The Sims 3 Alien Powers & Abilities (Complete Guide)

Sims 3 Alien Powers

The Sims 3 alien powers include the brain power motive, mental scans, transmuting, mind control, re-combobulation, draining or boosting other Sims, probing, and the ability to drive a UFO. Plus, there’s a special career only aliens can have.

Aliens were introduced to The Sims 3 in the Seasons expansion. And for the first time, they were more than just humans with green skin. Now, they had their own set of abilities that made them more interesting to play.

These abilities are available to any full aliens in the game – visiting aliens you move in AND those born from abduction. Sim-alien hybrids will NOT have access to alien powers. (Abduction babies are always considered full aliens, not hybrids).

Brain Power Motive

Teen, adult, and elder aliens don’t have the energy motive like other Sims. Instead, they have “brain power.” Children and toddler aliens use the energy motive until they become teens.

The Sims 3 Alien Brain Power
Aliens aged teen and up have brain power instead of the energy motive.

Sleeping offers no benefit to aliens. Although they can sleep if you direct them to, it will not restore their brain power.

Instead, click on your alien Sim and choose “Restore Brain Power.” The Sim will sit down somewhere and go into a “trance” with her mouth open and palms facing up. Strange lights float around her head as brain power is restored.

Sims 3 Alien Restore Brain Power
An alien restores brain power by going into a trance-like state.

Alien Sims may autonomously restore their brain power when it drops too low.

Another way to restore brain power is by consuming space rocks, which you’ll have to collect out in the world. I always keep a few space rocks in my alien’s inventory for emergencies.

Click on a space rock and choose “Consume.” Your Sim will then consume the rock in an impressive display of light and power. I don’t know any other way to describe the process. Try it for yourself and see!

Sims 3 Alien Consume Space Rock
An alien consumes a space rock to restore brain power.
Tip: When searching for space rocks in the world, click on a rock and look for an option to “Consume (Provides a Small Amount of Brain Power).” You’ll know this is a space rock before you send your Sim across the world to collect it. If that option does not appear, the rock is not a space rock.

Using Alien Powers

Using your Sim’s alien powers also depletes their brain power. Aliens need to rest and restore brain power after using their powers for too long.

If you’re not careful, an alien can become “mentally ravenous,” which decreases their mood by 50 points until they recover.

Sims 3 Alien Mentally Ravenous
This Sim is mentally ravenous from having her brain power depleted.

Before you do any heavy mental lifting, make sure your Sim’s brain power bar is full. Then, using their powers is as easy as clicking on a Sim or an object, depending on what you’re trying to do. See the sections below for how to use the individual abilities.

Mental Scan

When your alien meets a new Sim they can “Scan” them to find out their traits. Click on a Sim and choose “Scan.” The alien will walk some distance away and use her powers to scan his mind.

The animation for mentally scanning other Sims is the same one used for bio drain and bio boost (see below).

Sims 3 Alien Mental Scan
Learning another Sim’s traits is easy when you’re an alien.

Each scan reveals one trait about the Sim. You’ll have to scan a Sim multiple times to find out everything about them. And the best part is, the Sim doesn’t even seem to know they’re being scanned.

Scanning Objects

Click on your alien Sim and choose “Scan Object.” She’ll go find a random object to “scan” on the lot. In my experience, Sims usually go outside to scan objects. I’ve had my Sim scan trash cans, chairs, grills, tables, and even dirty dishes.

You’ll often see visiting aliens in the neighborhood scanning objects. It’s the same animation playable aliens use.

Sims 3 Alien Scan Objects
An alien scans objects with her data recording device.

While scanning, aliens use some sort of extraterrestrial tablet/scanner to record data about the earthly objects around them. I assume they’re sending this data back to Sixam for analysis.

Transmuting

Transmuting precious metals and gems is another interesting alien power in The Sims 3. After collecting a metal or gem in the world, click on it in the Sim’s inventory and choose “Transmute.”

The Sim will levitate the rock in the air while sending brain waves into it (at least that’s what I imagine they are). After a few minutes of transmuting, you’ll receive a message that your Sim instilled the stone with “much alien love,” increasing its value.

Sims 3 Alien Powers Transmute
An alien transmutes a precious gem to increase its value.

You can transmute the same metal or gem multiple times to increase its value even more.

It’s possible for your Sim to fail at transmuting. If they fail, you’ll receive a message that says, “Transmuting requires great concentration. A good mood can lead to the best results!” Try again when your Sim feels better!

Mind Control

The Mind Control power is only available when your alien Sim is at home and guests are over. Use this power to transform a visiting guest into a servant for two hours. Just click on your target and choose “Mind Control.”

Sims 3 Alien Mind Control
A Sim under mind control cleans the dishes.

