SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you turn Subnautica 2’s single-player gameplay into a synchronized cooperative multiplayer experience, preventing world-state and inventory desync between players.

Core Features & Use Cases

  • Synchronized session state: Keeps world state consistent across clients using Merkle tree inventory tracking.
  • Peer-to-peer networking: Uses WebRTC with NAT punch-through to reduce reliance on centralized servers.
  • Configurable gameplay scaling: Applies adaptive difficulty and resource/oxygen tuning per session profile.
  • Optional AI narrative hooks: Integrates OpenAI/Claude-style API calls for in-game story and lore generation.
  • Host-driven session controls and debugging: Provides console commands for hosting, joining, status checks, resync, and conflict debugging.

Quick Start

Install BepInEx into your Subnautica 2 root, place the Deep Synergy plugin DLLs into BepInEx/plugins, then launch the game and start a session with /start_server.

How does state synchronization prevent inventory desync in multiplayer?▼

State synchronization prevents inventory desync in multiplayer by using Merkle tree inventory tracking to consistently keep world state and player data synchronized across all connected clients.

Can I configure gameplay scaling and difficulty for a multiplayer session?▼

You can configure gameplay scaling and adaptive difficulty by editing the synergy_profile.json file, which allows you to tune resource and oxygen settings per multiplayer session profile.

Do I need an OpenAI or Claude API key for the AI narrative features?▼

Yes, utilizing the optional AI-assisted narrative generation requires environment-variable-based API integration to connect your OpenAI or Claude credentials for in-game story and lore creation.

What commands are available for debugging session state in multiplayer?▼

Host-driven session controls provide console commands for checking session status, joining, hosting, triggering resync operations, and debugging world-state conflicts during multiplayer gameplay.
