Modern Warships Steam Cross-Progress Guide
Link mobile and PC correctly — wrong login choices can permanently split your roster.
Modern Warships runs on iOS, Android, and Steam (app ID 3144230), with cross-progress so captains can grind on phone and finish sessions on PC. That convenience collapses if you pick the wrong login on first launch — two separate Artstorm accounts with the same Steam name, mobile progress stranded, or duplicate purchases. Read this before clicking anything on the Steam welcome screen or linking from mobile settings.
Why login choice matters
Artstorm accounts anchor your ships, Gold, Battle Pass tiers, and clan membership. Steam is a distribution layer — not automatically your account identity. The game offers multiple entry paths:
- Artstorm / email / social login created on mobile first.
- Sign in with Steam on PC first launch.
- Link Steam from an existing mobile Artstorm account.
Mixing these without linking produces two rosters. Support may not merge them. Treat first login like a password manager moment — slow and deliberate.
Recommended path if you started on mobile
Already have months of mobile progress? This is the safe sequence:
- Install Modern Warships on Steam without creating a new Artstorm profile.
- On the login screen, choose Sign in with existing account (wording varies) — use the same Artstorm credentials as mobile.
- After confirming your ships and Gold appear, open Settings → Account → Link Steam if a separate link button exists.
- Verify one roster on both devices before spending Gold or starting Ship Upgrades.
Never “Sign in with Steam” as a new account if mobile progress must survive.
Recommended path if you start on Steam
PC-first players should:
- Decide whether mobile play is likely later.
- If yes, create or link an Artstorm account during Steam onboarding instead of anonymous Steam-only mode.
- Note your Artstorm email/password in a secure vault.
- On mobile install, log into that same Artstorm account — not a fresh guest profile.
Then configure Controls separately per device — settings do not sync, progress does.
Sign in with Steam pitfalls
The Sign in with Steam button is convenient and dangerous:
| Scenario | Risk |
|---|---|
| Steam first, no Artstorm link | Mobile later creates duplicate account |
| Mobile guest → Steam new account | Progress split across stores |
| Family shared Steam library | May not support same account rules — verify ToS |
| Reinstall and tap wrong button | Fresh empty roster looks like “data loss” |
If you open Steam, see a blank level-one roster, but mobile shows level fifty — you are logged into the wrong Artstorm identity. Log out completely and re-authenticate with original credentials.
Linking checklist
Before linking Steam to mobile progress:
- Screenshot your mobile player ID and ship count.
- Confirm email on Artstorm account.
- Log out of Steam client alt accounts if family-shared.
- Install latest patch on both platforms.
- Link on home Wi-Fi, not mid-match.
After linking:
- Ship count matches.
- Gold and Credits match.
- Battle Pass tier matches.
- Clan membership visible on both.
Mismatch? Stop purchasing until resolved.
Purchases and platforms
Steam wallet purchases may not appear on mobile store receipts and vice versa, but linked accounts share inventory once unified. Buying Gold on Steam while linked should reflect on phone after sync. If not, force-close app, relaunch, check mail tab — persistent issues need support tickets with both transaction IDs.
F2P players still benefit from linking — Codes redeem once per account regardless of device.
Offline mode and cross-progress
Offline mode works on both platforms. Offline earnings apply to the linked roster globally. Grind phone offline commutes, spend Credits on PC port screen — same account required.
Clan wars and social features
Clan Wars rosters tie to your Artstorm identity. Split accounts mean your clan sees the wrong ship list on PC. Officers boot duplicate profiles to prevent smurfing.
What does not sync
Typically per-device settings:
- Keybinds and sensitivity (Controls).
- Graphics quality presets.
- Download cache and replay files.
Gameplay advice still applies cross-platform — Missile and Flare Tactics on PC with mouse flares differs from touch, but rank and ships travel with the account.
Recovery if you already split accounts
Options are limited:
- Identify which account has the progress you want to keep.
- Contact Artstorm support with player IDs, receipts, and platform details.
- Abandon the empty duplicate — do not invest F2P Progression time twice.
Prevention beats tickets. Share this guide with clanmates before Steam migration waves.

Frequently Asked Questions
Quick answers to the most common questions.
Does Modern Warships support cross-progress between Steam and mobile?
Yes, when you link the same Artstorm account across platforms. Sign in with Steam as a new account without linking can create a separate roster with no shared progress.
I lost my ships on Steam — what happened?
You likely signed into a different Artstorm account than your mobile profile. Log out and sign in with the original Artstorm credentials used on phone.
Should I use Sign in with Steam or Artstorm login?
If you already have mobile progress, use your existing Artstorm login on Steam first, then link Steam. Do not create a fresh Steam-only account.
Do Steam purchases sync to mobile?
Linked accounts share inventory. Purchases on Steam should appear on mobile after sync. If not, relaunch the app and verify you are on the linked Artstorm account.
Can I merge two Modern Warships accounts?
Merging split accounts is not guaranteed. Contact official support with player IDs and receipts. Prevention by correct first login is far easier than recovery.
