The Sims 4 Strangerville Mystery Aspiration
If you want to be an investigator, play through the sims 4 Strangerville mystery aspiration!
The Sims 4: Strangerville is a weird pack that has a whole investigator storyline that you play through this aspiration.
You’ll need to discover the source of an infection and help vaccinate sims to save the world!
Home Turf Bonus Trait
The home turf bonus trait is given to any sim that starts their life with a location aspiration like this one. This trait makes sims enjoy being in their home neighbourhood more and gives positive moodlets.
This aspiration has your sim needing to go all around Strangerville, not just stay in one area, so you won’t see the effects all the time but it can still be helpful to keep them happier when they aren’t possessed.
Best Traits for The Sims 4 Strangerville Mystery Aspiration
Strangerville mystery is an interesting aspiration choice for you and it’s hard to pick specific traits that may be helpful. These are some that I find can help with the socializing aspect that you need to recruit sims:
- Outgoing: Sims who are outgoing enjoy socializing with other sims more than those without it.
- Cheerful: A sim with the cheerful trait is going to get happy moodlets more often which can push you through the aspiration faster.
Stages of the Aspiration
There are four stages of the sims 4 Strangerville mystery aspiration to play through. Each stage takes you through specific parts of the story and will lead into the next in a fun way!
Stage One: New Resident
- Talk About Strangerville With 5 Sims
The first task for this aspiration is to talk about Strangerville with 5 sims. You can do this by clicking on any sim that is in Strangerville and choosing the talk about Strangerville interaction.
When you do this you’ll get some information through notifications giving you important things to know about the secret lab and the infection.
- Buy Curio from the Curio Shop
Your next task is to purchase something from the Curio Shop. You can see the shop on the map in front of the trailer lot and the broken airplane lot. You can travel to any lots in the main area of Strangerville to head to this location.
Once there you’ll click on the shop and choose buy curio items! You’ll want to purchase some listening bugs for sure, or just any other items you like.
- Examine Sealed Door at Secret Lab
The last task for this first stage is to examine the sealed door at the secret lab. You’ll find this location inside the crater at the top of the map, head there.
Once at the secret lab, find this large locked door on the first floor and click on it and choose examine. That will satisfy the need!
Stage Two: Personal Spy
- Gather 15 Pieces of Evidence
Your sim needs to compile a secret dossier so they can get a keycard for that sealed door. So, you need evidence. You can search around the secret lab in items that are flashing bright red and click and search for evidence but this won’t be enough. There are some other ways to gather evidence too!
Your next option is to head to the library lot in Strangerville and click on a bookcase and choose Search StrangerVille Archives.
Your next option for getting evidence is to chat with scientists. You’ll need to build a relationship with them first, so do some friendly interactions until the Request Evidence from Secret Lab option is unlocked.
When you do these interactions you’ll get stuff like aerial surveillance photos, redacted documents and more. You’ll see them in a stack in your sim’s inventory.
Your next option is to plant bugs on important people like scientists and military personnel. You’ll first need to have a 51M5 Spy Bug, you can purchase these from the Curio Shop!
Once you have a bug in your inventory you can click on important sims and choose plant bug. Your sim will hug them and hopefully they won’t catch you.
Once you have bugs planted you can use a listening device and choose listen in on and you may get some evidence from that too!
- Compile a Strangerville Secret Dossier
Once you have 15 pieces of evidence you can click on it in your sim’s inventory and choose compile secret dossier. This is what you’ll use to get someone to give you a keycard!
- Open the Sealed Door in the Secret Lab
There are two ways you can get a keycard to open the door in the secret lab. The first way requires you to be in level 5 of the military career, so if you don’t want to work through a career, go to the next part. To do this you can go to a computer and choose requisition keycard and you’ll trade your secret dossier for a keycard.
The other option is to get one from a scientist. You’ll need to have a completed secret dossier to trade with them and a good relationship with that scientist. You’ll find a request keycard option and when it works you’ll get the keycard in your sim’s inventory.
You’ll then want to head to the secret lab and open the door so you can traverse deeper into the secret lab.
Stage Three: Pathogenic Investigator
- Collect 15 Spore Clusters
Your next task is to collect spore clusters. You’ll first need to get an infection scanner. You’ll want to head over to the bar in StrangerVille and chat with military personnel.
You’ll want to question them about the spores in the lab and you’ll get a notification telling you about a scanner they have. You will want to have a good relationship when you do this.
Then, you have some options on how to get it. Each option is a completely different category of skill or thing your sim should have. The easiest way is to just bribe them and pay for it.
