The world of Talos-II is about to expand once again as Arknights: Endfield prepares for its highly anticipated Version 1.3 update, “Sketches of Lost Heirlooms.” Revealed during the latest version preview livestream, the update introduces a brand-new region, fresh playable characters, major gameplay improvements, and the arrival of one of the franchise’s most iconic challenge modes. According to official announcements, the update is scheduled to launch on June 5, 2026.

The preview program showcased how the developers continue refining Endfield’s blend of action RPG combat, industrial automation systems, and deep worldbuilding. Fans were given a closer look at the mysterious Sword Vault Dale region, alongside new operators Mi Fu and Camille, both of whom are expected to significantly impact team-building strategies.

One of the biggest highlights of the update is the introduction of Sword Vault Dale, a forgotten frontier hidden within Talos-II. The region features ancient ruins, broken fortresses, floating cliffs, and remnants of lost civilizations. Players will work alongside the Wuling Watch to uncover the secrets behind the so-called “Lost Heirlooms.”

The environment shown during the preview carries a strong atmospheric identity, blending traditional Eastern-inspired architecture with Endfield’s futuristic industrial aesthetic. Community discussions have already drawn comparisons to classic Arknights lore, especially with references tied to Chi Xiao and Wuling history.

Version 1.3 introduces two highly anticipated operators.

Mi Fu

Mi Fu arrives immediately with the update launch and appears to be deeply connected to the main storyline. As captain of the Wuling Watch, her narrative revolves around revenge against her former masters in the event “A Fistful of Reflections.”

Combat-wise, Mi Fu is described as a high-mobility Physical Guard capable of chaining attacks and skills together into devastating combos. Her aggressive playstyle emphasizes continuous offensive pressure, making her appealing for players who enjoy fast-paced melee combat.

Camille

Camille joins later during the version cycle and is already generating excitement among fans because he is reportedly the game’s first male 6-star operator.

A Keeper from Seš’qa specializing in criminal investigations, Camille’s story event “Danse Macabre” focuses on a mysterious blood-sample case that spirals into a darker conspiracy. On the battlefield, he functions as a Heat Vanguard who accelerates team skill rotations and enables combo-oriented gameplay.

The return of Contingency Contract in Arknights: Endfield has excited longtime fans by bringing back one of the franchise’s most challenging endgame modes.

Players can increase battle difficulty through special modifiers that strengthen enemies or limit player abilities, encouraging strategic team-building and skill-based gameplay rather than relying on raw power. Its inclusion highlights Endfield’s growing focus on hardcore content and long-term replayability.

Beyond new story content and operators, Version 1.3 also introduces a large set of gameplay improvements aimed at reducing grind and streamlining progression.

Key additions include:
• Backup Power systems to prevent factory blackouts
• Automated recipe blockage handling
• Bulk artificing for gear crafting
• Weapon batch dismantling and lock management
• Improved enemy attack warnings
• Faster menu navigation for controller and keyboard users
• Revamped daily tasks for quicker completion

These updates suggest the developers are actively responding to player feedback about factory management friction and inventory clutter.

Online discussions surrounding the preview have been overwhelmingly positive. Fans on Reddit and gaming communities praised the darker narrative tone, the visual design of Sword Vault Dale, and the addition of fan-favorite mechanics like Contingency Contract.

Many players also highlighted how the update feels more ambitious than previous versions, with stronger connections to the wider Arknights universe and more cinematic storytelling.

The preview livestream itself generated significant attention across multiple gaming communities, especially due to the reveal of Mi Fu and Camille as headline operators.

With “Sketches of Lost Heirlooms,” Arknights: Endfield appears to be entering a major new phase. The combination of expanded lore, challenging endgame systems, visually stunning environments, and meaningful quality-of-life improvements demonstrates the developers’ commitment to evolving the game beyond its launch foundation.

For both longtime Arknights veterans and newer Endfield players, Version 1.3 could become one of the game’s most important updates yet.
