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.

Can a male sim Woo-Hoo with a male alien to become pregnant?

No, male sims can only become pregnant in The Sims 3 through Alien Abduction.

So, fairies and other occult states (werewolves, vamps, witches etc) can't be impregnated by abduction.. but can a male mermaid? Are they considered occult or is that more a genetic coding?
12th April 2018 12:30am
A random guy willing to help says...
Any life state added by any expansion including mermaids, plantsims, zombies, pets, plumbots, simbots and mummies are considered to be occult, so none of them will be able to be more than one occult type. If you want mixed occults, then you need to install the following mods:

Nraas Master Controler
Nraas Hybrid

You can find instructions for both on their site. If you can't find instructions for making hybrid sims anywhere online, then head over to Mod The Sims site in the discussions sections and ask @igazor for help.

So I currently have an elderly male Sim who's maxed out on his life span, as in he is at the end of the bar and I'm just waiting for him to die. He was abducted twice with me doing nothing special; now he's Alien pregnant and I'm flabbergasted!

I have been waiting for aliens to visit me and with about 15 space rocks in my garden they still didnt come, I read on here that you have to put the rocks around the telescope and I did that and the first night I got an alien visit and two nights later another one. Dont know if its a coincidence or not but definitely worth a try if you havnt had a visit yet :) this really is an amazing site

Blossom says...
My female sim had been abducted several times, but never my male sim. When I decided I wanted an alien baby and couldn't get him abducted I tried these methods.

1. Place the space rocks around the telescope.
2. Put the telescope on the ground, not the roof or a balcony.
3. Clear space on the lot, so there is room for the alien ship to fit.

If none of those work, move your family to a new town. (I just copied my lot to the clipboard and placed it in an edited, but unplayed, version of Midnight Hollow).

My household was visited by aliens on the first night, and my male sim was abducted on the second night. I think if you've gotten too far into the game (I was at week 7) all the aliens die of old age and you can't be abducted anymore.

You have to click on the spaceship to upgrade it. It has to be in a parking spot and you have to have high enough handiness skill.

Can an alien drink a life-state elixir/eat a fruit of life/sleep in a sarcophagus in order to change their life state? Will drinking a potent cure remove "alienism"? Will drinking one while under another life state convert them back to Alien?

Callum says...
What I did was get my sim to collect as many rocks he could find. He got about 30. I think the price also varies your chances of an abduction. Keep a mixture of big and small ones, expensive ones and cheap ones in your inventory AND in your garden. Learn at least 3 logic skill (worked for me) Then between 12am - 3am have your sim stargaze. I almost immediately got abducted. Your sim should stop doing whatever they are doing and run to some strange lights and 'investigate strange anomaly' Then they will be sucked up into spaceship. You get them back after about 30 seconds. I didn't get pregnant first time, but I did second time. :) Hope I helped.

Oh my Plumbob! I play the sims 3 for years. The seasons pack since it came out... Trying to get my male sim pregnant, only female sims get abducted. Started a random lagacy with my male sim as a freelance scientist. Get abducted on the second day. (forgot about that completely) ant the ONE time i DONT want a pregnentcy... You guessed it... Well never played with a alien sim.. Could be Interesting
12th May 2018 3:06pm
hi says...
i don't like the idea that my male sim would get pregnant, or my female sim. they are practically engage. it might be great for others, but not for my main sim players. i used cheat mods to control the other households, right now my sim is being abducted, and i have no way of cancelling it. something always happens to her... the good thing about it, i always make sure i save. so i might restart the game. i don't like the idea that my main sims to have kids, nor send them back in their planet if just in case there is one. would just ruined the game for me. stop illuminatieng my game

How do u upgrade ur space ship

My male sim is pregnant from an alien but I really , REALLY dont want him to be. I could reset from the last save, but I was wondering if using an NRaas mod I could end the pregnancy? I cant remember which one but I have ended pregnancies on the sims before using that mod, so do you think it would work with an alien pregnancy?
14th August 2015 8:35am
DemonChild says...
I know it's been a few years but for future advice if u really don't want the baby u can send it back to it's home planet and then ur sim can go on living his life like nothing happened

I am trying to figure out the list of alien gem transmutes. Nothing turns into Lapis, nothing turns into Luminorius Gems.

