Accessing Desmond's Journey and The Lost Archive Post Update
By Vitharr
The update that removed multiplayer from the game also gutted the files required for accessing both Desmond's Journey and The Lost Archive DLC, resulting in users being stuck in an infinite loading screen when attempting to access this content. This guide will be step-by-step instructions on how to regain access to these parts of the game, by down-patching to an older version of the game. All steps were done on Windows, so you may need to follow different files paths if you are running Mac or Linux.

Getting Started
The first thing you will need to do is enable Steam Console. Make sure Steam is open, and then press the Win Key + R Key. A search bar should appear, and you will want to enter the command:
steam://nav/console
Accessing Desmond's Journey
With Steam Console now open, enter the following command:
download_depot 201870 201871 3788743185036498953

You should get confirmation that the files are downloading. Once you get confirmation that the download is complete, which may take a while, you are going to want to navigate to where they were downloaded.

You will find the files in your Steam library, under:
SteamLibrary\steamapps\content\app_201870\depot_201871
Now you are going to copy all of the files in this folder, and paste them into your game's library, under: SteamLibrary\steamapps\common\Assassin's Creed Revelations Overwrite any files, if prompted.
Now you are going to copy all of the files in this folder, and paste them into your game's library, under:
SteamLibrary\steamapps\common\Assassin's Creed Revelations

Overwrite any files, if prompted.
Accessing The Lost Archive DLC
This section is only relevant if you own The Lost Archive DLC. You can skip this, if you do not.
First, you must complete the previous section for down-patching the main game. Once you have done that, go back to the Steam Console and enter:
download_depot 201870 201882 6947412385247558407

Wait for the confirmation that the download is complete, and then navigate to the download location:
SteamLibrary\steamapps\content\app_201870\depot_201882

Once again, you are going to want to copy all of the files in this folder, and place them into your game's library. Overwrite any files, if prompted.
Final Steps
The last thing we must now do is delete systemdetection.dll, which is located in your game's library. This file is known to cause many issues on modern systems, and, for me, caused textures to constantly flicker. There are no down-sides to deleting it, as far as I'm aware.
Now you should be able to boot up your game, no problem. It is perfectly safe to launch this game through Steam, whilst on-line, as well as logging into Ubisoftconnect. You will even be able to unlock achievements, still. The only thing to be aware of, is if Ubisoft does update the game, you will likely have to go through this entire process, again. Hopefully, though, that update will fix the issue this guide was made to address.

Thank you so much! This worked fine for me, accessing Desmons Journey. However, to access The Lost Archives, you also have to copy a savegame file into your game, see comment here in this comment section from April 19th 2024.

When deleting systemdetection.dll make sure to delete it permanently, even if it is in the bin, you have to erase it from your computer

After doing this, I'm not able to run the game as it fails to connect to ubisoft connect.

broo muchas gracias, haciendo los pasos de la guía me funcionaron los recuerdos de desmont (en la isla) para habilitar el dlc tuve que ir a nexusmods para reemplazar el 1.save en la carpeta de ubisoft y eso ya habilito el dlc en mi juego de steam.

Manually downloading Desmond's Journey files from the steam depot and manually patching it as described here works on Linux (though steam puts the files in a different directory), but annoyingly then the game fails to load with the steam overlay enabled and the steam overlay had to be disabled. Which sucks because a couple years ago when I played through this game on Linux both Desmond's Journey and the steam overlay had worked at the same time.

Downpatching the dlc is not needed at all, and downpatching the base games is also not needed except for the ACRPR.exe file. That's the only thing that's missing.
