Subnautica 2 Deep Synergy Coop Mod

Skill by ara.so — Devtools Skills collection.

Overview

Deep Synergy is a BepInEx-based cooperative multiplayer modification for Subnautica 2 that transforms the single-player survival experience into a synchronized multi-player session. The mod implements deterministic session synchronization (DSS), adaptive dynamic scaling (ADS), and decentralized peer-to-peer networking to enable seamless co-op gameplay without central server infrastructure.

Key Capabilities:

• Synchronized world state across multiple clients using Merkle tree inventory tracking
• WebRTC-based peer-to-peer networking with NAT punch-through
• Hot-reloadable BepInEx plugin architecture (IL2CPP hooks)
• Optional OpenAI/Claude API integration for dynamic narrative generation
• Cross-platform support (Windows, macOS, Linux/Steam Deck)
• Adaptive difficulty scaling based on player count
