UFO Investigator Aspiration (originally by r3m)
I decided to make this mod a separate post, because it will be easier for me to handle stuff.
This is a mod created originally by r3m and then maintened for some time by Itsmysimmod. Then I took over its maintenance.
Aspiration can be now used in Base Game only, however it will not have few features that will work only with Get to Work EP, especially all features related to Aliens (since Aliens were added with GtW EP). I edited some interactions so they can work with base game as well - e.g. Analyse personality and Transmute interaction are now a base game interactions if you drink Alien Juice as an Alien Guru.
You need XML injector for this mod (the current version).
Original description of the mod: link
If ever something happens to the MTS site, I am copying this description here as well.
Description:
Back in the days of TS2, Knowledge Sims were obsessed with aliens and would constantly roll wants to be abducted. I really liked that, so I wanted to bring it back to The Sims 4 in the form of a new aspiration.
Let me introduce you to the custom UFO Investigator aspiration! This a knowledge aspiration focused on maxing the Rocket Science skill and visiting the Alien World of Sixam.
Milestones:
Stargazer
Achieve Level 3 Rocket Science Skill (75)
Stargaze for 6 Hours (75)
Conspiracy Theorist
Collect 3 Alien Species (250)
Collect 3 Space Prints (250)
Collect 2 Space Rocks (250)
Contactee
Achieve Level 6 Rocket Science skill (500)
Reach Level 4 of the Scientist or Astronaut career (500)
Unmask 3 Aliens (600)
UFO Investigator
Achieve Level 10 Rocket Science skill (1500)
Travel to Alien World (750)
Collect 4 Geodes (750)
Reward Trait:
Those Sims who complete all the requirements of this aspiration will receive the Alien Guru trait. These Sims are very knowledgeable about aliens and their powers. In particular, Alien Gurus:
Can prepare Alien Juice and Space Energy Drink,
Will always get Focused after abduction,
Can transmute metals, revive dead alien collectibles, erase memories, empathize and analyze the personalities of other Sims,
Can use their cell phone to contact aliens,
Know the secret handshake of aliens.
Calling Aliens:
After thoroughly studying the lives of extraterrestrials, Alien Gurus have came up with a clever way to communicate with aliens. Yea, it's using their cell phone. Click on the Entertainment category in your Sim's phone to access this new interaction.
Interaction Summon Aliens
Pick a Sim and aliens will come to abduct them inmediately.
Only teens or older Sims can be picked. Aliens cannot be picked.
The caller will get a slight Fun and Social boost.
They will also build Mischief skill.
Geeks, Goofballs and abductees with the Cheerful trait will gain relationship points with the caller (unless they're Hot-Headed or Squeamish). Other Sims will react negatively.
Male abductees have a 50% of returning pregnant.
Other Changes:
I have included several whims that are exclusive to Alien Gurus and Sims who have selected the UFO Investigator aspiration track.
Additionally I have included some changes to a few game mechanics:
Aliens and half-aliens can now prepare Alien Juice and Space Energy Drink.
Squeamish Sims won't get Focused after alien abductions.
Sims in the Astronaut career will always get Focused after returning from an abduction.
Sims cannot unmask fake aliens (i.e., Sims who drank the Alien Aura Serum).
Fake aliens can now revive dead alien collectibles and transmute metals.

I took out this opportunity and translated mod to Polish. Now there are following language versions available:
English (by Itsmysimmod)
Spanish (by Itsmysimmod)
Polish (by me)

Compatibility:
It should be compatible with Alien Abduction Yields Collectibles Mod.
I updated my mod for the last changes within Aliens Reloaded mod (by Kayaker) to make it compatible with this mod, (at least as much as I could, there are still some tiny differences, but that should not be a big deal, you can ignore any notifications about that if there are any).
Change log:
05/07/2026 - tiny tuning correction after the 30th of June patch. Added compability with Aliens Reloaded mod by OneMoreKayaker (at least as much as I could, there are still some tiny differences, but that should not be a big deal). This aspiration should be compatible with Alien Abduction Yields Collectibles Mod.
28/02/2026 - updated for all February patches
7/12/2025 - not patch related, this update included some fixes, improvements and changes, also PlumbBuddy manifest was added. Details what exactly was changed for this mod can be found in this post: https://www.patreon.com/posts/mods-update-145212977

