Aliens are a new type of non-Human Sim available in The Sims 3 Seasons. These extraterrestrials visit the neighborhood to learn about Sims on Earth and may even abduct them and perform experiments. This guide will teach you how to get an Alien, Alien babies and Male Sim pregnancy, and the special abilities Aliens get in The Sims 3.

Finding Aliens

How to Get an Alien to Visit
Aliens have a chance to visit each night between 12am and 3am. A visit lasts only an hour and a half to two hours. Visits are distinct from abductions and allow your Sim to socialize, possibly befriend, and even ask an Alien to move in with them.

The base chance of a visit is 5%. Collect space rocks and store them on your lot. Once you've got five, aliens have a +15% additional chance to come to your lot. Once you've made friends with one, there will be an even greater chance of visits. If an Alien doesn't visit your home lot, there's a 20% chance each night they'll appear somewhere around the neighborhood and leave behind a few space rocks. When you've met an Alien, you can invite them over using the phone, so making friends with them is easy.

Alien visitors once befriended may be asked to move into your household. They always start with level 10 logic and level 7 handiness. This will give you permanent control over the Alien, along with their Galaxa Space Car.

An Alien Abducts a Sim

Alien Abductions
Aliens are more likely to abduct a Sim than to visit, simply because of the powerful effect collecting space rocks has on this. To trigger an abduction on your home lot, having a Sim use a telescope is a good place to start. The base chance of an abduction is only 2%, but using a telescope that day adds a +13% chance they'll visit on a given night. Collecting up to two space rocks will each add a 37.5% chance to the visit for a whopping 90% chance of a visit. This seems to reset so that you don't always find your Sims getting abducted, giving you a little bit of control over how often it happens.

When a Sim is abducted, they'll have a bad Abducted moodlet for about twelve hours. Nothing too bad will happen to a female Sim, although a male has a 33% chance to have the pregnant (Unexpected Weight Gain) moodlet when the Abducted moodlet wears off. If you want to ensure your abduction results in pregnancy, save before this moodlet wears off and reload until the Unexpected Weight Gain moodlet appears.

Alien Babies and DNA

Male Pregnancy and Alien Babies
After a male Sim has been abducted and has later had the Unexpected Weight Gain moodlet appear, you know he is pregnant. The Sim will put on weight quickly as the baby grows, and birth will occur 48 hours later. You'll be asked if you want to keep the Alien Baby or send it back to its Homeworld. The choice is yours. If you keep the baby, you'll get to pick the traits. Raising an Alien baby is no different than a normal one.

Alien Pregnancy & Passing DNA
Of course, the Abduction pregnancy is not the only way to get a Sim with Alien powers in your household. Human Sims and Aliens can Woohoo and make babies. So long as the baby's DNA is at least 50% Alien, they will have access to alien telepathy powers and use the Brain Power motive instead of Energy. Supernaturals like Fairies and Werewolves can reproduce with Aliens, and may appear quite interesting (having mixed features of the parents), but the occult DNA will make the Alien powers unusable.

Alien Powers and Features

The Sims 3 Seasons' Alien Galaxa Space Car
An Alien Pilots a Galaxa Space Car

Alien Ship: The Galaxa Space Car
Aliens you invite to move in will come with their ship in their inventory. This is the fastest way to get around, as it can warp from one location to another in the blink of an eye. These can be upgraded with one of two upgrades, each requiring level 7 Handiness (which your Alien has). You can outfit them with laser cannons, which will let them use the craft to invade a lot of your choice. This is just for fun, and the user will indeed get a good moodlet out of it - that is, while the targets on the ground have their clothing singed off.

The Other upgrade seems silly - Space Travel. Can't it already do that given it's in your neighborhood? Oh well. Either way, outitting the spacecraft with this upgrade will allow the Sim to visit one of three places: The Moon, The Asteroid Belt, or The Planet Sixon to go on Rabbit-hole style text adventures which can reward valuable metals, gems, and a wide variety of items.

You can buy the Galaxa Space Car using the buydebug cheat.

