SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Deep Synergy co-op mod solves the problem of playing Subnautica 2 multiplayer with reliable synchronization, where world state, inventory, and game progression can otherwise drift or desync between players.

Core Features & Use Cases

  • Deterministic Session Synchronization (DSS): keeps shared world state consistent across clients.
  • Adaptive Dynamic Scaling (ADS): adjusts spawns and resource respawn based on how many players are in the session.
  • Shared Inventory System: synchronizes inventories with verification to reduce item inconsistencies.
  • Decentralized P2P Networking (WebRTC): enables multiplayer without central servers.
  • Use case: start a cooperative Ocean Explorers session with multiple friends, share blueprints, and keep creatures/resources consistent while exploring together on Windows, Linux (Steam Deck), or macOS.

Quick Start

Install BepInEx for Subnautica 2 IL2CPP, place the DeepSynergy mod files into BepInEx/plugins/DeepSynergyMod/, launch the game, then run /start_server to create a session code for your friends to join.
