(2024 ACTUAL) SC:C - How to ACTUALLY: Join a Co-Op session

Oh, you wanna play with your bud? Okay then, get here and read DIS!

BASIC RULES of JOINING A LOBBY

Do you really wanna play CO-OP?

Okay then, here are some basic rules you need to know:

• Ubisoft is not totally supporting SC Conviction, since it's hosting other fab-fa* games like Division, so making Private Lobby to work will be a pain in.. you know where.
  
• (Optional - hardcore difficulty) You or your friend will have to host VPN session and an in-game session - preferably the one with the better PC / better bandwidth / better network configuration.
  Be sure the network is stable and that the real Geo-location distance is not too far, or you will start to experience de-synchronicity issues and in the end you will disconnect from the live session.
  The distance between you and your team partner (real Geo-location distance) will make a big difference in quality of your further team-playing. That means if a guy lives in Australia and wants to play with a guy from Japan, then he is in trouble. Also include the distance from you and Ubisoft servers (the on which is located in your area) and the distance of it and your friend and make the presuming. (Old - actual prior 2024 update)
  
• Use Hamachi in order to host a private room for SC:Conviction and invite your friends in the group. (The group is limited up to 5 people). When they are all set within the same group, you can start the VPN and host a local area network in-game session (LAN) - for this to work, check the next section of the guide. Tested and approved.
  
• Host should possess a good game running machine, otherwise your game will run slow like his, and like a turtle.
  
• Please, disable your download clients, check if someone else is not overloading the network traffic, or if a master hacker didn't hacked your Wi-Fi security protocols (if you have one). That will reduce the amount of nervosity from both parties.
  
• Never trust other guides. Trust this, this is the real S Hit.
  
• In order to know if you really connected in lobby with your friend, ask him before this his native, legacy UPlay username, and add him in-game, maybe it will prioritize the system to connect you each other. (Old - actual prior 2024 update)

P.S. Hamachi and Tunngle is used for pirated games, if you really like the game, then support the modern devs with a lack of old-school taste in developing of games. Looks like we will need a VPN for a licensed game, amaright? :)
P.P.S. For newbies in this community, this guide may not work for PS3, or XBOX360, because I don' t own one. Get a PC instead, alright?

You, 2024 & Splinter Cell Conviction Co-Op Session Hosting

Today as the servers are completely shut by Ubisoft - including cutting of access the licensing server with all the purchased DLCs and ability to host a session via LAN - the only way to host it is to redirect all the network traffic to the local host address and then from there via the use of VPN - to invite the ones you wish to play with.

Latest fix developed by Ododo hooks into the game process and helps redirect the packets the game is sending and receiving in order to make it work via the VPN.

Ododo/scc-lan-restore
https://github.com/Ododo/scc-lan-restore

Inserting and Quoting the instructions down below to follow:

• "In order to prevent some issue like you don't see other sessions when searching for games, You will probably need to deactivate all virtual internet interfaces like the one from VirtualBox or Hyper-v.
  
• The problem is that the outgoing multicast packets to search for LAN sessions might be routed to the wrong interfaces, messing up with the session discovery. Of course if you are using a "VPN" system like Hamachi* (updated as per security reasons)* to play with remote players, you should keep active the virtual interface it creates in windows, as the packets are intended to go through this interface.
  
  
• You will need to edit C:\Windows\System32\drivers\etc\hosts and add 127.0.0.1 gconnect.ubi.com at the bottom. Then open powershell and type ipconfig /flushdns
  What it does is that it will tell the game to look for 127.0.0.1 when it is trying to connect to gconnect.ubi.com. We will handle instead the request from the game as 127.0.0.1 is our local machine. The game used to request some configuration from gconnect.ubi.com on port 3074, but this service is no longer active (altough it is still active but now on port 80 :D... But serving from localhost is more futureproof as we don't rely on external services.). This is what actually blocked the LAN menu.
  
  
• The workaround currently relies on a Python script. You can either run it from Python following theses steps below, or run directly as administator the executable created with pyinstaller.
  
  
• Install Python3 preferably from https://www.python.org/, check "Add Python to PATH", select "Customize installation" and check "pip".
  Install pip package pydivert pip install pydivert or python -m pip install pydivert
  
• Download scc_lan_helper.py from this repository.
  
