UFO Investigator Aspiration (originally by r3m)
This is a sci-fi aspiration that lets Sims investigate aliens, explore space, and unlock the powerful Alien Guru trait.

UFO Investigator is a custom aspiration for The Sims 4 that expands the Knowledge category with a fully fleshed-out, alien-themed progression. Originally created by r3m and later maintained by IlkaVelle, this aspiration allows Sims to pursue extraterrestrial research, space exploration, and conspiracy-level investigation as a structured long-term goal.

Key Features

Four-Tier Aspiration Track
The aspiration includes four progressive milestones:
  • Stargazer
  • Conspiracy Theorist
  • Contactee
  • UFO Investigator

Each tier guides Sims through tasks such as:
  • Increasing the Rocket Science skill
  • Using the observatory for extended periods
  • Collecting aliens, space prints, and space rocks
  • Gathering geodes
  • Discovering disguised aliens
  • Traveling to Sixam
  • Advancing through deep space missions

Completion Reward – Alien Guru Trait
Upon finishing the aspiration, Sims earn the Alien Guru trait, which unlocks unique interactions and powers, including:
  • Preparing Alien Juice and Space Energy Drinks
  • Transmuting metals
  • Reviving dead alien collectibles
  • Erasing memories
  • Analyzing a Sim’s personality
  • Contacting aliens via phone
  • Performing a “secret alien handshake” with other Gurus

Summon Aliens Interaction
Alien Gurus gain a special phone interaction that allows them to call aliens to abduct a chosen Sim (teen or older). The caller may receive boosts to Fun, Social, and Mischief skill, and some personality types may even gain relationship benefits from initiating the abduction.
