Steam and the 300,000-wishlist rewards
According to Famitsu and Automaton, Arknights: Endfield launches on Steam on October 15, 2026, the same day as the new update. The game’s Steam page opened in August, and its wishlist count has passed 300,000. Each milestone comes with a reward: 8,000 T-Creds at 30,000, upgrade items at 100,000 and 200,000, and a commemorative portrait frame at 300,000. According to Automaton, players claim the rewards in game with the code ENDFIELDSTEAM.
The Steam version shares data with the other platforms through a GRYPHLINE account, so players on mobile or the launcher can move to Steam without losing progress. The exact opening time on October 15 has not been officially announced.
What is in the Sanctuary of Ink update?
- Si: a 6-star Cryo support character, an inn owner who uses “living ink” to draw ink spirit power from enemies. The banner runs from the update’s launch until November 5.
- Argent Flow: a 6-star Electric character who wields a spear-sword and rides the warhorse Nuli. The banner starts on November 5.
- New content: the “Si’s Painting” area, the Contingency Contract challenge mode returning, farm and inn mini-games, and several improvements such as saving equipment sets and better mouse target selection.
What kind of game is Arknights: Endfield?
Arknights: Endfield is a free 3D real-time tactical RPG set on the planet Talos-II in the Arknights universe. You play the Endministrator, leader of Endfield Industries, fighting while building and automating factory production lines. The game is developed by Hypergryph and published by GRYPHLINE, and launched globally on January 22, 2026 on PC (its own launcher and the Epic Games Store), PS5, iOS and Android, with Vietnamese support.
In Japan, Endfield also has a collaboration with the energy drink ZONe ENERGY from October 27, with the entertainment chain Round1 from November 10, and a one-year anniversary festival at Makuhari Messe in January 2027.
OtaHub’s take
Coming to Steam is a logical step for a game whose factory building suits a mouse and keyboard. For Vietnamese players, Endfield already has Vietnamese, and shared data means you can start on Steam and keep playing on your phone. If you are looking for a gacha game different from Genshin, October 15 is a good time to jump in, with new characters and wishlist rewards both on offer.