Hello. So you’re saying this: “Alien Gurus have come up with a clever way to communicate with aliens. Yeah, it’s using their cell phone. Click on the Entertainment category in your Sim’s phone to access this new interaction.” My Sim completed the aspiration and earned the Alien Guru trait, but there’s no such option in that category (or anywhere else) on their phone. That's sad—that's what I wanted most. I'm also using the Aliens Reloaded mod. Do you have any idea what I'm doing wrong, please? Thank you. ♥
Hi, so I'm not an original creator of this mod and all the description and text was written by them. I guess the interaction from trait reward description means Summon Aliens and it's meant to abduct some other Sim. And this interaction appears, if you have xml injector. Do you want some other interaction to communicate with aliens? like calling a random alien from the game, so they could talk and ultimately become friends?
I'm tempted to add the Aliens Reloaded mod to the game, but I also have the UFO Investigator mod, so I'm curious to see how they'll conflict. I'm not sure what you mean by "open a mod and remove this file." Do you mean the aspiration, or that mod by Kaykaer? And do you mean I should just delete that one file from the folder in Documents? Or do I need Sims 4 Studio or something like that? I don’t understand what deleting it will do. Who gets what buff... Thank you very much.
From Kayaker: "The abduction tuning isn't an issue anymore. I've updated that on my end and that file is identical between the both of us. So no matter whose tuning loads you'll see the correct intended outcomes. v4.0 did add two new conflicting files, which are there recipes for Alien Juice and Space Energy. UFO Investigator makes it so that the Alien Guru trait will unlock these recipes. Aliens Reloaded makes them available to generation one full aliens (ie, they were born on Sixam and learned it there) and those with Alien Lore 5 or higher. I've added support for the Alien Guru trait to both of these recipes as well (you can be in the required careers, a full gen one alien, have high enough Alien Lore, or be an Alien Guru to unlock them), but I don't believe Ilkavelle has had time to update UFO Investigator for compatibility / might not be aware that AR has been updated. So depending on whose mod loads first the recipes may be inconsistently available."
"Male abductees have a 50% of returning pregnant." - does this also apply to sims (male or not) who have the cas option selected for 'neither' when it comes to offspring?
I was trying to check this out, but honestly I don't know. The interaction added in this mod is a copy from the interaction from the game, with the only difference that it increases the chances. But I noticed that my Sims, male Sims being abducted recently in the game quite often (by in-game abduction, not this one from this mod) they never get pregnant. Never. And I start to think that simply this is some kind of oversight from EA part. I don't know. What I can see in my mod - it should work as in game abduction, but it no where says about this option: cas option selected for 'neither' when it comes to offspring. Not in my mod, not in game files.
Tray importer show this has conflicts with Alien Overhaul (https://www.nexusmods.com/thesims4/mods/2342) and AI says they won't work together without massive issues. Is there any way to make them compatible?
I will check if I can make it compatible, but I'm sure AI is wrong about causing it causing issues in this case. If anything, simply some small feature from my mod will not work because it will be overwriiten by Alien Overhaul mod. That's not massive, that's simple overwriting of the way things work. I guess it's about the alien drinks that with my mod can be created when you finish my aspiraiton.
I'm testing the aspiration now, and it seems stargazing doesn't work for the first level. My sim is spending hours on his back, without the aspiration registering the stargazing.
Oh! So to complete it, you need to use a telescope or an observatory. When the aspiration was created originally, I think the stargazing from the ground was not yet a thing. Also it is about looking for aliens, so I never thought about adding stargazing from the ground, since you can't really spot anything in the space with just an eye. But I might check if that's possible to include this interaction as well. If all these interactions share at least one same tag, then yes. If not, I'd prefer to stay with telescope interactions.
Can't believe how perfect this is for my my current save, thank you so much!!
this sounds like so much fun thank you
