Xenogenesis
A biomechanical horror mod inspired by Alien and Prometheus. Discover sealed underground structures, parasitic life cycles, facehuggers, and xenomorph-like organisms waiting to be unleashed.
Xenogenesis is a biomechanical horror mod inspired by
Alien (1979), Prometheus, and the disturbing art of H. R. Giger.
Beneath the world, something waits.
Xenogenesis transforms the underground into a place of ancient design and living machinery.
Hidden far below the surface are sealed structures—black stone, organic shapes, and chambers that breathe softly in the dark.
These places were not built to be found.
Within them lies a parasitic life cycle engineered with purpose. Eggs remain dormant until disturbed. Creatures do not roam freely—they are released. Once awakened, the infection spreads through hosts, reshaping flesh into something violent, efficient, and unmistakably alien.
The mod avoids surface-level chaos and instead focuses on slow discovery, biological horror, and irreversible consequences.
- Deep underground biomechanical structures
- Organic egg chambers containing parasitic organisms
- Facehugger-style creatures that seek living hosts
- Host-based incubation and violent emergence
- Adult organisms capable of converting biomass into new eggs
- Emphasis on tension, atmosphere, and rarity
- No random surface spawning or arcade-style encounters
Screenshots, GIFs, and videos showcasing structures, creatures, and encounters will appear here.
- Minecraft versions: Latest supported version only
- Mod loaders: Fabric, NeoForge
- Multiplayer: Supported
- Modpacks: Compatible with most packs unless otherwise stated
What Minecraft versions does this mod support?
Xenogenesis is developed for the latest Minecraft version. Older versions are not and will not be maintained.
Will this be ported to older versions or other loaders?
No. The mod is intentionally focused on its supported platforms only; however, this may change post-release.
Can I include this mod in a modpack?
Yes. Modpacks hosted on CurseForge or Modrinth are allowed.
Can I make videos or showcases?
Yes. Showcases, streams, and videos are welcome.
Will you add guns, queens, tameable creatures, or sci-fi tech?
Yes. Xenogenesis deliberately is made to have firearms, advanced technology, hive mechanics, and tameable organisms added to preserve its horror-focused identity but also allow player to have their own individual experience.
How do I encounter the creatures?
By exploring deep underground and disturbing structures that were never meant to be opened.
What happens if I get infected?
Some infections can be treated if discovered early. Others are permanent and lethal.
