Gryphline's 3D real-time strategy RPG just took its biggest platform step yet, and cross-platform progression is why it matters — existing players can continue the same account on PC. Sanctuary of Ink adds two playable operators, Si and Argent Flow, plus a countryside inn to farm and cook in. As of midday October 15, Steam's official review API showed 290 reviews with 272 positive, about 93.8%.
一、The Steam version arrives October 15: official announcement and store page differ by a day
Publisher GRYPHLINE and developer Mountain Contour state plainly that the Steam version supports cross-platform progression: players who already put time in on mobile or console can carry the same save onto PC. The studio previously announced more than 35 million pre-registrations ahead of the game's January 2026 launch.
The Steam store page lists October 14 as the release date
Steam's official store page for the game (App ID 4732690) carries a release date of October 14, 2026, one day earlier than the press release. That gap is routine for cross-platform launches and usually comes down to time zones and store review timing, not a delay. The same page confirms free-to-play, developer Hypergryph, publisher GRYPHLINE, and Windows as the only supported platform so far.
Minimum PC specs: Windows 10 64-bit, i5-9400F, 16GB RAM
The store page's minimum requirements are 64-bit Windows 10, an Intel Core i5-9400F and 16GB of RAM. That memory floor sits above most gacha clients, which suggests the PC build is not simply a phone interface on a bigger screen.
二、First-day reception: 272 of 290 Steam reviews are positive
As of midday on October 15, Steam's official review endpoint returned 290 reviews with 272 positive, about 93.8%, for a "Very Positive" rating. The store page showed a smaller review count at the same moment because the endpoint counts every language and purchase type while the page defaults to one filter. On mobile, the US App Store listing shows version 1.6.3, updated October 14, with 6,916 ratings averaging 4.48 out of 5.
三、New operators: Si's Inksoul transfers damage, Argent Flow charges on horseback
Si is a Feranmut Proxy who lives inside a landscape painting of her own making, and the new chapter puts the Endministrator in her inn. In combat she draws an Inksoul out of an enemy and routes the damage and effects dealt to it back to the original target; even when an enemy moves out of range, players can keep hitting the Inksoul or use a skill on it to interrupt a charging attack. She also buffs Cryo and Heat teammates.
Argent Flow works differently: sword and spear techniques plus mounted charges on his warhorse, Nuli, with an ultimate that rides in before leaping for a finishing strike. Both operators become available through recruitment events rolled out across the update.
四、The real change is systems, not the gacha
The update adds a full management layer: grow crops, raise animals, turn produce into dishes for visiting guests, and spend the earnings on expanding the farm and the inn. Different operating themes unlock more recipes.
Contingency Contract adds enemy attack patterns for the first time
The high-difficulty Contingency Contract mode returns as Indigo Experimental Operation with selectable modifiers. The official example is telling: one modifier sharply boosts combo-skill damage but temporarily blocks further combo skills after every two casts. For the first time, selected modifiers also give enemies extra attack patterns rather than only limiting the player.
The soundtrack raises the bar again
The announced contributor list includes Zhai Jinyan, composer on Black Myth: Wukong; Ludvig Forssell of Death Stranding; Chinese band 8:48; and returning musician Crywolf, spanning color bass, afrobeat and UK garage.

五、Cross-platform progression matters more than the Steam listing
Historically, a gacha game arriving on PC meant starting over. This time the pitch is one account with an extra door into it. The side effects are real too: once accounts are live across several platforms, support, anti-cheat and save-conflict handling all get more expensive, which is exactly why many gacha titles delay the move for years.
六、The risk: 290 reviews means there is no rush yet
290 is not a big number. Most day-one players for a gacha game on Steam are existing users switching screens rather than new customers, so an extra platform does not automatically mean extra revenue — it means maintaining one more client. The same day, the Japanese server of Arknights published main story Chapter 17, alongside a secondary-creation contest with Naver Webtoon, so the studio is pushing story, version content and UGC in the same week. That is good news, and also a squeeze on the time budget of anyone playing just one gacha game.
七、My read: the competition is shifting from characters to systems
Gacha banners are losing marginal pull: every title is fighting over the same players and the same wallet, and one new character brings fewer returning users each quarter. Putting weight on inn management, Contingency Contract modifiers and cross-platform saves is really about giving players a reason to stay. What makes the Steam version valuable is not another store page; it is a long-term save that works across devices.
