Might need to install Ubisoft Connect from Proton Tricks. Once the game is installed find the installation folder using the command "sudo find / -name "Odyssey". Once in the installation folder go to videos folder. Create a new direcctory called "test" and move all bk2 files into that folder using the commond "mv *.bk2 test". One last thing remains, let's say your language is english, go to the "en" dorectory; create test directory and run the command again "mv *.bk2 test". We are running these commands because the game crashes if the intro video plays, this skips them.

The game will either fail to install Ubisoft connect without tinkering or get stuck at opening videos
