Arknights: Endfield: new Steam account linking guidance for existing progress (17 October 2026)

Endfield's new guidance requires a Gryphline link on the first Steam login. Players continuing from another platform should use the account holding their existing character. Choose the linking route that matches the way you already sign in before starting a separate registration.

Existing email users choose Log Into Existing Email Account & Link, enter the address belonging to that Gryphline account and request a verification code. Review both Steam and Gryphline identities on the confirmation screen before selecting Confirm so the link uses the intended account.

Third-party login users without a linked email first open Gryphline Account Center with their usual login. Link an email not already registered to Gryphline, then use it for Steam linking. Registering an unrelated Gryphline account is not the route described for continuing an existing character.

Players who have never registered a Gryphline account can choose Register & Link on Steam's linking page and follow the registration process. This is a separate route from linking an existing account. First check whether previous play used a third-party login that already holds your character.

The notice also describes unlinking Steam. In the game, open Settings, then Platform & Account, and use Go beside Account Center. Alternatively, sign into Gryphline Account Center with the linked account and follow its unlinking instructions. Check the signed-in account before making that change.
