ATLYSS has an active community mod scene centered on Thunderstore. Mods are not the same as Steam Workshop items: as of this update, ATLYSS does not expose an official Steam Workshop, so most players use r2modman, Gale or Thunderstore Mod Manager with BepInEx (Mono).
Recommended Installation Method
- Install r2modman or Thunderstore Mod Manager from their official GitHub / Overwolf releases.
- Select ATLYSS in the game list and create a new profile.
- Install the manager-recommended BepInExPack (Mono edition); dependencies resolve automatically.
- Add mods one at a time, checking their version compatibility.
- Launch via Start Modded. When troubleshooting issues or crashes, use Start Vanilla.
Profile-based managers keep mod files separate from your core Steam installation and allow instant toggling of packages after game patches.
Top Popular ATLYSS Mods on Thunderstore
- Homebrewery: The cornerstone framework mod for content creators. Allows adding custom character parts, expanding body slider limits, camera controls (freecam), and injecting custom gear and textures.
- Atlyss Emote Wheel (by SnivyXXY): Adds a functional radial emote wheel UI and custom animation pack support.
- EasyVanity (by WatchingPotatoes): Removes transmog restrictions and allows free, unrestricted appearance customization.
- ModAudio (by Marioalexsan): Lets players swap default soundscapes and background music with custom audio tracks.
- Haversack of Everything / Asset Packs: Massive community packs providing hundreds of vanity items, shields, capes, and weapon skins commonly required by multiplayer RP servers.
- Character Freedom (by portalsam): Unlocks character creation sliders beyond vanilla limits (other players need matching packages to view custom proportions).
Multiplayer Servers & Profile Codes
When joining modded community lobbies or dedicated servers:
- Mod managers allow you to export and import Profile Codes (a short string that mirrors the host's exact mod list and package versions).
- Make sure all players in a dungeon party have matching version profiles to avoid desynchronization or invisible assets.
Compatibility with 2026 Updates (12026.a1–a3)
The 12026 update overhauled status effect durations, netcode animations, and UI mesh structures:
- Always update BepInEx and mods to their latest 2026 releases before reporting bugs.
- If UI elements or chat boxes glitch, disable outdated HUD mods first.
- Keep a clean vanilla profile ready to verify whether an issue is a base game bug or a mod conflict.
Steam Deck & Linux
r2modman provides native Linux AppImage and Flatpak builds. After configuring your profile in Desktop Mode, copy the generated launch string into Steam's Launch Options for seamless Game Mode execution.
Mods vs Save Editors
A save editor edits local profile data in ATLYSS_Data/profileCollections; it is not a BepInEx mod. Always create a full backup of this folder and disable Steam Cloud before editing. Consult the ATLYSS Save Editor Guide.
Safety Checklist
- Back up saves before installing or updating mods.
- Prefer manager profiles over manual DLL copying.
- Check last-updated dates after every ATLYSS patch.
- Do not use item-spawn or cheat functions to disrupt public multiplayer.
- Keep a clean vanilla profile for support and bug reports.
