Hey there guys!
Sorry for the delayed response. I've taken a look at our supported controllers, and the PS5 Dualsense controller is listed as a supported controller for PS5 only. We're sorry for any inconvenience caused.
In future, please ensure that you post in the correct forums for your query. You are currently in the Assassin's Creed Legacy Player Support forum. I've now moved your thread to our Assassin's Creed: Valhalla Player Support forum.
If you need further support, please feel free to open a support ticket or to reach out to us on our new dedicated forums! Thanks!
