digestion, mutation, acid biology, brood development, and eventually planetary swarm domination.

This mod is a playable foundation rebuild, not a finished endgame expansion. The current goal is to make the opening loop readable, biological, and stable before deeper systems are layered back in.

Core Fantasy

Biter Born is built around one rule:

The player is not building a factory. The player is growing a living organism.

Instead of clean machines, belts, inserters, and ordinary industry, the hive grows organs, spreads creep, digests matter, mutates itself, and produces brood. Progression is intended to feel like biological evolution rather than mechanical research.

Your early survival loop is based around:

• harvesting biomass
• seeding creep
• growing living organs
• refining nutrient pulp
• mutating new capabilities
• producing larvae and brood
• weaponizing acid biology
• expanding the hive’s territory

The long-term vision is a true swarm total conversion, where the map becomes living territory and the player develops from one hungry body into a distributed hive intelligence.

Foundation Rebuild Direction

Biter Born has been refocused around a tighter, more alien first-hour experience.

The intended opening progression is:

Queen survival → biomass → creep seeding → larval nest → gastric / digestive chamber → nutrient pulp → mutation chamber → acid biology / brood strain → early hive control

Advanced assimilation, complex hive infrastructure, command pheromone variants, and late-game organ systems are deferred from the opening experience until they can be rebuilt properly around the Bio-Engine foundation.

This keeps the public release line focused on a stable living-hive baseline instead of overwhelming the player with half-finished late-game systems.

Bio-Engine Foundation

Biter Born is built on a Bio-Engine framework that tracks the hive as a living colony rather than a normal factory.

Current and developing foundation systems include:

• Creep saturation checks
  Creep is the living substrate that supports hive structures.

• Organ support and necrosis scaffolding
  Organs can be tracked for creep support, unsupported state, and future decay / failure behavior.

• Tissue tension support
  Connected creep networks can contribute to the health and efficiency of the colony foundation.

• Metabolic reserve / BMR tracking
  The colony has the beginnings of a shared biological upkeep model.

• Colony vitality feedback
  The hive can report its overall metabolic condition.

• Worker Grub logistics foundation
  Early grub logistics begin replacing ordinary mechanical transport as a biological carrier system.

• Metabolic byproducts
  Biter Born is moving away from ordinary factory pollution toward biological waste and hive-specific environmental pressure.

• Queen death crisis hooks
  The Queen is intended to matter as the living center of the colony, not just as a reskinned player body.

These systems form the foundation that future Biter Born versions build on.

Biological Progression

The rebuild removes the old feeling of “everything all at once” and rebuilds progression around biological ownership.

The early game emphasizes:

• Raw Biomass as the first survival material
• Creep Seeds / Tumors as the beginning of territorial growth
• Larval systems as the beginning of brood development
• Gastric / digestive production as the bridge from raw feeding to refined growth
• Nutrient Pulp as early biological energy
• Genetic Memory / Genetic Catalyst as mutation materials
• Acid biology as the first combat / survival specialization
• Brood foundations as the first step toward swarm expansion
• Basic pheromone direction as the first step toward command

The Mutation Chamber is the heart of early evolution rather than a renamed vanilla lab.

First-Hour Focus

The most important part of the rebuild is the first stretch of gameplay.

In practical terms, the foundation is focused on:

1. Wake as the Queen.
2. Gather biomass and chitin.
3. Seed creep.
4. Grow the first hive organs.
5. Refine nutrients.
6. Begin mutation research.
7. Unlock acid biology and brood foundations.
8. Start becoming a real hive instead of a lone creature.

The early game should feel hungry, constrained, and alien. You are not supposed to begin with a complete factory toolset. You are supposed to bootstrap a living colony from almost nothing.

Worker Grubs

Worker Grubs are the first biological logistics layer.

They are small early haulers that move materials between nearby supported organs. They are intentionally slower and shorter-ranged than a mechanical logistics solution. Their job is to make the first hive feel alive without turning the early game back into normal belt-and-inserter factory play.

Worker Grubs:

• pull from living organ outputs and Storage Sacs
• insert into real recipe input slots
• ignore fuel slots
• do not fill Storage Sacs
• operate at a limited local radius
• are meant to support nearby organs, not replace all logistics

What Is Deferred

To keep the rebuild playable and focused, several previous or planned systems are intentionally kept out of the starting experience:

• advanced assimilation
• engineer-prey economy
• complex hive infrastructure
• multiple command pheromone variants
• advanced living logistics
• late-game organs
• excess early recipes
• grey duplicate placeholder icons
• vanilla-like logistics reskins
• planetary strain systems
• apex growth systems

These are not necessarily gone forever. They are being re-evaluated for future versions so they can return as real biological systems instead of clutter.

Future versions will rebuild these systems on top of the Bio-Engine foundation rather than returning to ordinary factory logic.

Remote Compatibility API

Biter Born includes a remote interface for compatibility mods.

The remote API allows other mods to query or interact with the Bio-Engine layer, including creep support, organ registration, organ status, grub logistics status, tissue tension, and metabolic reserve hooks.

The interface is intentionally narrow while the rebuild stabilizes. It exists so other modders can begin integrating with the biological systems without depending on unstable internal implementation details.

Recommended For

Biter Born is for players who want a very different kind of Factorio run.

You may enjoy this mod if you want:

• a biological swarm fantasy
• a hostile early survival curve
• creep-based territory expansion
• mutation-driven progression
• brood and hive mechanics
• less emphasis on normal factory layouts
• a total-conversion direction rather than a small content add-on

This is not intended to be a normal vanilla-plus mod. The goal is not to add a few biter-themed machines to ordinary Factorio. The goal is to gradually replace the factory mindset with a living infestation economy.

Fresh Save Recommended

A fresh save is strongly recommended for the current foundation line.

The rebuild restructures progression, technology requirements, early unlocks, runtime state, and several Bio-Engine systems. Old saves may load, but they are not the intended experience for the rebuild.

For the intended experience, start a new game.

Current Status

Status: active foundation rebuild
Recommended save type: fresh save
Target: Factorio 2.0 / Space Age
Release line: foundation rebuild

The current public build should provide the reset baseline for the first-hour swarm loop, but it is not the final form of the mod.

Upcoming work is expected to focus on:

• first-hour playability polish
• better visible creep feedback
• deeper necrosis consequences
• improved Worker Grub logistics
• stronger metabolic pressure
• better Queen crisis / recovery mechanics
• more distinct early-game visuals
• replacing remaining weak or vanilla-feeling content

Feedback Wanted

The most useful feedback right now is about the early experience:

• Is the starting loop understandable?
• Are any recipes blocked?
• Are any required items impossible to produce?
• Are too many things visible at the start?
• Do any icons still look too grey, samey, or placeholder-like?
• Does the mod still feel too much like renamed vanilla Factorio?
• Does the Queen feel like the center of the hive?
• Does creep feel important enough?
• Do Worker Grubs feel like a useful first biological logistics layer?
• Does the first mutation path make sense?

Screenshots are extremely helpful, especially of the crafting menu, technology tree, early organs, and any confusing recipe chains.

Long-Term Design Direction

The long-term vision is a full swarm total conversion:

• grow organs instead of factories
• spread creep as living territory
• digest prey and terrain into biomass
• mutate new biological systems
• command brood castes
• replace vanilla logistics with grub and pheromone systems
• turn engineer civilization into food, memory, and later assimilation material
• adapt the hive across Space Age planets
• ascend from one hungry Queen into a planetary and eventually stellar swarm

The rebuild starts here:

one Queen, one infestation, one living foundation.
