Arknights: Endfield Cross-Save Guide — How to Sync Progress Across PC, PS5 & Mobile

Arknights: Endfield’s unified account system lets you play seamlessly across devices — PC, PlayStation 5, iOS, and Android — by syncing your progress under a single login. In this step-by-step guide, we’ll walk you through setting up cross-save, explain how it works, highlight common pitfalls, and share tips to make your multi-device experience smooth and stress-free.


What “Cross-Save” and “Cross-Platform Progression” Really Mean

Before diving into setup, it’s important to define the key terms:

  • Cross-Save (Cross-Progression): Your account progress — including story completion, operators, items, and unlocks — is stored server-side and accessible from any supported device when logged in with the same account.

  • Cross-Platform Play: While common in multiplayer titles, full cross-play between all devices hasn’t been explicitly documented yet. However, the game supports cross-progression as a core design.

In essence, you can continue your playthrough on different platforms without losing progress — a rare convenience for live service games.


Supported Platforms and Cross Progression Compatibility

Here’s how cross-save works with official supported platforms at launch:

Platform            Cross-Save Supported?Notes
PC (Windows)                                        Via official launcher/Epic Games Store
PlayStation 5Supported with the same Gryphline account
iOSContinued from other platforms
AndroidContinued from others
SteamNot supported at launch
Xbox / SwitchNot supported at launch

Arknights: Endfield’s supported platforms are confirmed to include PC, PS5, iOS, and Android at launch.

Note: While console storefronts like PlayStation may have platform-specific payment systems, your progress and unlocked content will sync as long as you log in with the same core account across devices.


Step-by-Step Setup — Link Your Account for Cross-Save

Arknights: Endfield Cross-Save Guide

To ensure your progress syncs across all platforms, follow these core steps:

1. Create & Pre-Register With a Unified Account

Use the official pre-registration website or any platform login with:

  • Email

  • Apple ID

  • Google account

  • Connected social account

Make sure to include all platforms you plan to use during the pre-registration step.

2. Pre-Load the Game Before Launch

For platforms like PC and PS5, downloading ahead of launch ensures you’re ready at 09:00 GMT+8 on January 22, 2026.

Pro Tip: Pre-loading saves time and helps you start syncing progress immediately on launch day.

3. Log In with the Exact Same Credentials

When you first launch Endfield on any supported device:

  • Choose Existing Account

  • Enter the same email/social login you used during pre-registration
    If you accidentally create a new account, your progress will not sync.


Common Cross-Save Troubleshooting

Even with the system designed to make syncing easy, some issues can crop up:

❗ Wrong Account on First Login

If you log in with a platform store account (e.g., PSN) before linking a Gryphline/global account, you might create a new save file instead of syncing progress.
Fix:

  1. Log out

  2. Relaunch and select “Existing Account”

  3. Use your pre-registered email login

❗ Multiple Login Credentials

If you used different emails or login methods across devices, your progress may fragment.
Fix: Link your account in-game to a single email address. (Similar cross-save in other games like Honkai Star Rail recommends email linking first.)

❗ Device Recognition Errors

Community testers reported occasional device recognition errors (e.g., after OS changes), but logging out and back in usually resolves it.


Pro Tips for a Seamless Cross-Platform Experience

💡 Claim Rewards on Your Main Device First
Pre-registration milestone rewards — including operators and items — are delivered in-game mail. Claim them on the device you play most.

💡 Link Early
Do account linking before launch so you don’t risk creating multiple accounts across platforms.

💡 Be Mindful of In-App Purchases
Premium purchases might be tied to platform storefronts. While progress syncs, purchase availability can differ across PSN, mobile stores, or PC launcher environments.

💡 Use Same Email / Social Login
Consistency is key — always use the same login method across devices to avoid mismatched progress.


Cross-Save vs Cross-Play — What’s Supported?

  • Cross-Save / Cross-Progression: Official support confirmed across PC, PS5, iOS, and Android.

  • 🔄 Cross-Play (Multiplayer): Details are less clear and not confirmed in full. Some sources suggest cooperative features may be cross-platform, but specifics remain limited.

For now, prioritize how your progress syncs across devices — that’s the main confirmed feature.


FAQ — Quick Answers for Cross-Save Questions

Q: Can I play on PS5 then continue on my phone?

A: Yes — as long as you log into the same account on both devices.

Q: Does cross-save work for purchases?

A: Progress syncs, but in-app purchases may be tied to the platform store you bought them on and may not transfer automatically.

Q: What if I logged into a new account by mistake on PS5?

A: Log out and re-login with your pre-registered account. Avoid creating a new account in the game.

Q: Do I need to link anything before playing?

A: Linking your account to an email or third-party login during pre-registration ensures smooth syncing.

Q: Will progress sync between beta and full launch?

A: Beta tests use wipes; progress won’t carry over. The cross-save system applies to launch version progress.
