There was a message at first start about no/corrupted save file, but i had no problem saving progress, so believe it can be ignored.
No problems using the latest proton and default settings. Uploaded a community layout for Steam Deck controller with renamed buttons and backgrip buttons.

Didn't need to change or do anything other than just installing and clicking play. Old issue of the launcher not updating or what have you is fixed now, and honestly should be moved from unsupported to either playable or verified.
The game is not running directly from Steam. I was able to install Ubisoft Connect and then install the game from that launcher.
issue with cloud save
The game is not running directly from Steam. I was able to install Ubisoft Connect and then install the game from that launcher. Guide:
- On Steam Deck, go to Desktop mode and in your browser navigate to Ubisoft Connect Download page
- Download Ubisoft Connect, add the exe as a non steam game. Change compatibility to Proton latest version
- Launch the Ubisoft Connect exe. Install Ubisoft connect, log in.
- Install the game/this works for other Ubisoft games in your library**Except for EasyAntiCheatgames/
- While still in Desktop mode, navigate to the Ubisoft Connect exe in Steam and in properties change the launching path to the now installed Ubisoft Connect Launcher/You can find the location in a newly created :C folder in /home/deck/.steam/root/steamapps/compatdata/33320/pfx/drive_c/Program Files (x86)/Ubisoft/
- After your game has finished downloading, close Ubisoft Connect.
- Launch Ubisoft Connect from your Steam Library again while in Desktop mode/If you skip this part you might have issues in gaming mode where Gamescope can't decide between showing you the game or ubisoft connect and keeps flashing/
- Navigate back to gaming mode and launch the Ubisoft Connect exe
- This will now launch Ubisoft Connect and from there you can select your downloaded game and click play.

33320 uplay
Wasn't able to launch the game by default, but got it to work on the Steam Deck following the advice here and adapting it to SteamOS.
Steps:
- Install the game through Steam and launch it. It will install a bunch of stuff, but fail to update uplay and end on a cut-off error message. Use the trackpad to click on the X to close the window.
- Boot into the desktop and install protontricks from Discover, if you don't have it yet.
- Open a terminal and type
flatpak run com.github.Matoking.protontricks 33320 uplay
- if you installed the game on an SD card, you first need to give protontricks access to your Steam Library on there either typing
flatpak override --user --filesystem=/path/to/other/Steam/Library com.github.Matoking.protontricks
(change the path accordingly) or using Flatseal
- if you installed the game on an SD card, you first need to give protontricks access to your Steam Library on there either typing
- Complete the setup, go back into the GamingUI, and launch the game again. Uplay should update now, install some more stuff, and then launch the game.
- Finally, change the Controller Layout to e.g. Gamepad with Joystick Trackpad and enjoy
I haven't played much into the game yet, but the opening cinematic and opening area played without any issues.
