The Steam version of Arknights: Endfield launches on October 15, 2026. Account data is shared across every platform, so wherever you start, your progress comes with you. Arriving the same day: the new core version Tanseiwatari and new 6-star operator Su.
The official GRYPHLINE special broadcast that aired on October 6, 2026 was, frankly, an absurd amount of information for one show. The Steam date, two new characters, 6-star weapons in the Armory Exchange, new Crisis Contract certification parameters, a ZONe ENERGY collab, a Round One collab, and even the venue and window for the first anniversary fest all landed in one sitting.
Su in particular occupies an unusual slot as a Cryo-attribute support, which means she is not just another damage pick. She buffs Cryo and Pyro allies at the same time, and that is the kind of kit that rewrites the ground rules of party building.
Here is everything from the broadcast, narrowed down to the dates and numbers that can actually be confirmed.
When does the Steam version of Arknights: Endfield launch?
The official Steam launch is October 15, 2026. Account data is shared with the existing platforms, so the base you have been building on your phone moves straight onto a full-size PC display.
| Item | Details |
|---|---|
| Steam version official launch | October 15, 2026 |
| Accounts | Data shared across all platforms |
| New core version | Tanseiwatari (new map “Su’s Painting” / guide event “Color in the Ink”) |
| Special scout “All Things Renewed” | Until November 5, 2026, 11:59 (server time) |
Calling the Steam version a “port” is not quite right. Shared data is baked into the design, so really all that has happened is that the same game gained one more front door. As someone who keeps a Steam Deck in her bag at all times, this is exactly the approach I want to see.
What gets added in the new core version Tanseiwatari?
Tanseiwatari adds the new map “Su’s Painting” and the guide event “Color in the Ink,” and it brings new 6-star operator Su into the game. The hook this time is that the map itself is built around the motif of a painting.
What makes new 6-star Su strong?
Su is a Cryo-attribute support who packs heavy damage and buffs into the same kit. She boosts the damage of Cryo and Pyro allies, and her combat skill briefly seals an enemy while applying “Brush Intent.” Enemies marked with Brush Intent take additional recorded damage, and they can also be tapped to extract “Ink Soul.” Her ultimate shortens the synergy skill cooldown of the ally in position 01.
The key detail is that her attribute buff covers both Cryo and Pyro, which lets you field combinations that normally would not mesh in the same lineup. Factor in the synergy skill cooldown reduction on her ultimate and Su reads less like a character who exists to hit things and more like one who exists to speed up the whole party’s rotation.
What kind of character is new 6-star Minho, arriving November 5?
From 12:00 on November 5, 2026, new 6-star Minho appears in the special scout “Heavenly River Drawn by Hearth Smoke.” He is an Electromagnetic-attribute vanguard who applies a special shock status and hits an area with “Thunder Momentum.”
| Character | Attribute / role | Availability |
|---|---|---|
| Su | Cryo / support (boosts Cryo and Pyro damage) | At Tanseiwatari launch / All Things Renewed runs until November 5, 11:59 |
| Minho | Electromagnetic / vanguard (special shock status, area damage via Thunder Momentum) | November 5, 2026, 12:00 |
The Armory Exchange gains the 6-star greatsword “Jade Core” and the 6-star one-handed sword “Moon Inquiry,” alongside weapon requisitions “Jade Script Requisition” and “Moon Reflection Requisition.” Crisis Contract and the Azure Trial Operation pick up two new certification parameters, “Environment: Sealed” and “Environment: Silence.” Grabbing gear or shaving down parameters, your Sanity budget is about to get very busy.
What do you get from the 300,000 wishlist milestone?
To mark 300,000 wishlists on Steam, a special frame and the rewards from every previous milestone are being handed out via serial codes. You redeem the codes to claim everything in-game.
Being able to sweep up the older milestone rewards in one go is quietly a big deal for anyone starting fresh. If you are jumping in alongside the October 15 Steam launch, this is the first thing you should avoid leaving on the table.
What is the schedule for the collabs and real-world events?
The broadcast announced a two-day pop-up at Tokyu Plaza Omotesando “Omokado,” a ZONe ENERGY collab, a Round One collab, and the first anniversary fest.
| Project | Timing / details |
|---|---|
| Pop-up (Tokyu Plaza Omotesando “Omokado”) | Two days only |
| ZONe ENERGY collab | From October 27, 2026 at AEON stores nationwide. Operator-themed packaging and a special box with a towel |
| Round One collab | Three months from November 10, 2026. Bowling, a collab karaoke room, an AR stamp rally, and limited merchandise |
| First anniversary fest | January 2027, Makuhari Messe |
Three months is a long run for a Round One tie-in. With a karaoke room and an AR stamp rally in the mix, this is less a chore you clear for in-game rewards and more somewhere you would genuinely go to hang out. A concert is said to be in preparation as an online event, and the official short manga “Voice of the Beginning: Origin” was announced as coming soon.
On the story side, future content will explore the world of Kay-chan and the mushrooms, with a teased arc in which Rhodes Island pushes across the Chalk Plains aboard a colossal mobile battleship.
What is being improved in the controls and systems?
The broadcast also detailed several quality-of-life changes. The “Loadout” feature and the mouse control tweaks in particular look like adjustments made with the Steam launch in mind.
- New “Loadout” feature
- “Awaiting Production” added to Precision Processing
- Hold the middle mouse button to aim
- Synergy skill priority can now be configured
- Automatic use of limited-time Sanity restoratives
Being able to set synergy skill priority matters a lot given that Su’s ultimate is a cooldown reduction. Whether you can reliably land the synergy you are aiming for will change how much damage the exact same lineup puts out. If there is a knock, it is that there is simply too much new material at once, and chasing all of it across the three weeks between October 15 and November 5 is going to be a grind. Setting your own priorities is the only way through.

Arknights: Endfield news roundup
The Steam version launches officially on October 15, 2026, with account data shared across all platforms. New core version Tanseiwatari adds the new map “Su’s Painting” and the guide event “Color in the Ink,” and brings in new 6-star Su as a Cryo-attribute support. The special scout “All Things Renewed” runs until November 5, 2026, 11:59 (server time).
After that, new 6-star Minho arrives in the special scout “Heavenly River Drawn by Hearth Smoke” from 12:00 on November 5, 2026. The ZONe ENERGY collab starts October 27 at AEON stores nationwide, the Round One collab runs three months from November 10, and the first anniversary fest takes place at Makuhari Messe in January 2027.
The heaviest thing in this announcement is not the Steam date, it is Su’s design, the fact that she buffs Cryo and Pyro at once. In a game where attributes dictate your lineup, a character who removes that restriction arriving in the support slot has big consequences. On the flip side, a schedule that drops two new 6-stars, two 6-star weapons, and two new certification parameters between October 15 and November 5 is honestly packed solid. Plan to chase all of it and you will run out of Sanity.
Take Su for lineup flexibility, or take Minho to refresh your vanguard. The right move is to decide now, with that November 5, 11:59 deadline in view.
