RimWorld Odyssey Multiplayer Explained (1.6)
Written by Andrew Hammel
If you're hoping to play RimWorld Odyssey with friends, here's the reality: there is no working multiplayer support for version 1.6 as of July 2025. Everything multiplayer-related depends on community mods, and none of them are fully compatible with the Odyssey DLC yet.
No Official Multiplayer
RimWorld has never had official multiplayer. The only way to play with others is by using mods like Multiplayer (Zetrith fork) or Rimworld Together. These are the two main options, and both are broken with version 1.6.
Odyssey DLC Breaks Compatibility
The 1.6 update brings big changes to map generation, biomes, animals, weather, and more. Because of that, both major multiplayer mods are currently not compatible with Odyssey as of the writing of this article in July 2025.
Developers of those mods are working on updates, but there’s no public release or ETA. If you try to load Odyssey with multiplayer, it likely won't work or will crash immediately.
Your Multiplayer Options (On Version 1.5)
If you're okay downgrading to 1.5, you do have working options:
Multiplayer Mod (Zetrith / Zenith Fork)
Everyone plays in the same colony
All pawns, buildings, and events are shared
Best for co-op city building
Does not support separate factions
Rimworld Together
Each player starts their own colony on the world map
Time flows independently for each player
Interaction is limited, mostly trade or world events
Colonies can’t fully merge or join bases
Stability Notes
Multiplayer on 1.5 is playable, but there are still bugs. Desyncs happen sometimes, especially with large or untested mod lists.
Avoid performance-heavy mods like RocketMan
Use fewer than 30 mods if possible
Mods with a compatibility score of 4 are safe
Mods with a score of 1 should be removed
How to Downgrade to 1.5
To play multiplayer now, you’ll need to switch back to 1.5:
Right-click RimWorld in Steam
Go to Properties
Open the Betas tab
Select version 1.5 from the dropdown
Then install one of the supported multiplayer mods.
What About 1.6 Support?
Right now, multiplayer does not work on 1.6. That includes:
Odyssey DLC
New biomes
New weather
New map generation features
Mod developers are planning to update, but nothing is released yet. Expect a long wait if you want to use Odyssey in multiplayer.
Final Blurb
There’s no multiplayer support for RimWorld Odyssey or version 1.6 at this time. Your only option is to downgrade to version 1.5 and use community mods like Zetrith’s Multiplayer or Rimworld Together.
The community is working on updates behind the scenes, but for now, Odyssey is strictly single-player.
