Subnautica II Deep Synergy Co-op Mod

Skill by ara.so — Devtools Skills collection.

Overview

The Deep Synergy Multiplayer Mod transforms Subnautica 2 into a synchronized cooperative experience using BepInEx. It implements deterministic session synchronization, adaptive difficulty scaling based on player count, and peer-to-peer networking via WebRTC. The mod provides shared inventory management, cross-platform multiplayer, and optional AI-powered narrative generation.

Architecture:

• BepInEx 6.0+ plugin architecture (IL2CPP hooks)
• Peer-to-peer WebRTC data channels (no central server)
• Merkle tree-based inventory verification
• NAT punch-through for cross-platform connectivity
• Optional OpenAI/Claude API integration for dynamic narration
