Arknights: Endfield version 1.1 update ‘Old Deep Water Dies, by Rising Tide It is Denied’ launches March 12

On March 12th, GRYPHLINE and Mountain Contour will release a free update for their 3D RPG, Arknights: Endfield. The update, titled “Old Deep Water Dies, by Rising Tide It is Denied,” will be available to all players.

Our first big update is here, bringing significant improvements and new features to the core game. This update follows a successful launch that exceeded our expectations.

According to producer Light Zhong, Arknights: Endfield has attracted far more players and activity than anticipated, and the recent Version 1.1 update is a direct result of the community’s enthusiastic response.

Here are the patch notes:

New Content

We’re adding more staff and growing our artificial intelligence system with a new approach focused on water and industry.

New Operators
- Tangtang (6-star Caster) – Described as a “one-girl team,” Tangtang is specialized in AOE Cryo damage and support. Her Ultimate, DA CHIEF SEES YOU!, introduces a powerful new tactical layer by immobilizing all enemies within its range – including bosses – allowing her squads to create decisive damage windows.
- Rossi (6-star Guard) – The only operator currently capable of converting Arts Infliction on enemies into Vulnerability (defense break). This specialized mechanic positions her as a vital force multiplier for Physical-focused squads, as she shreds enemy defenses to facilitate massive damage output from the team’s primary carries.
Hydro-Industrialization
- New Tech – The Hydro Mining Rig allows players to mine Cuprium, a new industrial resource that uses water flow instead of electricity. Unlike existing facilities, Hydro Mining Rigs harness water flow to automate mineral collection, requiring no connection to the power grid.
- New Logistics – New Conduits for long-distance liquid transport and Water Treatment Units for processing sewage.
  Forges of the Sky Expansion: Placement limit for Forges of the Sky increased to four units, significantly raising the production ceiling for endgame resources.
World and Story Expansions
- New Wuling Area – Qingbo Stockade
- Story – The Endministrator can investigate the Qingbo Stockade, where tensions with Wuling City are boiling over due to the arrival of Nefarith and Ardashir.

Player Rewards and Progression

Besides the initial offer of 135 free tries, players will now receive even more rewards!

New Beginner Support – After reaching specific milestones in Chapter 1, players will receive a new beginner mission reward totalling 10 Chartered Headhunting Permits. Endministrators who have already completed these requirements can claim their rewards directly from the event page upon the update.
Sign-In Events – “Gently Flows Qingbo” and “Pearl of the Pack” (7-day logins) for limited-time permits.
Battle Pass Update: The Protocol Pass now allows for periodic acquisition of Basic Headhunting Permits.
Limited-time Activities
- Exploration Day – Farming at Originium Science Park.
- Survival Training – Try a different take on combat using only Industrial Explosives!
Systemic Rewards – AIC Quota acquisition has been expanded, with players now receiving Quotas for obtaining 4, 5, and 6-star operators for the first time. For operators acquired prior to the update, the corresponding Quotas will be distributed via in-game mail.
Advanced Gear Optimization – The introduction of the Valley Multi-Line Engraving Kit – available through the Stock Redistribution system—allows players to create Essences with three customized stats. This provides a high-level path for Endministrators to optimize endgame weapon builds and reduce RNG friction.

Community-Driven Optimizations

Based on what people told us after the initial release, Version 1.1 includes major updates to make the game easier and more enjoyable to use, especially for those playing with a controller.

Construction Precision – The buffer range for power lines has been extended to 20m (100m total), and connection will no longer snap during dialogue or combat triggers. Controller users can also now move facilities by long-pressing a dedicated button.
Exploration HUD – A new feature allows the minimap and game map to be accessed while using ziplines, improving navigation across the vertical terrain of Qingbo Stockade.
Combat Ready – Operators now enter Protocol Spaces with maximum HP and Ultimate Energy. Additionally, the Red Flash enemy attack telegraphs have been re-tuned for better visibility during chaotic encounters.

In Version 1.2, we’re significantly expanding Talos-II. The next story chapter will focus on the Endministrator and Tianshi Zhuang working together to protect the Xiranite Dam from an unexpected attack by Ardashir. This update will also add two new maps, a new outpost, and a completely new way to produce resources at the AIC Factory using a fluid-based system.

You can now play Arknights: Endfield on PlayStation 5, PC (through the official launcher and Epic Games Store), and mobile devices (iOS via the App Store and Android via Google Play).