Alien Brain Power
Aliens use Brain Power instead of the energy motive. They get to use Restore Brain Power (click the Alien) to restore this, much like meditation. They can fill their bar in 5 hours. They won't get a well rested moodlet, so popping into a bed for a few minutes can give them that mood boost. They'll also restore energy by consuming Space Rocks. The bigger the rock, the more power restored. The drawback to recovering their energy so quickly is that it's used to fuel their special abilities. They have one more major trick though, which can be used to help themselves or others:

Bio Boost and Bio Drain
Using Bio Drain on a Sim will sap his or her Social, Hygiene, and Fun motives and transfer them to the Alien over one hour. This refills about a third of each of these bars. The Alien could even use Restore Brain power or eat a meal after doing this to have four motives moving upward at once. The Alien may be giving, and use Bio Boost on a Sim to do the opposite and channel their needs to aid the target Sim in recovering theirs. Bio Boost and Drain can't be used on other Aliens.

An Alien transmutes a gem in The Sims 3 Seasons
An Alien Using the Transmute Brain Power

Transmute Object
Aliens can transmute Gems and Metals to make them higher value, or bump them up to the next most expensive item of that type. This is much more orderly than the Witch's transmutation. The odds of an item failing to transmute is determined by the value. An item under 100 Simoleons only has a 5% chance of failure, while any over 500 will fail 30% of the time. The mood of the Alien using this helps or hinders as well.

Forum member LordHellscream contributed a tip to making loads of cash with Seasons' Alien Transmute if you also have World Adventures installed. Learn how to use transfiguration to get filthy rich.

Repair Broken Objects
Aliens don't need the Handiness skill to repair broken household appliances and plumbing, they can do so with their minds. Quickly.

Scan and Probe Sims
Aliens can pull a joke on other Sims by whipping out the Probe, which will give them a scare before they hopefully laugh in relief. Their more useful ability is to Scan - which consumes brain power but will teach you one of the target Sim's traits.

Summon Meteor
This requires The Sims 3 Ambitions Expansion Pack. Using a lot of Brain Power, an Alien can call down a meteor strike onto an area. This works just like the random meteors that may strike with Ambitions installed, only the Alien knows it's coming and can stand back and observe. This is a good source of Space Rocks for recovering Brain Power, and occasionally as a particularly catastrophic way to make money. People who don't have Ambitions can collect space rocks from the world and use the Steal Space Rocks option below.

Steal Space Rocks
Clicking the Science Lab between 8pm and 6am with an Alien Sim will allow them to go in and steal four Space Rocks. There's about a 60% chance they're tiny, 25% large, and 15% gigantic. This never seems to fail and is a neverending supply of cash for Aliens.

Sell Alien Secrets
At the Military Base in town, your Alien can sell what they know to betray their kind but profit nicely in the process. This can be done every 36 hours and will get you between 1500 and 2000 Simoleons. The interaction is available between 6am and 8pm.

Part-Time Career: Alien Test Subject
A new Part-time career exists only for Aliens. You can sign up at the Science Lab in town. There are three levels here, with mood being the only metric. All work M-F from 4-7PM. Associate Probe Testers make $64/hour, Specimen (Living) makes $84, and Organ Farms make $114 an hour. There's a 20% chance your Alien will be nauseous after work from all the strange experiments. Overall, stealing samples is more profitable than these jobs.

Wait-- I reset him and he stopped being abducted. Now to Object>Delete the aliens as I usually do when they visit.
4th August 2018 10:38pm
Playalot says...
I wouldn't delete sims from your game as this can cause errors. Deleted sims are still thought of as present by the game mechanics and as you can imagine, that can lead to problems! Deleting any sim in that manner simply puts the sim into hibernation.

So they are de-instantiated and stored out-of-world until needed again.

The game can and usually will auto recover those missing sims, placing them back on their home lots.

If the male sim gets pregnant and keeps the alien baby, and then the baby has a child with another sim when its older, will the child have alien powers?
Admin:
There is a possibility that that child will have alien powers as long as they aren't a different type of occult.

Guys I'm desperate I've tried everything, do you know how I can cheat an alien appearing?
Admin:
Without cheats just colelct a lot of space rocks, place them in your garden, place a telescope in your garden and use it ant night. As long as you ahve Seasons installed, you'll have an alien abduction within a few nights.

Supernaturals can not get pregnant from an Alien Abduction. If you want to experience that game play you will have to play an ordinary male sim.