The Sim under the alien’s control will perform household chores for the entire two hours. They’ll make beds, do dishes, mop up puddles, clean toilets and sinks, etc. If there are no chores to be done, they’ll just stand around until time is up.

This is a good way to get your house cleaned for free without hiring a maid. Invite over Sims you don’t like very much and put them to work!

Tip: If your alien Sim and the target Sim are sitting down, the mind control option will not be available when you click on the target. They both must be standing for the interaction to work.

Re-combobulation

Aliens can “re-combobulate” broken items around the house. Instead of manually repairing things, they simply “zap” them with their big brain alien powers.

Sims 3 Alien Re-combobulate
An alien re-combobulates a broken TV.

Click on a broken object and choose “Re-combobulate Broken Device.” Your Sim will walk over to the object, put one hand on their head, and outstretch the other hand. Then, they’ll send a beam of power into the object to repair it.

If an alien notices a broken object before you do, they may fix it autonomously. It’s always handy to have an alien around the house!

Bio Drain & Bio Boost

If you click on another Sim with your alien Sim selected, you’ll have a few new options, including bio drain and bio boost.

Choose “Bio Drain” and your alien will literally drain the other Sim’s social, hygiene, and fun motives, transferring them to herself over time. This effect lasts for one hour. During that time, you cannot boost or drain the Sim again.

Sims 3 Alien Bio Drain
It is now my duty to completely drain you.

After being drained, a Sim may get angry and insult the alien who drained them. So be careful with this interaction. My Sim drained her father, which upset him very much and they lost their friendship.

Choose “Bio Boost” and the mechanism is reversed. Your Sim will transfer their motives to the selected Sim over a one-hour period. This refills about one third of the motive bars, just as draining will deplete about one third of the bars.

Bio boost and drain cannot be used on other aliens, only non-alien Sims.

Probing

Probing is more of a short interaction than a power or ability. If you click on a normal Sim and choose “Probe,” the alien pulls out a big, scary looking contraption with a needle on the end. Your Sim will cower in horror at the sight of it.

Sims 3 Alien Probe
The alien probing device looks scarier than it is.

But after a moment, the scary needle disappears and a rubber duck with a feather attached appears instead. The alien uses the feather to tickle the Sim, and they both have a good laugh. Gotcha!

No actually probing takes place. I’m sure someone out there is very disappointed.

UFO (Galaxa Space Car)

Alien Sims have access to the special UFO – also known as the Galaxa Space Car.

There are two ways to get the UFO in The Sims 3. Move an alien into the active household who already has one in their inventory. Or use the buydebug cheat to purchase one from the buy mode catalog.

A Sim pilots a UFO (Galaxa Space Car) in Sunset Valley.

If you meet, befriend, and move in an alien, look in their inventory and you should find the car there. Place it down on a driveway just as you would any other vehicle.

If you’re playing a born-in-game alien and you want them to drive the UFO, you’ll have to cheat to get one. Here’s how:

  1. Hold Ctrl + Shift + C to open the cheat console. Type in “testingcheatsenabled true” without the quotes and press enter.
  2. Type in “buydebug on” without the quotes and press enter.
  3. Open buy mode and click on the question mark box next to the category tabs.
  4. Go to the “Misc. Objects” category and the Galaxa Space car should be near the bottom row. It costs $11,900 – so make sure you have the cash available!
  5. Place it on a driveway and the UFO is all yours!

The space car hovers above the driveway, and doesn’t actually touch the ground. When your Sim drives, they teleport from the sidewalk into the car. Then, they levitate into the sky and dart to the destination in a trail of light.

Tip: Flying a UFO is a much faster form of transportation than taking a normal car or walking. Travel in the space car is nearly instantaneous. I highly recommend obtaining one for all your alien Sims!

Alien Test Subject Career

Alien Sims are eligible for a special career that normal Sim’s can’t apply for – Test Subject. Click on the Science Facility in any world and choose “Get Part-Time Alien Test Subject Job.”

Sims 3 Alien Test Subject Job
Alien Test Subject is a part-time career for aliens only.

Since this is a part-time career, it only has three levels.

Level Job Title Hours Pay
1 Associate Probe Tester 4:00 PM – 7:00 PM $64/Hour
2 Specimen (Living) 4:00 PM – 7:00 PM $84/Hour
3 Organ Farm 4:00 PM – 7:00 PM $114/Hour

Work days are Monday – Friday, with weekends off. Not a bad gig!

What are your favorite alien powers in The Sims 3? I personally love driving the UFO and performing mind control on guests to do all my chores. Re-combobulating broken objects is nice, too. Leave a comment down below and tell us yours!

  1. Wow, thank you so much for this. I don’t think I’ve ever played with aliens in sims 3 (such a pain to wait for an abduction) , but thanks to your guides and especially this one, I will be starting tonight. Sims 3 is such an in-depth game I’m always learning something new.
