Arknights: Endfield Steam Version Arrives With Save Carry-Over
The account linking and the file-copy workaround are the migration pitch: GRYPHLINE is moving existing PC players onto Steam without asking them to restart their Talos-II progress or re-download the client.
Reporting from 2 sources: Denfaminicogamer, Game Spark.
GRYPHLINE released the Steam version of Arknights: Endfield on October 15, 2026. The port adds Steam screenshot and Game Recording tools, letting players capture with F12 and keep clips together in Steam's Recordings and Screenshots. Existing players can link their GRYPHLINE account to Steam to continue with prior progress. A Steam Community guide by SanderLy describes copying already-downloaded game files to skip a fresh download.
The Steam build supports GRYPHLINE account linking, so players already on the PC launcher version can log in with their existing account and continue rather than start over. The store page states a GRYPHLINE account is required.
For players who do not want a second download, a Steam Community guide published by SanderLy, titled "Skip the Steam Redownload," walks through installing the game on Steam, cancelling the download, uninstalling it, closing Steam, then copying the contents of the EndField Game folder from the GRYPHLINK install location into the steamapps common Arknights Endfield folder.