Liz says...
I have tried to get abducted every night. During the day, I go out to collect space rocks and when I come back I place the space rocks on my lot and analyze them. When it is about ten o'clock, I begin to "explore the galaxy" through the telescope. Then at about midnight I stargaze until five in the morning. I also have planted a garden. I have been doing this for the past 40 sim days. Am I doing this correctly?
5th July 2014 5:22pm
Playalot says...
You are doing things that increase the likelihood of an abduction. Try saving and quitting then clearing out your cache files and restarting your game. Sometimes a restart helps. https://www.carls-sims-3-guide.com/technicalhelp/slowgame.php

When the abduction moodlet wears off, does the unexpected weight gain come right away, or does it take some time? If it takes time, how long would the usual amount be?

So it's been a few years but if you're still curious it happens right away

25th March 2018 10:50pm

I've not seen this before perhaps she is too close to becoming an elder. Have you tried relaxing on a bed together and seeing if the option appears?

Karly Logan says...
I have 20+ space rocks on the lot, I've been trying for an abduction or even a visit since my first sim, I'd have him outside every night and eventually had him start a family. One night his oldest son was staying up late doing homework and got abducted. Now it's that same son and his younger teen brother I. The house, I have the adult boy out every single night while the teen sleeps and NOTHING. Even hadthe teen know everyone and met 6 aliens but the adult sim is only attracted to males and I want an alien pregnancy. As soon as the teen was going to be an adult my whole computer crashed. A girl just can't have her alien baby :'(

I’ve been trying to get my male sim pregnant. I’ve saved the game before the moodlet wore off. I’m having a hard time understanding what they mean by “reload until the pregnancy mood icon pops up.” Wdym? Like save and quit the game until the icon shows?
23rd September 2020 12:05am
Playalot says...
If you save your game after being abducted then let it play until the abducted moodlet wears out..if it becomes the Unexpected Weight Gain moodlet then you know your Sim is pregnant so just keep playing as normal. If the abducted moodlet simply ends then quit without saving and reload your game and let it play out again. This way you don't have to wait to be abducted again..you can simply game-hack the mechanics until your Sim is pregnant.

I find it easier to just level up Logical skill, use the telescope and have space rocks on your lot, without fail my sim gets abducted and if you have enough room in your household and your sim is a normal non-occult sim then it normally results in a pregnancy first time. It also helps to befriend any visiting aliens so try to watch out for them at your Sims door late at night.

Gunther says...
My sim got abducted twice while in dystopia without the telescope. He got pregnant the first time. And then the next day same thing happened. FYI if you designed a skinny muscular male sim and they are pregnant with the baby. They look better with the weight gain.

31st December 2013 8:59pm
Playalot says...
No your sim won't get pregnant if that si what you are asking, only non-supernatural male sims YA, Adult or Elder can get pregnant from an Alien Abduction. She will get a moodlet though that will wear off over time.

When you said "When a Sim is abducted, they'll have a bad Abducted moodlet for about twelve hours. Nothing too bad will happen to a female Sim, although a male has a 33% chance to have the pregnant (Unexpected Weight Gain) moodlet when the Abducted moodlet wears off. If you want to ensure your abduction results in pregnancy, save before this moodlet wears off and reload until the Unexpected Weight Gain moodlet appears." I did not quite understand can you help me like explain in further depth.
27th December 2013 7:08pm
Azalea says...
What they mean, is if a female sim is anducted it has no long term effects, whereas if a male sim is there is a 33% chance he may get the moodlet unexpected weight gain when the abduction moodlet wears off. The unexpected weight gain is actually the sim being pregnant.
Does this help?

Alright. Let me get this straight.
My sim is sleeping and I see the sparkles that are meant to appear when an Alien comes. Now what do I do to get abducted? Walk right up to it?
22nd December 2013 2:47am
Playalot says...
Alien sims will visit your sims world in their space ships so you will sometimes hear and see them (sparkles)as they land their spaceship and wander around often visiting a lot and knocking on a door.
An abduction is different, the spaceship won't land and the sparkles are a beam that your sim will automatically walk/run to and get transported upwards. You can't direct your sim to get abducted, it is an automated animation that will just happen.

No, but you can pause your game and reset your sim if an abduction begins.