• Then open Windows terminal or Powershell as administrator, and run the service with python scc_lan_helper.py and that's it.
  
• You will need to keep the program window open while playing the game.

• What does the Python script do and why do i need to run as administrator
  
  The administrator priviliedges are required because the script relies on hooking some inbound UDP packets used by the game and modifying them before they are handled by the game. There are 2 parts: a socket server listening on port 3074 and answering the game HTTP requests. The hook part which aims to fix the UDP discovery reply sent by the game host telling "i'm currently hosting a game, and those are the infos to connect". It will edit the packets so that your game client will be able to join."

Hope this helps.

The core and essence of this guide (Actual prior to 2018):

SO HERE WE ARE!

Now let's begin how to ACTUALLY make the Co-Op work for you guys.

Here are the steps:

• #1

  Both of you should launch the game.

  
  
  
  
• #2.

  Get in COOP/Multiplayer game section.

  
  
  
  
• #3.

  Press "Find a Match".

  
  
  
  
• #4.

  Get in and switch the options from Co-Op to other gamemode, then map and difficulty.

  
  
  
  
• #5.

  Now inform your COOP-friend with the new set of options you have modified.

  
  
  
  
• #6.

  Both parties should have the match settings equivalent.

  
  
  
  
• #7.

  In the same time press "CLICK HERE TO START MATCHMAKING".

  
  
  
  
• #8.

  WAIT...

  
  
  
  
• #9.

  PROFIT!

  
  
  
  
• #10.

  Now change the game-mode to your desire *only the host can do that*.
  In this case we changed to Co-Op mode.

  
  
  
  
• #11.

  Just waiting for countdown..

  
  
  
  
• #12.

  And here we are.

  
  
  
  
  
  
  
  
  
  Just lol
  
  
  I have tested everything with different friends all around the world, and this only and only the best option to do it, so I requested my friend to get in for a demonstration.

Ubisoft 2017 Server Incident Fixed

This is what happened with Conviction servers from the start of Easter Holiday.


____________
Was fixed prior in 2017.

THAT'S ALL FOLKS

THANK ME LATER OR HE WILL COME AFTER YOU

DO IT NAW!




Have fun playing.

P.S.

Whoever linked my guide on PC Gaming Wiki - Thank you, and well done. Appreciate that.

"Find a match" option won't work. The Online servers provided and hosted by Ubisoft are no longer available. The only option is to isolate the online connection check with Ubisoft and rely on VPN / Local Hosting services only.

[Nerevar]

Clicking 'Find a match' just brings me to a 'Login..." screen before saying the servers are not available.

Going into LAN and making a match seems to work though. But only sometimes.

[Freak]

can somone make a video tutorial on the updated method it makes no sense to me i cant figure out how to launch the python script through the directory

[T.TV/Undastelar]

Check if you don't have any other adapters connected and use only one connection, plus try disabling IPv6 and you should both run a good rig with not such a big distance in between you and your friend. It's all in details and this needs to be separately checked.

[DL0CK]

Hey guys, I managed to connect with my friend using the scc-lan-restore, but we get the "out of sync" error. Anyone knows if there's a workaround for that?

[T.TV/Undastelar]

Hello there, Chappler,

You can download the scc_lan_helper.py script from Ododo/scc-lan-restore Github:
https://github.com/Ododo/scc-lan-restore

Actually - this has been updated on 5th of January 2024 - https://github.com/Ododo/scc-lan-restore/releases/tag/v2

I may advise to copy the archive contents into the game directory in scc and afterwards to run an elevated PowerShell with admin rights and run scc_lan_helper.exe from the directory where you copied them.

You will have to keep the script / program window running in the background while playing the game in order for this to work.

Hope this helps

[Chappler]

I don't understand the step "Download scc_lan_helper.py from this repository." I installed pydivert and am not sure how to get the lan helper installed and running with Python. The exe does not work for me.

[I'm Panda-Man]

Go with he's the man he helped me and many others play some conviction

[T.TV/Undastelar]

That's been updated and tested. Up and running in 2024, guys. Enjoy :)

[syavikua]

probably this method from guide also doesn't work anymore, because since august 2023 Ubisoft was shut down the servers, responces for local coop with Radmin VPN on licence and pirate version. You CANNOT even join to LAN lobby because it will end up with error and crash
