Arknights: Endfield Version 1.3 sends players to Sword Vault Dale on June 5

Arknights: Endfield is lining up its next big content push with Version 1.3, titled Sketches of Lost Heirlooms, and this looks like a proper expansion rather than a polite little patch with two buttons changed. The update arrives on June 5 and takes players into Sword Vault Dale, a ruined new region full of floating cliffs, buried secrets and Talos-II mystery fuel.

The playable roster also grows with Mi Fu and Camille, while Contingency Contract mode gives the update a stronger challenge hook for players who like their RPG strategy with a bit more pain attached. For mobile players, this matters because Endfield is still trying to prove it can be more than a beautiful cross-platform promise. A new region, new story thread, new operators and deeper modes are exactly the kind of update it needs to keep attention from drifting away.
