VERSION HISTORY
Game updates, patches & platform versions
About this version log
This is a live record of every Arknights: Endfield version release, including download size, on-disk size, patch deltas, and per-platform resource versions for Windows, Android, iOS, and PlayStation. Data is auto-synced from the open-source ak-endfield-api-archive, which pulls directly from Hypergryph's official CDN — so timing reflects what actually shipped, not what was announced.
Use this page to plan downloads (patch days can hit a few GB), to check whether a cross-platform asset rollout has reached your platform, or to look up which version introduced a specific feature. The launcher version is tracked separately because launcher updates are not always coupled to game-data updates. Click any version entry in the timeline to see the platform-by-platform resource breakdown for that release.

Frequently Asked Questions
How often does Arknights: Endfield release new versions?
Major versions land roughly every 6 weeks, following Hypergryph's standard patch cadence inherited from Arknights mobile. Each major version (e.g., 1.1, 1.2) introduces a new story chapter, two limited operator banners, a major event, and balance changes. Minor patches (1.2.1, 1.2.2) ship every 1–2 weeks within a major version to push hotfixes, smaller events, and content additions. Resource-only updates (no client patch) happen even more frequently — sometimes weekly — for daily event rotations and store updates.
Why are there separate platform resource versions?
Each platform (Windows, Android, iOS, PlayStation) ships independently because each platform has its own store certification timeline. Windows and Android usually update first because they use server-driven hot patches; iOS waits on App Store review (usually 12–48 hours); PlayStation goes through Sony certification which can take several days. The 'resource version' string identifies the exact asset bundle each platform has loaded — players on the same major version but different platforms may briefly have mismatched assets during a rollout.
What is the difference between packed size and unpacked size?
Packed size is the download — what your device pulls over the network as compressed asset bundles. Unpacked size is the storage cost after the client extracts and processes the bundles into runtime form. The ratio is typically 1.5x–2x, so a 4GB download can use 8GB on disk. Patch sizes are usually packed only because patches deliver delta updates that decompress in place. Always have headroom equal to packed + unpacked size before starting a major update, otherwise the install fails midway.
Can I downgrade to an earlier version?
Not officially. Arknights: Endfield is a live-service game with server-side authority — your account state expects the current version's game data, so an older client would refuse to connect to the live servers. Even archived APK builds from the source data archive cannot be used to play; they exist for data preservation and reverse engineering, not gameplay. If a new patch introduces a bug that breaks your build, the only fix is to wait for a hotfix; rolling back is not a supported recovery path.
Where does the version data come from?
Version history is sourced from the open-source ak-endfield-api-archive project by daydreamer-json, which scrapes the official Hypergryph CDN endpoints and version manifests at regular intervals. Because the data comes directly from the game's own update infrastructure, it reflects actual release timing — not announcement timing or community speculation. The archive also captures cross-platform resource versions, patch deltas, and launcher build numbers, so you can see exactly what shipped to which platform when.
