Space Worms Mod

Author of the Space Worms Mod: mlie

Space Worms Mod introduces a dangerous parasitic threat to your colony in the form of alien space worms that infect, gestate, and violently emerge from their hosts. With new research, medical procedures, and customizable infection mechanics, this mod adds a tense survival challenge focused on containment and rapid response.

Space Worms Features

  • Space Worm creature: Adds a new parasitic alien that infects human hosts and reproduces through lethal gestation.
  • Xenobiology research: Unlocks new technology to detect infections and perform surgical extraction of larvae.
  • Surgical procedure: Allows skilled colonists to remove larvae before they hatch.
  • Dynamic infection system: Infection occurs via bites, with configurable chances and behavior through mod settings.
  • Customizable options: Includes settings for infection chance, affecting non-humans, preventing reinfection, and infecting arriving pawns.
  • Incident tuning: Adjustable base chance for worm-related incidents.
  • Re-texture included: High-quality textures by Mashed Space Worms Re-texture Mod are bundled.
  • Mechanoid immunity: Worms no longer infect mech-type pawns.

How it works

  • Initial infection: An infected survivor may arrive via escape pod, potentially spreading the parasite.
  • Gestation cycle: Infected pawns will give birth to a new worm within 24 hours, dying in the process if untreated.
  • Detection: With proper research, infections can be identified through health records.
  • Containment: Without research, placing hosts in stasis can delay gestation.

Tips

  • Act fast: You have limited time to diagnose and operate before the larvae emerges.
  • Quarantine: Isolate infected pawns to prevent rapid spread.
  • Prepare defenses: Newly born worms immediately seek new hosts.
  • Use stasis: Cryosleep can pause gestation if you’re unprepared.

Compatibility notes

  • Gestation timing: Gestation period ranges between 12 and 24 in-game hours.
  • World travel: Traveling while infected may cause issues.
  • Feature limitation: Larvae implantation is temporarily removed for future rework.
