Subnautica 2 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, adaptive difficulty scaling, and peer-to-peer networking to enable multiple players to explore, build bases, and survive together in Subnautica 2's alien oceans.

Key Features:

• Deterministic Session Synchronization (DSS) for conflict-free shared world state
• Adaptive Dynamic Scaling that adjusts difficulty based on player count
• BepInEx IL2CPP-level hooking with hot-reloadable plugin architecture
• Shared inventory using Merkle tree verification
• Cross-platform multiplayer via NAT punch-through and WebRTC
• Session migration on host disconnect with zero data loss
