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
• 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.
