What It Does

The Deep Synergy Multiplayer Mod transforms Subnautica 2 into a synchronized cooperative experience. Built on BepInEx, it provides:

Deterministic Session Synchronization (DSS): Conflict-resolved shared world state across clients
Adaptive Dynamic Scaling (ADS): Auto-adjusts creature spawns and resource respawn based on player count
Shared Inventory System: Merkle tree-based inventory tracking with peer verification
Decentralized P2P Networking: WebRTC-based multiplayer without central servers
Cross-Platform Support: Windows, Linux (Steam Deck), macOS compatibility

The mod operates as a BepInEx plugin that hooks into Subnautica 2's Unity runtime at the IL2CPP level without modifying game files.
