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

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.

For the frustrated ones who have yet to encounter any aliens, this is a surefire way to get an alien in your household using the 'Make me know everyone' cheat:
- Assuming you don't want any of your current sims to actually know everyone, go to Edit Town and add any sim to your household
- Using the newly created sim, select the 'Make me know everyone' cheat at the mailbox (via testingcheatsenabled true)
- Next, scroll along your Friends list and you will spot at least a few aliens. Select an alien from the list and you can Invite Over any desired alien
- After the alien arrives, you can either 1)Shift-click him and Add to current household 2)Have a high relationship with the alien and the 'Ask to move in' option in Friendly interactions will appear
- Remove the sim who 'Knows everyone' if desired
Hope I helped
Thanks for sharing this :)

You probably didn't use the testingcheatsenabled true cheat, because it does work....

Everytime I have activated the cheats, it has worked for me.

Kale says...
then you are doing something different than what I just tried.

Did what the OP said, enable cheats, make trash sim, make me know everyone, yet no aliens show up in the list.

Maybe it takes a few days or something, but right now it looks like the only quick way to get an alien is to pray to the RNG.

You have to do the testingcheatsenabled command in the main menu. That confused me too, when I first tried it.

Thanks, my female sim,Poppy had an alien baby, but now that he is a child, he doesn't have the alien powers. I don't know ifhe will get them when he gets older???
Does he talk like an alien? You won't notice the ability to do most alien things until teenhood.

Coriander says...
Aliens should be like Vampires; They don't get it until their teens.

Also, you could have WooHoo with any sim and an alien for a surefire alien child, getting that alien from your method.

I made a family with a dad and 2 teenagers. He wanted to get into the gardening career, so naturally I had him looking for seeds and found space rocks as well. He analyzed them all, got abducted, but nothing happened. Found some more, then was pregnant the next abduction. The teenage son was also abducted (thankfully not pregnant, that would be awkward to explain.) As he has found bigger and more rare rocks he was abducted and pregnant again. I have yet to have them even use a telescope. I think that a sim is more likely to be abducted if they are outside during the times aliens usually visit. If you get the treasure chest from Shang Simla it's great for storing all the rocks and keeping your sims inventory tidy.

At first read this section - "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. There's an even better way for everyone, even non-Ambitions owenrs to get them:" - almost makes it sound as if non-Ambitions owners can summon down meteors, maybe if you changed it to - However, there's an even better way for everyone, even non-Ambitions owners to get them: - instead? Plus you misspelled owners in the same paragraph at the end there. Other than that, thank you for putting so much time and dedication into these guides to help simmers achieve that which they desire. =3
Thanks for the suggestion, I made it a bit more clear. You're welcome for the guides, I love building this site :)

Good Guide Carl.
I wonder if an alien can become one of the other occult sims btw, such as a mummy, witch, fairy or even a vampire. Their brain powers are by far the most practical of all occult sims, but I guess a alien/fairy or alien/witch can make up for a lot of fun as well.

Do alien ghosts appear in a special green colour for example?
15th November 2012 9:24pm
DaSimsManiac says...
actually i tested it and they can be mixed with sup. naturals like witch, vampire, fairy, mummy, ghost. theonly thing they cant is the alien werewolf. if you try that the alien will just howl and stay the same way all over. (except for the bad behaviour such as the tipical werewolf features :P)

Sami says...
my alien wants to become a fairy as one of her lifetime wants but every time I take her to the edit part and there she is a fairy but when I start back playing her she is not...why is that?
31st October 2013 6:49pm
simsalien says...
my Sims didn't become fairies when I cheated them into one. I adopted a pet that had bad traits and cheated to change its traits. it stayed the same, all you have to do is save and quit a couple of times. It should work eventually.

wow this is really great info thanx for that I will post on my Facebook fan page and later my site when I fix it lol

Just want to say I love your guide it is the best! And I wanted to ask if females can get pregnant from abduction too or just the males?
16th November 2012 7:28am
Shae says...
Do you know whether female sims can get prgnant from abductions?
No, they cannot.
16th November 2012 9:05am
Poppy says...
The alien that abducts them comes down to Earth with them. So, if the alien is a MALE alien, the sims can fall in love, get married, and have kids with them
7th December 2012 6:05pm
Faith says...
Another option is< after activating cheats (testingcheatsenabled true)you can shift click on the alien and click add to active family

"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"

Does this mean your 3rd gen alien won't have alien abilities, since your DNA would be diluted to 25%?

And also, between human male and female alien, who gets pregnant?

As always, Thanks for the great info
That should be correct on the third generation, though I'm not 100% sure.

The female alien would get pregnant. The Aliens woohoo and get pregnant normally, the Abduction is a special case.

betch says...
Can you have a male alien and male human woohoo baby?
31st March 2013 9:59pm
naneninuno says...
I just found out that %50 is not the minimum for alien powers. 25% seems to be the threshold meaning, the offspring of a halfie and another sim containing any % of alien DNA will have alien powers.

invock says...
Interesting fact : if an alien appearing in game is modified with CAS (via mods or cheat codes), it will be categorized as being "Human".
There is no "Alien" category, as there are for ghosts, vampires, genies or simbots for example.
16th November 2012 4:09pm
JK3 says...
It seems like the save and reload if you don't get pregnant doesn't work done it 5 times now ill re-post when i get to 10
17th November 2012 12:29pm
Coady says...
I have done every single thing you suggested for 15 sims days in a row and cannot get abducted! What am I doing wrong? I find two space rocks a day, and stargaze/search galaxy all night long. Why aren't they coming to abduct me?
