How to connect my account to Steam?

You can link your main RAID account to Steam
Official guide

You can link your account to Steam:

1. Install the Plarium Play app from the official website plarium.com on your PC
2. Log into your current Plarium ID (a detailed guide on how to do that is here here)
3. Tap on Settings in Plarium Play
4. In the opened window, tap on Steam in the Linked Accounts tab and specify your login credentials for Steam
5. Log into Steam using the linked account
Afterward, download RAID: Shadow Legends from Steam.

Please note if you have already downloaded RAID from Steam before linking the existing account to it, you will start a new account.

If, by accident, you launched the steam version without linking your main Raid account you can add your newly created steam account in your Plarium Play launcher and add an email address to this account. Verify the email address, after that you can unlink your steam account from the accidental Raid account then link your steam account to your desired Raid account. Hope this helps
