SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps players set up a cooperative multiplayer experience for Subnautica 2 by installing and configuring the Deep Synergy mod so sessions, inventory, and gameplay state stay synchronized across peers.

Core Features & Use Cases

BepInEx IL2CPP Mod Installation: Installs the BepInEx-based plugin into the correct game directory so the mod loads without modifying core game files.
Synchronized Session & State Management: Uses decentralized session management (peer-to-peer) and deterministic session synchronization to keep gameplay aligned.
Shared Gameplay State: Synchronizes inventory with Merkle-hash style integrity verification and supports shared blueprints, ping sharing, and time-of-day sync.

Quick Start

Install the Deep Synergy mod by placing its files into Subnautica 2’s BepInEx/plugins/ directory, then create and configure BepInEx/config/synergy_profile.json before launching the game to start hosting with /start_server.

FAQPage Schema

How do I set up a Subnautica 2 multiplayer co-op session using BepInEx?▼

To set up Subnautica 2 multiplayer, install BepInEx IL2CPP, deploy the Deep Synergy mod DLLs into the BepInEx/plugins directory, and generate a synergy_profile.json configuration file before launching the game to host a peer-to-peer session.

How does the Deep Synergy mod handle inventory syncing and state synchronization across peers?▼

Inventory syncing in Deep Synergy uses Merkle-hash style integrity verification to ensure state synchronization across peers, while deterministic session management keeps shared blueprints, ping sharing, and time-of-day gameplay aligned.

Do I need WebRTC configuration for peer-to-peer Subnautica 2 multiplayer sessions?▼

Yes, WebRTC configuration is required to establish decentralized peer-to-peer session joining and networking, which is defined alongside adaptive scaling and shared gameplay rules in the synergy_profile.json file.

How do I troubleshoot mod load or desync issues in a Subnautica 2 co-op session?▼

Troubleshooting desync issues involves verifying the BepInEx IL2CPP installation, checking that mod DLLs are correctly placed in BepInEx/plugins, and ensuring the synergy_profile.json network parameters match across all peers.

Can I configure shared gameplay rules and adaptive scaling for Subnautica 2 multiplayer?▼

Yes, shared gameplay rules and adaptive scaling are configured within the synergy_profile.json file, allowing hosts to define synchronized parameters for time-of-day, blueprints, and peer-to-peer state management.

Why does my Subnautica 2 multiplayer mod fail to load after installation?▼

Mod load failures occur when BepInEx IL2CPP is missing or DLLs are not deployed into the correct BepInEx/plugins directory, preventing the Deep Synergy mod from initializing without modifying core game files.
