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

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

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

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.

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)

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

Hi.
Do you know whether female sims can get prgnant from abductions?
Admin:
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

"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
Admin:
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.

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.
28th April 2013 5:15pm
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.

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

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?
18th November 2012 4:08am
sherry says...
I was having the same problem as you but I read somewhere to sell all the space rocks and look for the bigger space rocks. It seems that they like the bigger space rocks most and your chances for a visit is greater. I did this and I was abducted right away. I had also kept my space rocks inside my house and not by my telescope. I hope this helps you.

I had a alien come and I didn't try but I had lots of playground toys try that

The "search the galaxy " mode wont get tem to you. I hve a lot of "only" alien families and i discovered that the look at the stars option works best though i am not 100% sure :P

Cyn says...
"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."

Does it matter how much time is left on the "Abducted" moodlet before you save? I saved when there was only 30 Sim minutes left. Also, do to reload, can I just go back to the main menu, and then load my family again? Or do I need to close the game entirely? I've tried reloading from the main menu screen five times, and when then didn't get me the Unexpected Weight Gain moodlet, I reloaded the whole game three more times. I still haven't gotten the Weight Gain moodlet. Am I doing something wrong?
Admin:
It worked when I saved with about 5 hours left. I went to the main menu and reloaded my family. Since the percent chance is 33%, some will have better luck than others at getting it to work. It very well may depend upon how much time is left on the Abducted moodlet, I don't know when the game makes the decision.
18th November 2012 6:23am
JJHopps says...
I had mine saved at 3 hours. Kept exiting to main menu. Finally after the 8 th time reentering I got the mood let. So I know that at least by the 3 rd hour you can change the mood let also that you only have to go to main menu.
16th January 2013 9:57pm
LadyEmaleth says...
Did the save/load thing with 50 min left and also worked ;)

Hey if you put the space rock next to your telescope they will come
18th November 2012 10:04am
Elizabeth says...
Saving as soon as my sim was taken aboard the spacecraft, and reloading until I got the unexpected weight gain moodlet did work for me. It did take several attempts. You must wait until the Abducted moodlet goes away. Immediately after that went away, my sim got the unexpected weight gain mood let.
18th November 2012 4:42pm
Faust says...
Same issue as Coady... I keep my sim in the telescope for hours, have several space rocks and high logic skill... But even so, no contact with aliens so far. I've read in another website that you can't get abducted WHILE in the telescope, but you must be doing some other kind of activity outside. Is that true?
18th November 2012 8:32pm
ridiculouslyaddicted says...
I've been abducted multiple times using the telescope. So far it has always been while my sim was using the telescope never while doing other activities.

Well the funniest thing happened to me. My sim was woohooing with his wife, stopped in the middle of it, and ran out there and got abducted.

Atlanta says...
"save before this moodlet wears off and reload until the Unexpected Weight Gain moodlet appears."

Do you mean shut the game down completely or just go back to the main menu?
Admin:
Back to the main menu, other people are having trouble doing this and it may depend how much time is left on the moodlet when you save.

ShaPri says...
Before I start, I just want to compliment you on this guide. I've been using it for the past 2 years and it's very helpful! ^^

Okay, my sim has level 10 logic; she goes outside and uses the telescope every night and has a collection of over 15 space rocks- more than what all sites I've searched have deemed necesary. Am I doing something wrong, becuse I'm not getting visited or abducted :(

I just want to add that I do have seasons installed, and was abducted before (when I had absolutely no idea what was going on).
19th November 2012 5:16am
Anthony8th says...
Whenever i trigger an abduction, they always take the wrong sim :-( ALWAYS. I have one sim get the rocks and use the telescope but they always take his wife, every time. Am I missing something?
19th November 2012 1:08pm
Kate says...
I can't get an option to upgrade my Galaxa Space car. My alien has level 7 handiness, but the option doesn't come up.
Also, I have a male and female human in my house. The male has lots of space rocks and uses the telescope all the time, but he hasn't been abducted yet. My female sim is getting abducted constantly!
Admin:
Ricalynn told me that she observed the Aliens abducting whoever was closest to the Alien's spawn point. As another commenter noted, you might not have luck while the Sim is using the telescope. I had my male Sim stand out in the yard while his wife was working the telescope and it worked on the first night.

yoy gotta place the space ship on a parking lot to be able to upgrade :-)

To upgrade the Galaxa Space Car it must be in a parking space first. Once the car is in the space you should be able to upgrade it.

My sim was upstairs on the treadmill working out while another was at work and the third was on the telescope outside. The sim that was on the treadmill was the one that got pulled by the inspect pretty lights action or whatever it is.

I also have the problem of not being abducted! I have numerous space rocks and add to the collection each day, I have full logic, and use the telescope! What am I doing wrong?
20th November 2012 6:46am
Ally says...
Try and put ALL the space rocks you have beside the telescope, between the hours of 12:00am and 3:00am and have your sim look through it. The first time I did it, it happened almost Immeadiatley but he didn't get pregnant. The second time I did it, it happened just as fast again and he did get pregnant.

Funny thing happened. I received the Weight Gain moodlet, went through all the days, birth happens, but with no baby. The baby didn't come, even though the game prompted me with the keep or return question and the naming part. Did this happen to someone else? The glitches and bugs in this update are driving me up the wall, primarily in my since-the-first-patch save in Sunset Valley, where this bug is irritating me.