- Seduce for Infection Scanner (Flirting)
- Pull Rank for Infection Scanner (Military Career)
- Bribe for Scanner (§750)
- Impress for Infection Scanner (Charisma Skill)
- Fight for Infection Scanner (Fitness Skill)
Whatever you choose, you’ll get the scanner in your sim’s inventory and now you should head to the secret lab.
At the secret lab you can click on the ground and choose to scan here. Your sim will use the scanner and five spores will appear on the ground and you’ll click on them to put them in your sim’s inventory.
You’ll need to do this multiple times, you just move around the outside of the secret lab to do this and get 15 total clusters in your sim’s inventory.
- Assemble the Hazmat Suit
There are two parts to a hazmat suit, a spore filter and an incomplete hazmat suit. To get the spore filter you need to first head to the secret lab.
Now that you have 15 spore clusters you’ll want to go through the door in the secret lab to the first level of the basement and find the machine that’s blinking red. You’ll click this and choose construct infection profile data.
You’ll get the data in your inventory and you’ll want to head to the library to give it to a scientist for a spore filter.
You’ll find a scientist (you must have a good relationship) and click ask to craft spore filter.
If successful you’ll get a notification telling you that the spore filter will be in the mail soon. You can head home and you’ll get it in the mail the next morning.
To get the incomplete hazmat suit you’ll want to head to the curio shop and use the question about spores in lab interaction. Then, you’ll get a notification telling you about their secret inventory and you can purchase the other part of the suit for 1,000 simoleons.
Once you get the spore filter in the mail you ‘ll have both in your inventory and its time to assemble.
You can click on either piece and choose to combine to get a hazmat suit!
- Traverse to the Deepest Part of the Secret Lab
Before you do this, wear your hazmat suit! If you don’t your sim may get temporarily possessed by the infection. Click on the suit in your sim’s inventory and choose wear hazmat suit.
You’ll then want to use your keycard to open doors until you reach the very bottom, then open the final door with a keycard to get into the room where the mother plant is!
Stage Four: Strangerville Hero
- Vaccinate 3 Sims
To create vaccines your sim needs to collect 5 spores and 1 bizarre fruit for each vaccine. So, you’ll need 15 spores and 3 fruits total. We’ve already discussed how you can get spores with the infection scanner, so go back to the lab and scan the ground.
To get bizarre fruit you need to go the secret lab and nurture the weird plants that are all around. When you do this the plants open up and you can click on them and choose harvest bizarre fruit. Do this to three different plants!
Once you have the spores and bizarre fruit you’ll go down a level in the secret lab and click on the same machine from before and choose create experimental vaccine. When you make one it will appear in your sim’s inventory. Make three of these!
Once you have all 3 you’ll want to go to the town center and find three different possessed sims and click on them and choose test experimental vaccine.
Your sim will throw it in their face and after the third one you’ll get a notification telling you that you can now create the official vaccine!
- Recruit 3 Sims to Help Stop the Source of the Infection
To be able to recruit sims you’ll need to vaccinate them first, so you’ll need to create three doses of the infection vaccine. You’ll make this the exact same way as the experimental vaccine so you need 5 spores and 1 bizarre fruit!
Then you’ll need to get some sims to join you by finding sims you have a good relationship with. You’ll want to invite them to the secret lab and click on them and choose administer infection vaccine. This is the only way to get the option to recruit because sims need to be protected before they can join you.
Then, once the sim is vaccinated you can click on them and choose recruit to fight mother plant and you’ll get a notification telling you if they’ve joined your team.
Repeat this process 3 times until your team is complete!
- Defeat the Source of the Infection
The final task to complete the Sims 4 Strangerville Mystery Aspiration is to defeat the mother plant. Now that you have your team you’ll want to get them to come with you to the bottom of the secret lab to fight the mother plant. Use the travel here together option when you click on the ground to get them to move.
You’ll need to unlock the doors with your keycard until you get into the room with the mother plant. Then click on the plant and choose fight mother plant with and pick your helpers.
Once the fight starts you’ll see the health of your team and the mother plant in the left top corner. You can click on the plant at any time during the fight to change tactics, I find it best to just throw vaccines and charge over and over and get it done quick before you can be attacked.
If you win the mother plant will spew out some gross green stuff and then die, yay! You can always click on them to revive it and bring back the infection.
Hero of Strangerville Reward Trait
When a sim can finish the sims 4 strangerville mystery aspiration they are going to be given the hero of strangerville reward trait.
This trait’s description reads “As the hero of strangerville you will receive fan mail as well as being able to retell the tale of how you defeated the source of the infection.”
