Subnautica II Deep Synergy Multiplayer Mod

Skill by ara.so — Devtools Skills collection.

Overview

The Deep Synergy Multiplayer Mod transforms Subnautica 2 into a synchronized cooperative experience using the BepInEx modding framework. It implements deterministic session synchronization (DSS), adaptive dynamic scaling (ADS), and peer-to-peer connectivity via WebRTC for seamless multiplayer gameplay.

Key Architecture:

• BepInEx Plugin - Hooks into Unity IL2CPP runtime without modifying game files
• Decentralized Session Management - No central servers; uses NAT punch-through
• Merkle Tree Inventory - Blockchain-inspired state verification across peers
• Adaptive Scaling - Creature spawns and resource availability adjust to player count
