The short answer
Yes. Dimraeth supports online co-op for up to eight players, and you can also play solo. The eight-player total includes the host.
Hosting and local co-op
The developer’s September 2026 Early Access FAQ confirms peer-to-peer co-op: one player hosts the game. Dedicated servers and couch co-op are not supported for Early Access.
Developer Early Access FAQ ↗Progress that travels with your character
Your hero’s level, equipment, inventory, spells and personal progression travel with the character between worlds.
Progress that stays in the world
Story progress, recruited allies and buildings stay with the world where they were earned or built.
Steam store ↗Planning a shared adventure
If you want to follow one shared story with friends, agree on the world you will return to. This is a practical suggestion based on the documented world-progress rules.
Use the official Discord to find other players and check the developer’s news for changes. This guide does not claim to document tested host or join menu steps.
Modded characters and multiplayer
This is not a Steam Workshop or “best mods” guide. Official patch notes state a specific join rule.
Release 0.107.7745 says, verbatim:
Characters which have been modded beyond the game's limits are rejected from multiplayer worlds
Label: Official (Mudtek · Release 0.107.7745).
That sentence does not say every file change is blocked, and it does not say every single-player change is allowed. It only confirms rejection of characters modded beyond the game's limits when joining multiplayer worlds. The same notes also destroy unobtainable equipment wherever it lands.
Release 0.107.7779 adds, under Joining / multiplayer:
Host gets a chat alert on a client-side cheat attempt
Label: Official (Mudtek · Release 0.107.7779).
As of this update, this guide has not found an official Steam Workshop support announcement for Dimraeth. Prefer Steam announcements over third-party trainer pages when deciding what the game currently enforces.
Character progression can still move between worlds while story and buildings stay with a world—see the sections above. A rejected join is a different rule from “progress does not share.”

Source dates and evidence limits are listed below. Launch announcements establish availability. Older design descriptions provide context; they do not verify current skill values or balance.
As checked on September 17, 2026, the official website FAQ still contains pre-launch wording about release timing and the demo. For release status and the current Early Access content, use the Steam store and Mudtek’s Steam announcements. Hosting details in this guide use the developer’s September 2026 Early Access FAQ.
