Liino's rate-up closes with the next maintenance in Endfield 1.4
Version 1.4 'Homecoming' split its two 6-star operators into back-to-back windows. Arcane's banner shut on August 9; Liino's opened the same hour and runs until the next maintenance. A Steam wishlist campaign has been running alongside since August 13.

Arknights: Endfield is a 3D strategy RPG from Gryphline, part of the Hypergryph family. It carries the original Arknights setting into a different genre entirely: you build a frontier base and lay out resource lines while running real-time combat on top. Version 1.4, “Homecoming”, opened with the July 16 maintenance on the Asia server.
The two 6-stars do not overlap
- Arcane: July 16 to August 9, 11:59. Already closed.
- Liino: from August 9, 12:00, until the next maintenance. This is the one still open.
So the only banner you can act on right now is Liino, and its end is pegged to “the next maintenance” rather than a printed date. Whenever the next version schedule is announced, that is your deadline. If you have been saving, settling it before the notice lands is the safer order.
A Steam wishlist campaign is running ahead of launch
Since August 13, adding Endfield to your Steam wishlist unlocks a commemorative portrait frame and other rewards. The campaign runs until the official Steam release.
The rewards are small, but the campaign running at all means the Steam release has not landed yet. If you are playing on mobile or the official launcher, it is worth checking how account linking will work before then.
