Claudia is a mini launcher for the Assassin's Creed Brotherhood Multiplayer, made by siohaza on Discord & GitHub.

It hooks into ACBMP.exe to:

• Redirect Ubisoft multiplayer endpoints to community-maintained services without requiring hosts file modification
• Allow custom login credentials
• Improve controller compatibility on modern systems by forcing XInput over legacy DInput (DirectInput)
• Optimize/Fix CPU affinity for smoother performance

For more information, check out its repository: Claudia on GitHub

The Ubi Orbit API is part of Ubisoft's online services layer and digital rights management (DRM) for several titles. After Assassin's Creed Brotherhood's Multiplayer, it was also used to authenticate players and exchange credentials with the game servers.

Orbit, an emulator by koteykaby on GitHub, allows to launch supported multiplayers with custom login credentials. For more information, check out its repository: Orbit on GitHub

Animus Launcher is an advanced mini launcher for Assassin's Creed Multiplayer titles, made by iassassintv. It currently supports Brotherhood and Revelations.

Unlike Claudia, it does not inject into the game executables and is used to:

• Work along with Claudia for Brotherhood and uses its capabilities
• Download required manifest/multiplayer files from the Animus Network (derived from Steam and Ubisoft Connect builds, may include some changes in order to play)
• Use custom login credentials along with Claudia or the Orbit emulator
• Connect to the Animus Network VPN (SoftEther) using Windows built-in VPN: SSTP on Windows 8 and later, or L2TP on Windows 7
• Point Ubisoft services at community endpoints by updating the system hosts file
• Provides additional launcher and/or game settings

All changes made during launcher or gameplay sessions are automatically reverted once you exit the game or close the launcher, ensuring your system remains unchanged. This includes temporary VPN configuration, applying modified versions of original game files, and updating the hosts file for community service redirection.

Assassin's Creed Multiplayer titles rely on peer-to-peer connections, and the implementation of STUN, TURN, and relay servers by Ubisoft has not yet been fully understood. Additionally, peer-to-peer connectivity is heavily affected by NAT types, which can introduce further complications. Using a VPN helps bypass these limitations, providing a more stable and reliable way to play.

The Animus Launcher should automatically connect to the VPN upon launch. If it fails to connect, try the following:

1. Make sure your system is disconnected from any other VPN or proxy service
2. Check if your system can establish the connection:
   1. Open Powershell
   2. Execute the following command:
      Test-NetConnection vpn.animusnetwork.com -port 443
   3. RemoteAddress must point to 141.147.0.245, otherwise your DNS is resolving incorrectly
   4. If TcpTestSucceeded returns False, your router or ISP may be blocking outbound connections on TCP port 443
3. Check if your Windows firewall or any other is blocking the outbound connection
4. Reset your VPN & Proxy network adapters:
   1. Open Device Manager
   2. Go to View > Show hidden devices
   3. Right-click and uninstall all VPN/Proxy adapters
      (especially WAN Miniport (...) adapters)
   4. If prompted, also remove the drivers by checking the checkbox
   5. Restart your computer allowing Windows to reinstall the adapters
5. Start the Animus Launcher and retry connecting to the VPN

The ACRMP.exe may fail to start due to missing runtime components. The game requires:

• Microsoft Visual C++ Redistributables (x86 & x64):
  2005, 2008, 2010, 2012, 2013, and v14
• DirectX End-User Runtime

To resolve this issue:

1. Uninstall all installed versions of the
   Microsoft Visual C++ Redistributables by:
   1. Opening the Control Panel
   2. Navigating to Programs > Programs and Features
   3. Uninstalling all Microsoft Visual C++ Redistributables
2. Reinstall all Microsoft Visual C++ Redistributables
   (x86 & x64) from our bundle
3. (Re)install the DirectX End-User Runtime
4. Try launching ACRMP.exe again

Since Assassin's Creed Brotherhood and Assassin's Creed Revelations use the older DInput controller system, while modern controllers rely on XInput, triggers or controller detections may not function correctly. In this case, Claudia forces the game to use XInput. However, Claudia only supports Assassin's Creed Brotherhood. For Assassin's Creed Revelations, please follow the PadForge setup guide at the bottom of the Setup page.
