Map, platform and update differences are noted where they affect the steps.
Medieval Dynasty supports online crossplay on the Oxbow across supported PC versions, PlayStation 5 and Xbox Series X|S. A co-op session allows four players in total, including the host, and the host saves the shared game. The Valley remains single-player, so choose or open an Oxbow campaign when you want to play together.
Check the supported crossplay scope
Crossplay lets players on supported platforms join the same online Oxbow session. The developer FAQ and the publisher's current-generation console announcement establish the scope summarized below. Check your exact game and platform before applying these details to a group member's installation.
| Platform or feature | Reviewed status | Practical meaning |
|---|---|---|
| Supported PC versions | Online Oxbow co-op and crossplay supported | Check that you are using the original game and its current multiplayer options |
| PlayStation 5 | Included in modern console co-op scope | Oxbow online play is covered by the reviewed guidance |
| Xbox Series X|S | Included in modern console co-op scope | Oxbow online play is covered by the reviewed guidance |
| PlayStation 4 / Xbox One | Outside this current-generation co-op scope | Do not apply PS5 or Series instructions automatically |
| Cross-platform save transfer | Not established by the reviewed sources | Crossplay support is not a promise of transferable saves |
Use the Oxbow for a shared campaign
The Oxbow supports both solo play and online co-op, while the Valley is a single-player map. Their stories and playable zones are separate, so you cannot walk from a Valley campaign into the Oxbow to meet friends. Check the campaign map before spending time looking for multiplayer options that belong to a different save.
If your group is beginning together, agree on an Oxbow campaign before planning a shared village. If one person already has a settlement, confirm which map that save uses and whether everyone wants to join it. Our map comparison explains the choice if you are still deciding where to begin.
Include the host in the four-player count
The co-op limit is four players altogether, rather than four guests in addition to a host. Plan for the host and the remaining group members within that total. This avoids arranging a session on the assumption that five people can occupy the same shared game.
Players share a village, so discuss how you want to divide the next few jobs. One person might plan a building while another gathers materials, but that is an organizational suggestion rather than a required character-role system. Agreeing on immediate priorities is especially helpful when several people join a village that one player has already developed.
Choose the host with saving and availability in mind
The host saves the game, and the online session ends when that host leaves. Choose someone whose availability fits the people who expect to keep returning to the campaign. A shared settlement is easier to schedule when everyone understands who must be present for the session to run.
The developer FAQ also places world customization and player permissions under the host's control. Discuss the intended settings and permissions before beginning a long building project together. These decisions concern the current shared game and should not be treated as evidence that each participant receives an independently portable copy of its save.
Open an existing solo Oxbow save online
The official FAQ confirms that an Oxbow campaign started alone can be opened online later. You can therefore begin learning the game without waiting for the whole group to be available. Confirm that the existing campaign is an Oxbow save before inviting friends to join your settlement.
This option does not turn a Valley save into an Oxbow campaign. Map selection and online-session access are different decisions, even though both affect how your group plays. Keep track of the relevant save and explain its current progress so that joining players know which village they are entering.
Expect online play rather than LAN or split screen
The developer FAQ describes co-op as online play and rules out LAN, split screen and dedicated servers. Two people sharing a room should therefore not assume that one screen or a local-network-only arrangement provides the supported co-op mode. Each group should plan around the online options available in its supported installations.
The lack of dedicated servers also matters when deciding whether a village can stay available without its usual host. The reviewed model is a hosted session that closes when the host leaves. Arrange future play around that availability rather than expecting a separately running server to preserve continuous access for everyone.
Prepare the group before starting the session
Ask each player to confirm the original Medieval Dynasty game, their platform and access to the current Oxbow multiplayer menus. For console players, check the platform's current online-service requirements rather than relying on an old subscription name or price. These basic checks establish whether everyone is trying to use the same supported type of play.
Then agree who will host, which save will be used and what the first shared objective will be. A new group can use our beginner guide to choose a manageable building and resource plan. A returning group benefits from a short check of available supplies and pending seasonal work before starting several competing projects.
Keep crossplay separate from save migration
Crossplay support answers whether compatible players can join the same online session across the supported platforms. It does not, by itself, answer whether a saved campaign can be transferred from one platform or account to another. The reviewed sources do not establish a general cross-platform save-migration procedure, so this guide does not invent one.
Use the host-saving rule when planning continuity for the group's existing village. If changing host or platform is essential to your plan, seek a current official answer for that exact situation before relying on a transfer. Avoid deleting or replacing a working save based only on the fact that online crossplay exists.
Narrow down joining problems before guessing at fixes
If someone cannot join, first identify the campaign map, exact platform and game edition involved. Confirm the group size and whether the intended host still has the session open. These checks can reveal a mismatch in the planned setup without claiming that one generic workaround fixes every connection problem.
For a problem that remains, record the actual message shown and consult current official support or the developer's community resources. This page does not supply unverified error-code remedies, router changes or promises about platform-specific failures. Describing the exact situation gives a support discussion a clearer starting point than repeating advice intended for another edition.
Read the source dates alongside the feature list
The developer FAQ used here was last edited on June 26, 2025, and the publisher's modern-console co-op announcement is dated June 27, 2024. The Steam store provides the original game's product and map context. These official sources were reviewed for this page on October 20, 2026, rather than presented as a new multiplayer test on every platform.
Use the current game menus and later official announcements if the supported options change. The practical starting point remains an online Oxbow session, a compatible group of up to four people and an available host. Set those expectations before investing time in the shared settlement so that the group's campaign fits how everyone plans to play.
