Short answer: Dimraeth is a 1–8 player co-op RPG with seamless drop-in/drop-out. It runs peer-to-peer, so one player hosts. There is no split-screen and it is not an MMO. Your hero travels between worlds; the world itself does not.
What the store page promises
The clearest statement of the co-op design is on the store page itself, and it is unusually precise about progression.
Official Steam store page
“Play alone or in seamless drop-in/drop-out co-op for up to eight players. Your hero's level, equipment, inventory, spells, and personal progression travel between worlds, while story progress, recruited allies, and buildings remain tied to each world.”
“Explore a handcrafted pixel-art fantasy world alone or with up to seven other players in seamless drop-in/drop-out co-op.”

That split sentence is the single most useful thing on this page, so it is worth separating into its two halves.
| Travels with your hero | Stays with the world |
|---|---|
| Level | Story progress |
| Equipment | Recruited allies |
| Inventory | Buildings |
| Spells | — |
| Personal progression | — |
The practical consequence is that you can take a developed character into a friend’s fresh world and be powerful there, but you will not be able to hand that friend your quest progress, your Sanctum roster or your base. Building a settlement is a per-world project.
This also means the reverse is true. If you join someone else’s world, you are a guest in their story: their quest state, their NPCs and their buildings are what you will see, regardless of how far you have progressed in your own game.
How the connection works
The store page does not describe hosting. The website FAQ does, and it is direct.
Official Website FAQ
Can I host a dedicated server? “Not at this time. Dimraeth uses a peer-to-peer system for co-op play. That means one player acts as the host when you start a game with friends. We don't currently support dedicated or private servers.”
Does Dimraeth support local multiplayer? “Not at the moment. Dimraeth supports online co-op, but doesn't offer local or split-screen multiplayer.”
Is Dimraeth an MMO? “Nope! Dimraeth is not an MMO. It's a co-op RPG designed for small groups of players (up to 8). You can play solo or with friends, but you won't see hundreds of random players running around.”

Three practical points follow.
Hosting is a player’s job. With peer-to-peer and no dedicated servers, one machine carries the session. If the host leaves, the session ends — that is what peer-to-peer means here, though Mudtek has not described what happens to the world state in that case.
No couch co-op. Split-screen and local multiplayer are explicitly ruled out. Every player needs their own copy and their own machine on the same network of connected players.
Small group by design. The MMO answer is not a technicality. Mudtek distinguishes Dimraeth from MMOs on the grounds of group size and shared space, not on server architecture.
Recommended party size
The store page says up to eight. Mudtek’s own playtest guidance was more conservative.
Official Playtest summary, 19 September 2025
“Both single-player and multiplayer are fully functional. This is a co-op ARPG, not an MMO, we recommend 1–4 players for the best experience, but you can play with up to 8 or higher if you wish.”
Source: Mudtek Steam announcement, 19 September 2025
That statement carries two cautions. It is from the September 2025 playtest rather than the launched build, and its “1–4 players” recommendation is a design opinion rather than a limit. The number that has held steady across sources is eight: the store page, the website header (“Dimraeth – A 1-8 Player Co-op Fantasy RPG”) and the September 2026 content update all use it.
Note Eight versus “8 or higher”
The 2025 playtest post said “up to 8 or higher if you wish”, while every later official source caps the number at eight. Treat eight as the supported figure. The earlier phrasing predates the launch build's multiplayer lobby rework.

Playing solo
Dimraeth is fully playable alone. The website FAQ answers the question without hedging: “Sure! Dimraeth can be played solo from start to finish.”
Nothing in the co-op design suggests a penalty for playing alone. The achievement completion rates, which track a player base that includes many solo players, show a normal progression curve through the main story. There are no achievements that reference grouping.
If you have no group. Mudtek points players at a looking-for-group channel on their Discord for finding co-op partners. That is the studio's own suggested route rather than an in-game matchmaker.
Where co-op changes the game
Two systems are explicitly designed around having other players. Food and potions are the first.
Official Design post, 20 January 2026
“Potions also become a co-op tool. Some potions can be thrown, meaning if your friend is in trouble, you can literally throw them a heal mid-fight. In co-op, this creates those small save moments that stop a run from collapsing: a teammate gets clipped, their health drops, and instead of backing off and letting the fight spiral, you land a thrown potion and keep the team's momentum intact.”

The second is combat tempo. The combat system is built on stamina management and reading enemy telegraphs, which means a group can cover a wider set of problems than one player can — but the food and potion loop is the one Mudtek describes in explicitly co-operative terms.
For the consumable side of that loop, see the potions page. For how co-op interacts with the base you build, see the base building page.
