15 Best Sims 4 Alien CC & Mods

The truth is that we may already be living in an alien colony, and they have no idea we exist. What would you do if you found out that was the case? Would you freak out? Hide out in the woods? Or would you totally chill, because man, there’s a lot of cool aliens to meet!

Build your own alien and create a new storyline for your Sims with these free downloadable packs! Sims 4 is compatible with a huge range of add-ons, and it’s easy to find ones that match the aesthetics you’re after. Check out our favourites, or learn more by reading our post on the ten best Sims 4 packs CC.

1/15. Sims 4 Suit Pastel Alien

This is a Pastel Alien Suit for your humanoid robot. It may not be originally designed for aliens, but it’s definitely fit for the job — and its bold colors will help your robo-humanoid make friends wherever it goes. Add a bit of flair with some killer boots, or maybe mix and match with another outfit from this collection! What do you have to lose?

2/15. Sims 4 Lip’s 153

Your Sim thinks they might be an alien — but will they ever find out for sure? One thing’s for certain, though: aliens love lipstick. And coloring their lips with a spectrum of colors couldn’t make them happier. Taty’s ‘Infinite Universe’ lip palette is packed with pigmented shades that will make your Sim look extra ethereal.

3/15. Sims 4 Star Skin

Just as the Na’vi in Avatar are the most stunning and gorgeous aliens seen on screen, the aliens in Star Trek are easily the most horrifying. The parasitic nature of their biology, for example, means that they’re not exactly friendly or easy on the eyes. But compared to the worm creatures from The Thing, even these guys look like a bunch of friendly fuzzy bunnies.

4/15. Sims 4 Set of Cyborg

The robots will not take over the world — at least, not today. But they might well be taking over our computer screens, thanks to a new bundle of Sims-y CC from TSR. If you’re looking to create your own humanoid automata, this latest batch of sinister eyes and metal masks will help you create cyborgs, Terminators and other Robo-Riffs on the human form that we mere humans can’t quite achieve.

5/15. Sims 4 Makeup for Cyber Girl

I know: it’s hard to admit that you like Iron Man. But think about the kind of person you are: You’re intelligent and empathetic. You want your technology to be savvy and high-tech, but also holistically cool. And Tony Stark is right there with you.

6/15. Sims 4 Pack of Stellar Stuff

The Stellar Stuff Pack is the most out-of-this-world collection of clothing and décor that we have ever released. With 10 creators contributing fantastic items, this pack is literally out of this world! You can create anything from your own stellar space-themed home to memorializing your favourite fictional astronauts with a rocket-ready tribute.

7/15. Sims 4 Accessory for Third Eye

Human third eyes are supposed to be a sign of psychic abilities. But what if aliens had them too? They probably didn’t use their psychic powers for benevolence, though — I’d guess that their third eyes were actually laser-shooting death rays! As my grandmother used to say, “the eyes are the window to the soul.” So naturally, you can add a 3rd Eye accessory your Sim’s face. It looks pretty cool too!

8/15. Sims 4 Dangly Antennae

Your Sim is an insect-alien. Alien ant antennae have become a reality! The development of these science fiction-like appendages, which could be used to sense surroundings and even communicate telepathically, could be the first step in making DeBlaere’s future of ‘alien androids’ a reality.

9/15. Sims 4 Alien’s Crown

Aliens! I don’t know about you, but they’re no stranger to me. In fact, I have an alien right here in my Sims 3 game that’s been waiting for an heir to the throne since I first took control of the planet. And it is Now. Time. To. Pass. The torch.

10/15. Sims 4 Outfit for Space Invaders

Space Invaders! Put on this outfit, grab your jetpack and head to Sixam, the newest planet in No Man’s Sky. Because no matter how far you travel, there’s nothing sweeter than a fresh new suit.

11/15. Sims 4 Mod for Enhanced Aliens

Your favourite Sims game is about to be taken to a whole new level. This update will introduce hundreds of alien powers for all your sims — from boosting their needs, to forcing them to clean their house or repair broken objects. And you can use these powers for good and evil — all depends on how you use them!

12/15. Sims 4 Hotspot UFO

Aliens, UFOs, extraterrestrial life — whatever you call them, they exist. So why not embrace this fact? With the UFO Hotspot mod, your Sims are more likely to be abducted by aliens at parties. If you’d like to give your Sim a different type of close encounter, try one of the many other mods available on the SimCity Social forums!

13/15. Sims 4 Headpiece Overwatch Conversions

It’s pretty understandable that these aliens may not be able to do much but run around and attack you. However, I personally feel like they should at least have a unique way to play the game: what if some of them could fly, others could dig through walls, or even burrow themselves into soil? That would make them much more interesting and an overall fun addition to the game.

14/15. Sims 4 Skin Recolor Haunted

Want to make your Sim stand out among the Marvel cast? We’ve got you covered. Your alien’s skin color will gleam like a lava lamp, meaning you can finally say goodbye to those boring gray-green and pale blue designs from Guardians of the Galaxy. If you haven’t had your fill of blue aliens, we also offer a sapphire option that looks kind of like Abigail Brand from S.H.I.E.

15/15. Sims 4 Alien Holo Eyes

If you ever catch the sparkle in an alien’s eye, then you best watch out — literally. Just look at this Holo Alien Eyes by Pseudosim, which have beautifully captured the magic and beauty of space. If a person can fall into the black hole of UFO culture, what’s to say they can’t get lost in these gorgeous eyes? They’re simply out-of-this-world.
