About the Archogenum mod

Archogenum lets you embrace the role of a gene-engineer. Extract, combine, and rewrite the essence of living beings to synthesize unique xenofruits – mutable genetic blueprints that shape your survival, strength, and playstyle.

Important Notice

Archogenum is currently in beta – many features are incomplete or unstable. This is my submission for ModJam 2025, which I joined late due to difficult personal circumstances as a refugee in Argentina. The mod is uploaded early to pass verification, and I don't recommend using it in survival yet until after the jam, as I'll be actively expanding and polishing its systems.

Archogenum is planned as part of a larger series of immersive, thematically connected mods alongside Ars Elixirum and others, focused on roles like alchemist, gene-engineer, and enchanter, all centered on exploration, experimentation, and self-expression.

Features

  • 🧬 Genetic Engineering – Extract genes from creatures and weave them together to create specialized or extraordinary xenotypes.
  • ♻️ Dynamic Xenotypes – Your xenotype isn't permanent. Swap, reforge, and experiment freely with different gene combinations during your journey.
  • 🔥 Environmental Adaptation – Craft xenotypes built for specific environments. For example, become heat-resistant and immune to Wither effects to explore the Nether while running across lava like it's solid ground.
  • ⚔️ Unique Traits & Synergies – Genes define your abilities, resistances, and weaknesses. Become undead and heal from poison, or transform into a hybrid predator with enhanced strength and speed.
  • 🐾 Full Creature Xenotypes – Xenotypes aren't limited to yourself. You can combine traits from any living creature: produce eggs, give milk, drop pork… or even implant xenotype traits into other creatures to boost their productivity, survival, or special abilities. Yes, you can implant milking glands into a friend xD
  • 🧪 Experimental Gameplay – Archogenum avoids grind-heavy mechanics and complicated multi-block setups. The focus is on exploration, experimentation, and creativity.
  • 🧰 Fully Data-Driven – Every gene, trait, and xenotype system is fully data-driven. You can edit existing genes or add entirely new ones without touching a single line of code.

This mod is actively expanding – with more xenotypes, gene interactions, and ancient Archogenes planned. Community feedback and custom gene packs are welcome!

Commands

  • /archogenum gene add – Adds a new gene to your current xenotype.
  • /archogenum gene remove – Removes a gene from your current xenotype.
  • /archogenum gene discover – Unlocks one or all genes in your gene collection.
  • /archogenum gene forget – Locks one or all genes in your gene collection.
  • /archogenum gene give – Gives a gene in an Echo Vessel.
  • /archogenum makeRandomVessel – Gives an Echo Vessel with a random set of genes.

How to install Archogenum

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric, Forge or Quilt

    The loader must match the game version of the mod file, for example Minecraft 1.20.1. After installing it, a separate profile appears in your launcher.

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

Is Archogenum for Forge or Fabric?

Does Archogenum need other mods?

The author lists no required dependencies: the Fabric, Forge or Quilt loader is enough.

Which Java does Archogenum need?

Minecraft 1.20.1 runs on Java 17. If the game closes right after launch, the usual cause is the wrong Java version in the profile settings.
