Installation guide

Note: With the public version you can play only over LAN and the launcher requires no login!

Supported versions:
  • Versions 0.6.1 and later only work with The Sims 4 v1.68.154.1020 or later patches
  • Versions 0.2.1 and later only work with The Sims 4 v1.54.120.1020 or later patches
  • Version 0.2.0 only works with The Sims 4 versions BEFORE v1.54.120.1020 (08/2019) patch

With The Sims 4 Multiplayer Mod, you can play The Sims 4 real-time over the network and “live together” with other players in the same household. See what the others are doing, interact with them, and have fun together!

What does this mod do?
  • This mod allows multiple players to play together with the same save file at the same time over the local network. It's a full script mod packaged with a server application that should be run on one of the PCs participating in the game.

Conflicts
  • There are currently no known conflicts with other mods. (It might conflict with other full script mods though.) Important thing is to have all players the same set of mods/EPs.

How to install

It is necessary to already have a save file with all the Sims created, the house should be built, and all the necessary items should be bought beforehand since currently only Live mode is supported, build & buy mode are in experimental phase. (features might work but there is no guarantee) It is also important to have a save with time paused.

One of the PCs will act as a server and should do the following additional steps:
1. Start the launcher
2. Host a game by selecting an already created save file
3. Start The Sims 4, load the save file and enter your household
4. You should see a notification verifying your game has successfully connected to the server.

The other PC will act as remote client and should do the following additional steps:
1. Start the launcher
2. Join a game by entering the IP address of the host player (displayed in the launcher on the host machine)
3. Start The Sims 4, load the save file and enter your household
4. You should see a notification verifying your game has successfully connected to the server.

At this point you are all set up, feel free to start the time and enjoy the multiplayer The Sims 4 experience! (please note that only the server’s player can control the time)

Is this mod based on other mods? Is it safe to play with the mod?
  • While there are broken multiplayer mods out there, this one is written from scratch and it yields no security vulnerabilities. (If you don't trust it, you can still disconnect your PCs from the internet while you play on LAN.) There are some people out there who claim this mod is based on existing code or has security issues, we've asked them many times to do a developer talk about it, never received any real arguments.

Im on 1.68 still I refuse to update already got all my mods and stuff working well enough, I dont feel like redoing all of it.
I play offline on origin so it never updates, so my question is which mod are you talking about and which one would be better for me to use for my version or would I absolutely have to update to use the other mod you spoke of.
(Im downloading this one now to test it out for us, so if it doesnt work for some reason I'd appreciate it if you could link me with the other one you know of if it works)

Hi! My S/O and I would love to download this so we can play together, but I can't seem to get it to work. I believe I have done everything correctly, but when I press the "Host" button and load my game, it doesn't work. Anything I should do or check is done correctly prior to removal? Thank you in advance!
*Edit* I feel I should add I am on a laptop and he is on desktop
Me? Sarcastic? Never.

Then why does Windows 10 say that it can cause problems?

This is what I got when I clicked on the S4MP mod file

The launcher refuses to open, i had it open at one point and it ends up crashing and says that there is no path to the file and that it does not have permission or something like that. I've tried re-downloading the launcher but it just doesn't open. Sims 4 did just update, and after it did that it went through to verify the files, waited and tried to start again but it messed up my files and made the launcher crash. It crashes and uninstalls itself from my computer. feels like im getting fucking d-dossed. cause im on discord too, and I just disconnected and then reconnected immediately, I try to run the launcher, it crashes. this didn't start happening until today.

You can click on More Info then a Run Anyway button will appear. S4MP is trusted by hundreds of thousands of people, supported by some huge Sims influencers, feel free to join our Discord community if in doubt. Also, you can run a VirusTotal scan with the exe file if still in doubt.

One thing to keep in mind: always download the mod from a trusted source! (ModTheSims is a trusted source)

It seems to me that what's going on with your computer is not related to the S4MP Launcher. You can try deleting the s4mp-launcher folder from C:\Users\* your username *\AppData\Roaming and see if that helps.

This is an awesome mod, thank you
I do have a question, does it require the sims to be in a specific order, with the host being the first sim made? Asking because I made a household but I'm worried that it may set me as the sim that I made for my friend, because I made his sim first.
Also, does it work with the holiday pack? Wondering because I don't know where to click for holiday (it's the only pack that we both have, and I'm hoping to use it with this mod).
