MycoRelic is balanced for 3 to 4 players in online co-op, and that is the party size Sandy Dingo Games recommends. The technical limit is far higher, 64 players, but the developer says that is “obviously not recommended.” You can also play the whole game solo, offline.
Co-op is drop-in and peer to peer, with your own character traveling between worlds. Here is how it works at the 1.0 release, which arrived on Steam on November 11, 2026.
The Player Limit and the Recommended Party
Asked on the Steam forums how many people can play together, a developer at Sandy Dingo Games answered: “The technical limit is 64, but that’s obviously not recommended. The game is balanced for 3-4 players.”
There are two reasons to stay near that number:
- Balance. Bosses and encounters are tuned around a small group. Some fights scale with the party, such as the Water Temple’s Guardians of Rain and Storm, which the developer reworked to scale with player count, but the game as a whole is built for three or four.
- The host’s PC. Multiplayer is peer to peer, so there is no dedicated server. The host’s computer runs the world, and the more players join, the more load falls on the host’s CPU.
So two players is a comfortable duo, three or four is the intended experience, and anything past that is at your own risk.
How to Host and Join a Co-op Game
MycoRelic’s official FAQ and patch notes describe two ways in:
- Host World. Click Host World on the main menu to open your world, then invite friends through Steam’s built-in friends list.
- Join codes. Hosting a game automatically generates a short code. Share it, and other players can join you without being friends on Steam. Join codes arrived in the September 2026 update.
On Steam Deck, the on-screen keyboard opens for the join code field, and it works with taps, buttons and Big Picture mode.
A few things make playing together smoother once you are in:
- Relic Blooms are the checkpoints. Inside one you can save, edit your stats and swap body parts, and summon your friends to your location.
- Dusk teleport pads move the whole party at once.
- A sound plays for everyone when a new player joins the session.
Your Character Comes With You
Characters are saved locally on your own PC, not inside the host’s world. The official FAQ says you can bring your character “around into other worlds hosted by friends,” and the store page adds that you join with your character and items. Build your fungus robot in your own world, then take it into a friend’s game.
To protect those characters, the game backs up your save when it launches and then every minute. The update that added the backups followed save losses in multiplayer during Early Access.
Solo Play, PvP and Platforms
- Solo: fully supported. The FAQ says the game “can also be played offline in singleplayer for those who want a solo experience.”
- PvP: a toggle in the menu, off by default. Players need PvP enabled to damage each other.
- Split screen: not supported. Steam lists online co-op only.
- Platforms: PC only, on Steam for Windows. There is no console version, so there is no crossplay to worry about.
- Controllers: Steam lists full controller support, including DualShock and DualSense.
Is MycoRelic Better With Friends?
The developer has described MycoRelic as a soulslike with drop-in co-op, and the FAQ says it was “built from the ground up with online cooperation in mind.” That said, solo is fully supported, and one of the developers recently finished the whole game alone.
