Why Updating the Seamless Co-op Mod is Essential

Why Updating the Seamless Co-op Mod is Essential

Before diving into the steps, it's crucial to understand why this update is necessary. With the release of the new DLC, Shadow of the Erdtree, more maps and content have been added, making the previous version of the Seamless Co-op Mod obsolete. An updated version of the mod not only ensures compatibility with the new content but also irons out potential bugs and enhances your multiplayer experience.

Step 1: Download the Latest Mod Version

First things first, you need to visit NexusMods and download the latest version of the Seamless Co-op Mod. Ensure you have an account, if not already, as downloads require user registration.

Step 2: Extract the Mod Files

Once the download is complete, you’ll need a file extraction tool like WinRar or 7Zip. Right-click on the downloaded file and select "Extract Here" to unpack the contents. A new folder containing all the mod files should now be present.

Step 3: Locate the Elden Ring Installation Directory

Navigate to the Elden Ring installation directory on your computer. For most users, the typical path will be:

C:\Program Files (x86)\Steam\steamapps\common\Elden Ring\Game

Locate the Elden Ring Installation Directory

If you've installed the game in a different directory, make sure to find that specific path.

Step 4: Move the Mod Files

Drag all the extracted files from the mod folder into the Elden Ring "Game" directory. When prompted, select "Replace all files." This step ensures that the new mod files overwrite the old ones, activating the updated mod.

Step 5: Handle the ersc_settings.ini File

Within the SeamlessCoop folder, look for a file named ersc_settings.ini. Drag this file into the main SeamlessCoop folder if it isn't already present. This file is critical for setting up your co-op environment correctly.

Step 6: Set Up a Secure Password

Open the ersc_settings.ini file using any text editor like Notepad or Notepad++. Scroll to the bottom until you find the [Password] section. Here, you’ll need to create a co-op password. Enter your desired password in this format:

Set Up a Secure Password

cooppassword = YourSecurePassword

Make the password something easy for you and your friends to remember but hard for others to guess. Save the file once done.

Step 7: Create a Desktop Shortcut for Easy Access

Locate the ersc_launcher.exe file within the SeamlessCoop folder. Right-click on it and select "Create a shortcut". Move this shortcut to your desktop for convenience. This will be your go-to launcher for playing Elden Ring with the Seamless Co-op Mod active.

Step 8: Launch Elden Ring Through the New Launcher

Now that everything is set up double-click the ersc_launcher.exe shortcut on your desktop to launch Elden Ring. Your modded game should now be up-to-date, and you can enjoy a seamless co-op experience.
