The current Steam version of AC Brotherhood has an offline mode that allows you to play the game without requiring you to login to Ubisoft or even have an active internet connection. Normally this offline mode is removed as soon as you launch it for the first time, because the Ubisoft Game Launcher will contact Ubisoft's server and automatically update itself to Ubisoft Connect.

But if you use Windows Firewall to block the launcher from using the internet, you can stop that update from happening and play the game completely offline. This only needs to be done once.

Ubisoft Connect cannot be installed on your computer for this to work. If you play any other game[www.pcgamingwiki.com] that requires Ubisoft Connect after applying this fix, you will need to repeat steps 1 and 2 below before you can go back to playing AC Brotherhood in offline mode. It only takes a minute to do that, but just keep it in mind.

In other words: This guide probably won't be useful to you if you're going to be playing AC Brotherhood and other Ubisoft games simultaneously, like Rainbow Six Siege for example.

Also, for obvious reasons, you shouldn't bother with this guide if you intend to play the multiplayer portion of AC Brotherhood. Ubisoft Connect is required for multiplayer.

As of December 2021, I've verified that this works in both Windows 7 and Windows 10, although the pictures and descriptions may be slightly off for a couple of steps depending on which OS you are using. If you're having difficulty following the guide, please leave a comment and I will try to help you out.



1) - Windows 7: Open the Windows Control Panel and select Uninstall a program.
- Windows 10: Open the Start Menu, click Settings, then click Apps in the new window.

2) Uninstall Ubisoft Connect, Uplay, and Ubisoft Game Launcher.

(You will probably only have one of these installed. If you have more than one, uninstall Ubisoft Connect first, then Uplay, and finally Ubisoft Game Launcher.)



1) Download AC Brotherhood on Steam, but do not launch it yet.

(If you launched it already and installed Ubisoft Connect, repeat Step 1 then continue from here.)

2) Download UbisoftConnectInstaller.zip from here:

3) Open the .zip file and extract UbisoftConnectInstaller.exe to the folder where AC Brotherhood is installed on your computer. The correct folder should already have a different UbisoftConnectInstaller.exe file inside of it. Confirm overwrite when asked.

(The default location is C:\Program Files (x86)\Steam\steamapps\common\Assassins Creed Brotherhood\)

If you've completed this guide previously and Ubisoft Game Launcher is still blocked by Windows Firewall, you can stop here and play the game. If you're not sure, repeating the process won't hurt anything.

1) From the location where your Steam games are installed, go to the following folder:

Assassins Creed Brotherhood\Support\GameLauncher\

Then run UbisoftGameLauncherInstaller.exe to install the Ubisoft Game Launcher. Once it's finished installing, move on to the next step.



1) From the Windows desktop, type firewall in the Start Menu's search box. One of the results should be Windows Defender Firewall with Advanced Security - select that to open it.






2) In the Firewall window, look in the far-left panel and click Outbound Rules so that it is highlighted.








3) Now in the far-right panel under the Actions header, click New Rule... to open the New Outbound Rule Wizard, and use the following options for each step:






- For Rule Type select Program and click Next.









- For Program select Browse... then navigate to the location where you installed the Ubisoft Game Launcher and double-click UbisoftGameLauncher.exe to select it for your new firewall rule. Then click Next.

(The default location is C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\)


- For Action select Block the connection and click Next.








- For Profile make sure Domain, Private, and Public are all checked, then click Next.








- Type "Ubisoft Game Launcher" in the Name field and click Finish. The new outbound rule will appear at the top of the list.







4) Close the Firewall program.



That's all. Now you can play AC Brotherhood without having to bother with Ubisoft or Ubisoft Connect.

When you launch it from Steam, a window that says "Checking for updates" will appear for a moment, followed by a login window. In the bottom-right corner of the window is a button that says OFFLINE MODE - click that and the game will start.

The firewall block is permanent, so you don't need to repeat this process if you uninstall AC Brotherhood and then re-install it at a later time. Just download the game on Steam and play.

However, if you need to disable the block, here is how you do that:

1) Open the Windows Firewall program again (search for "firewall" and click Windows Defender with Advanced Security)

2) In the far left panel of the Firewall window, click on Outbound Rules, then scroll down until you find the entry for Ubisoft Game Launcher (the list is sorted alphabetically, so it should be near the bottom).

3) Right-click that entry, and then select Disable Rule. To re-enable it, right-click and select Enable Rule.

This is important to remember, because most other Ubisoft games that were released post-2009 require a Ubisoft account and an internet connection to play (no offline mode possible).

For that reason, I recommend disabling the firewall block once you are finished playing AC Brotherhood, to avoid problems when trying to play other Ubisoft games.

I hope this guide is useful to you and allows you to enjoy AC Brotherhood without the usual Ubisoft headaches. If you have any questions, post a comment and I will try to help.
