SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the difficulty of installing and configuring a synchronized multiplayer co-op setup for Subnautica 2 so multiple players can share consistent world state without desync.

Core Features & Use Cases

Deterministic session synchronization (DSS): Keeps inventory, base-building, and creature behavior aligned across clients using state hashing and verification intervals.
Peer-to-peer WebRTC connectivity: Enables NAT punch-through style connectivity with configurable latency/packet-loss tolerances for smoother co-op sessions.
Optional AI narrative integration: Lets you generate contextual in-game journal entries and species lore via OpenAI/Claude integrations (when enabled).

Use Case: Host a Deep Synergy co-op session for a group of friends to explore together with consistent loot, blueprint placement, and creature behavior while also optionally generating PDA journal narration.

Quick Start

Ask: "Using the Deep Synergy skill, create a synergy_profile.json for a 4-player adaptive co-op session, then walk me through hosting and joining via the BepInEx console commands."

FAQPage Schema

How do I set up deterministic multiplayer co-op for Subnautica 2 without desync?▼

To set up deterministic Subnautica 2 multiplayer co-op without desync, configure the Deep Synergy BepInEx mod to enable state hashing and synchronization for inventory, base-building, and creature behavior across clients.

How does Subnautica 2 co-op session synchronization handle inventory integrity?▼

Subnautica 2 co-op session synchronization handles inventory integrity by using Merkle-style state hashing and verification intervals to keep loot, blueprint placement, and creature behavior perfectly aligned across all connected clients.

Can I use WebRTC peer-to-peer connectivity for Subnautica 2 multiplayer?▼

Yes, you can use WebRTC peer-to-peer connectivity for Subnautica 2 multiplayer to enable NAT punch-through style connections with configurable latency and packet-loss tolerances for smoother co-op sessions.

Do I need BepInEx to install the Subnautica 2 Deep Synergy mod?▼

Yes, you need BepInEx 6.0.x IL2CPP installed to use the Deep Synergy mod, placing the plugin files correctly under Subnautica2/BepInEx/plugins/DeepSynergy/ and provisioning the synergy_profile.json configuration file.

Why does my Subnautica 2 co-op session keep experiencing world desync?▼

Your Subnautica 2 co-op session desync occurs when the Deep Synergy DSS synchronization settings are mismatched, requiring identical synergy_profile.json and matching session configurations across all players to maintain a consistent world state.

Does the Subnautica 2 Deep Synergy mod support AI narrative features?▼

Yes, the Deep Synergy mod supports optional AI narrative features using OpenAI and Claude integrations to generate contextual in-game PDA journal entries and species lore output when enabled in the configuration.
