Details below were checked on November 6, 2026 against the Steam store page, Steam announcements and Gryphline’s official announcements. The latest version update named in them is [Sanctuary of Ink] (October 15, 2026). A newer notice does not confirm every older rule on this page, so each rule is dated. Confirm anything time-sensitive in the game or on the official page.

Arknights: Endfield is a free-to-play 3D game from Hypergryph, published by GRYPHLINE. It is set in the Arknights universe but is a separate game. This guide covers what it is, where you can play it, how accounts and servers work, and what to check before you install. The install steps and the performance checks are in two other guides on this site.

What Arknights: Endfield is

The Steam page describes Endfield as a 3D real-time strategy RPG. You play as the Endministrator of Endfield Industries, explore the planet Talos-II, and defend and expand the frontiers of human civilization.

Steam lists Hypergryph as the developer and GRYPHLINE as the publisher. Endfield is a separate game from the original Arknights, set in the same universe.

How combat works

Steam describes combat as leading your team into battle, moving them freely and chaining their skills to shatter enemy defenses. You control positioning during fights and use skills together rather than placing units on a fixed grid.

Exploration and the factory system

You explore Talos-II and develop regions as Endfield Industries expands. The official site describes the Automated Industry Complex (AIC) as enabling “the efficient automated production of various gear, explosives, batteries, tactical items, and other materials”. The beginner guide on this site covers the factory tutorials.

Where you can play

Gryphline’s pre-download notice of January 20, 2026 says Arknights: Endfield would officially release worldwide on January 22, 2026 at 11:00 AM (UTC+8) across all platforms. It lists PlayStation 5, PC, Android, iOS and the Epic Games Store.

Steam came later, and its dates must not be mixed up. The release date is the one shown on the Steam store page: October 14, 2026. Two announcements were published around it. Gryphline’s post, published October 14, 2026, gives the launch date as “after the [Sanctuary of Ink] version update on Oct. 15, 2026”. Steam’s own announcement “Arknights: Endfield Is Now Available on Steam” was published on October 15, 2026, the day the update launched. The notices read do not give a time zone for these dates, so this guide does not settle which day the Steam version went live.

Gryphline’s post says the Steam version uses the same game servers and account data as the other platforms. It also says the Steam version can be downloaded and updated only through the Steam client, not through the GRYPHLINK launcher.

Accounts and servers

You need a GRYPHLINE Account. The Steam page lists “GRYPHLINE Account (Supports Linking to Steam Account)” as a third-party account requirement. Gryphline’s PSN account FAQ of January 19, 2026 gives the sharing rules:

• Within the same server, account data is shared across PC, Android, iOS and PS5.
• Account data is not shared between different servers. Progress on the Americas / Europe servers is not shared with the Asia server. Gryphline’s Steam post of October 14, 2026 repeats this.
• On PS5 the game server is assigned from the region of your PSN account, and the FAQ says manual server selection is not currently supported.

PC system requirements

These are the requirements listed on the Steam store page. Both tiers list Windows 10 64-bit, DirectX 11, a broadband connection and 60 GB of available storage.

Minimum

• Processor: Intel Core i5-9400F
• Memory: 16 GB RAM
• Graphics: NVIDIA GeForce GTX 1060

Recommended

• Processor: Intel Core i7-10700K
• Memory: 16 GB RAM
• Graphics: NVIDIA GeForce RTX 2060

Gryphline’s January 2026 notice for the PC client lists its own figures, including 50 GB of free space plus 40 GB more while extracting files. These are two separate lists from two dates. The install guide on this site sets them side by side. Listed requirements describe what the developer expects the game to run on, not a guarantee of any frame rate.

Is it free to play?

Steam lists Arknights: Endfield as Free To Play. Check the in-game banner and purchase information for current rates and conditions, because these can change with updates.

What to check first

• Confirm your platform and server region before you start. Data is not shared between the Asia server and the Americas / Europe server.
• Create or link your GRYPHLINE Account. If you already have a character on another platform, use the same account.
• Compare your PC with the requirements of the store or launcher you use.
• Read the in-game tutorials for combat and factory basics before spending currency.

What this guide does not cover

• Install steps, launcher choices and the account-linking steps on Steam: the PC install guide covers them.
• Performance troubleshooting: the PC performance guide covers it.
• Anything after the notices of November 4, 2026. Updates, events and store pages change.
