The Sims 4 Mod: Simvestigations
Your Sims can become private investigators in this mod for The Sims 4! What was originally based on the Private Investigator active career from The Sims 3 Ambitions, evolved into its own mini game game. Take cases and look for clues to determine who is innocent, and who is the culprit.
How to Play
The mod adds a new "Simvestigations" app to the phone. Select it and choose "Search for Cases" to find a case to solve. It works similarly to the Odd Jobs system from Island Living. Solving cases increases your star rating, and a higher star rating unlocks more cases that are higher paying but more difficult.
After choosing a case, the game will assign a random Sim as the culprit, and one or more other Sims as decoys (assuming you start a 0 stars, your first case will only have one decoy). Using interactions that are available to your Sim, deduce which Sim is the culprit. There are various ways to find clues, including talking to the suspect, rummaging through their trash, using the Listening Device from StrangerVille, and more. See further down for more information. The mod is more likely to choose Sims with traits, skills or who live in worlds based on the case description.
As your Sim finds information about the case, there is a random chance it will increase your Sim's "Confidence" that the other Sim is the culprit. Once your Sim's Confidence reaches 100%, you can use the phone to report the culprit and complete the case.
Your Sim isn't doing all the work, though. You, the player, have a bit to do as well. While the chance of gaining Confidence is random, it is higher when looking for information on the actual culprit than on a decoy. Therefore, if you notice an unusually high success rate, you may have found the culprit and should continue investigating. Conversely, if you notice a low success rate, maybe you should start investigating a different suspect. Your Sim can only ever get 100% Confidence on the culprit, decoys will cap out.
Ways to Investigate
There are multiple ways you can find information on a suspect:
Become friends with them and convince them to give you information.
Become friends with them and trick them into giving you information.
Be mean to them and demand information.
Secude them for information.
Become friends with a household member and ask for information.
Rummage through their trash.
Research them on a computer.
Hack for information on a computer.
Use the Listening Device from StrangerVille. After using the device to listen in on a suspect, click their recording and select "Use as Case Evidence". This will delete the recording and has a chance to increase your Sim's Confidence.
Analyze previously rummage trash using the Chemical Analyzer from Get to Work.
Side Cases
Aside from the mini game, there are other cases you can take to earn extra money and increase your star rating. These include socializing with other Sims around town for information, exploring hidden areas from packs, and more.
Some side cases require certain packs to function. The mod is split into seperate package files, so you can delete ones for packs you don't have.