Here's the list from bottom (as transmuting makes them worth more) to top:
Quartz
Blue Topaz
Amethyst
Smoky Quartz
Emerald
Ruby
Citrine
Alabaster
Yellow Sapphire
Turquoise
Smithsonite
Tanzanite
Bloodstone
Geode
Tiberium
Diamond
Jade
Septarian Nodule
Vampire Eye
Fluorite
Opal
Rainbow Gem
Sunstone
Moonstone
Pink Diamond
Soulpeace.

Lapis will turn into Ruby, Luminorius Gem will turn into Vampire Eye. But can't make anything lower turn into them.

By the way, easy to get rich, use gatherer trait, pick up raw palladium, smelt it, transmute it to Titanium, smelt, transmute to Woohooium, smelt, transmute to Compendium, smelt, transmute to Mummitomium, smelt, transmute to Plutonium, smelt.

All smelts must be done with the gatherer trait. End plutonium worth around 80 million, perfect for being rich without blowing the bank. No world adventures needed.

Nancy
27th September 2018 8:03pm
Nancy says...
Now for the metals, they go from cheapest to highest, no weird gaps like the gems.

If you bump an ingot to the next type, it will be an ore, which is of course the guide to getting rich. I start with a gatherer smelted palladium for that, after the max 5 transmutes you have a mega expensive plutonium.

Here's the order from low to high they bump up to (of course sometimes the values just increase).

Iron
Copper
Silver
Tungsten Carbide
Gold
Iridium
Carbon Steel
Platinum
Mercury
Palladium
Titanium
Woohooium
Compendium
Mummitomium
Plutonium
Supernovium

I also find that the alien can transmute 2 items, then eat a large space rock.

An alien visited my house at 10 pm. It also makes a curious sound when she/he arrives. And another thing I noticed, is that (Well, or almost on the alien that landed on my house) they're rude. The alien landed on my house, and when I went to say him hello, he insulted me. Am I the only one with this? I didn't got abduced. The 2nd night, A alien visited me. Oh and, awesome post!

Amelia says...
In my current game, none of my sims have any logic skill, they've all stayed inside during the night, female witch, male human, my witch has been abducted twice, both times she was inside.
my male Sim has just been abducted, like 1 Sim day ago, (Actually just now, because I paused my game to write this,) he has no logic skill, he has full skill in handiness, painting, inventing and mixology, he is pregnant.

when they were abducted, both Sims were inside the house. has anybody had this happen to them?

My ageing is off, they've both completed their LTW (Males was renaissance Sim, females was culinary librarian.) I now have pups and an alien on the way.

p.s will this complete his wish to 'have first child'?

Philik says...
I don't get it, my sim has 3 GIGANTIC space rocks 5 BIG space and 6 SMALL space rocks. He looks through his telescope EVERY NIGHT and he has NEVER gotten abducted by ALIENS!!! What do I do? I want him to end up pregnant.
Admin:
Are you placing the space rocks on the ground?   Have aliens visited the house but not abducted you?  Also make sure to search the galaxy every now and then and not just stargaze.  

I had someone picking up at least one space rock a day while someone else searched the galaxy and it seemed to get me abducted several times.

omg female teen sim got abducted by aliens what will happen????
Admin:
She will come back to the house with a moodlet then she can carry on with her life.

Females do not get pregnant from alien abductions and teens cannot get pregnant unless you use mods.

Yes all female sims younger than Elder can get pregnant with an alien through the normal Try For Baby interaction. Female sims however, can not get pregnant from an alien abduction.

Hi Carl,
You mentioned in your guide that female Sims can't get abducted, and that when male Sims are abducted, they are pregnant with an Alien Baby. But my Sim is the only female (and only Sim) in her household and she was abducted by a female Alien. Was it some sort of glitch??

I know it's been a few years, but he said "Nothing too bad will happen to a female Sim, although a male has a 33% chance to have the pregnant ", not that the females can't get abducted

My male sim was abducted, but it's my female sim (his girlfriend) that does all of the collecting. Any who, he got abducted, had the unexpected weight gain, then had the baby. I said to keep it, named it and chose the other trait (it came with artistic so I just left it) and the extra square for a sim showed up, but there's no picture. I've tried to locate it by right clicking the empty box, I've even tried doing resetsim a few times. Saving and going back to it, the picture has the baby in the "Family portrait" in the pick a family screen, but his square is not there anymore, he just ninja vanished on me.
