subnautica-ii-coop-deep-synergy-mod

What problem does it solve? Subnautica 2 ships without native multiplayer, so players who want shared survival sessions need a mod that synchronizes game state, inventory, base-building, and creature AI across clients without central servers. ## Core Features & Use Cases - Deterministic Session Synchronization: Peer-to-peer WebRTC connectivity with Merkle tree inventory verification keeps game state consistent across all players. - Configurable Session Profiles: A synergy_profile.json file controls difficulty scaling, resource multipliers, oxygen consumption, and network tolerances. - AI Narrative Integration: Optional OpenAI and Claude API hooks generate contextual journal entries and creature lore reports during play. - Use Case: A group of four friends installs BepInEx, drops the Deep Synergy plugin into the plugins folder, shares a session code from the console, and plays a synchronized co-op campaign with adaptive difficulty. ## Quick Start Install BepInEx 6.0.x IL2CPP into the Subnautica 2 directory, place the Deep Synergy plugin files under BepInEx/plugins/DeepSynergy, then launch the game and run /start_server in the BepInEx console to get a session code for friends to join.
