Heroes of Might and Magic III Remake Cross-Play and Cross-Save for Heroes III Remake

Cross-play and cross-save are two different questions for Heroes of Might and Magic III Remake. Cross-play asks whether a PlayStation 5 player can join an Xbox player in a Hot Seat or online lobby. Cross-save asks whether the cloud-save on one console can be loaded on a PC. The wiki keeps the two answers separate because Ubisoft has signalled the first is uncertain and the second is essentially a Ubisoft+ feature.

What is confirmed about cross-play

The August 2026 Welcome Back to Erathia blog named six storefronts: Steam, Ubisoft Store, Epic, PlayStation 5, Xbox Series, Ubisoft+. It named eight-player online and Hot Seat. It did not name cross-play between PlayStation 5 and Xbox. For a Ubisoft strategy remake, the launch-day pattern tends to be:

• PC-to-PC cross-play across the three PC storefronts (Steam, Ubisoft Store, Epic).
• Console parity, meaning PlayStation 5 plays only with PlayStation 5 and Xbox plays only with Xbox.
• Optional platform-pooled matchmaking added in a post-launch patch.

That is a pattern, not a promise. Treat it as the most likely shape until Ubisoft says otherwise.

What is confirmed about cross-save

Ubisoft+ is Ubisoft’s subscription service and it ships with cloud saves that move between the platforms Ubisoft+ is available on. Heroes III Remake is listed as a Ubisoft+ day-one title. If you buy a Ubisoft+ month and play on PC, your campaign saves should appear in your PS5 and Xbox Ubisoft+ clients on the same account.

For non-Ubisoft+ owners, the cross-save question is more limited:

• PlayStation 5 to PS5: cloud saves through PS Plus, if PS Plus is the publisher’s choice. Ubisoft has not signalled either way.
• Xbox Series to Xbox Series: cloud saves through Xbox Live, if Xbox Live is the publisher’s choice. Ubisoft has not signalled either way.
• Steam to Steam: cloud saves through Steam Cloud, if Steam Cloud is enabled in the app settings. Steam app 3809850 currently does not show cloud save settings publicly.

For Hot Seat, the save lives on the device where the game ran. A Hot Seat campaign started on PS5 stays on PS5 unless an explicit export-import flow ships in the menu. The multiplayer page covers the practical workarounds.

Why cross-play matters for Heroes III specifically

Heroes III is a slow-paced turn-based game with multiplayer lobbies that historically have struggled to fill. Eight-player cross-platform would let a US PS5 player team with an EU PC player for the same lobby. That is a quiet, large improvement on what the original Complete Edition’s GameRanger and direct-IP lobbies could do.

For Hot Seat, cross-play is irrelevant: Hot Seat is local players sharing one screen or one input. For online, cross-play matters because it expands the lobby pool.

How matchmaking might handle cross-play

Even if cross-play is enabled, Ubisoft typically segregates ranked matchmaking by input method (mouse-and-keyboard vs controller) and by region. The multiplayer page notes that simultaneous turns is confirmed; whether cross-play is confirmed for ranked is not.

If you care about ranked ladders and your input is a controller, a console may be the friendlier home for the first three to six months. If you only play unranked or with friends, the platform matters less than the friends list.

Cloud save and UGC

The community maps and map editor ship with an UGC hub, and the UGC hub depends on a Ubisoft account. The hub lets you upload maps and download other people’s maps. Cross-save for UGC is not yet confirmed as a feature. The map editor page covers the .h3m format that the remake will preserve for old custom maps, which is the legacy path independent of cloud save.

How to follow cross-play announcements

The fastest feed for cross-play confirmations is the Ubisoft news mirror on the official links page. Press releases on the Ubisoft news channel and Steam news posts on app 3809850 will announce platform-pooled matchmaking before it goes live. The wiki will mirror any platform-pooled match note in the multiplayer page within a day of a public post.

Until then, this page is the bookmark for the day the PS5/Xbox parity breaks.
