Works on all platforms.
To get on PC/ PS, you need an xbox account
1. Follow the link and create an account
https://www.xbox.com/ru-RU/live
2. Follow the link from point 1 and click log in, then finish creating a profile (specify age 18+)
3. Follow the link to your main Ubisoft account and link the xbox
https://account.ubisoft.com/en-GB/account-information
As a result, you should have an xbox + account linked to your main platform account (PC or PS)
