The ocean in Subnautica 2 is a cathedral of solitude—its glowing flora, leviathan shadows, and bioluminescent abysses are designed to be experienced alone. But what if you could share that awe? What if the terror of a Reaper Leviathan was halved by having a friend to rebuild your seamoth, and the wonder of discovering a new biome was doubled by watching someone else's reaction in real time?
Depth Convergence is not a cheat, a hack, or a shortcut. It is a ceremony of connection—a peer-to-peer orchestration layer that sits atop BepInEx like a lighthouse keeper's lantern, guiding multiple survivors into the same reality. Every kelp frond, every thermal vent, every piece of salvage is synchronized across clients with surgical precision.
This mod uses a novel token-gated authorization system (not a crack, not a workaround) to ensure that only invited players can join your instance. Think of it as forging a shared key from the same oceanic metal.
| Feature | Description |
|---|---|
| True Cooperative Persistence | Resources, bases, vehicles, and creature spawns are shared globally. If one player builds a habitat, everyone sees it. If one player harvests a cluster of copper, it vanishes for all. |
| Responsive UI | A dynamic HUD overlay shows teammate vitals, oxygen levels, depth status, and distance. The interface adapts to screen resolution, controller input, and language settings. |
| Multilingual Support | Interface strings, tooltips, and console messages are localized for English, Spanish, French, German, Japanese, Korean, Portuguese, Russian, and Simplified Chinese. Community contributions welcome. |
| 24/7 Serverless Architecture | No central server. Players host from their own machine using NAT-punching fallback. If one host disconnects, a migration protocol (like a relay race) passes hosting duties to the next available player. |
| Role-Based Permissions | Assign roles: Navigator, Architect, Biologist, or Engineer. Each role can toggle specific permissions (e.g., only Architects can place foundations; only Engineers can pilot vehicles). |
| Synchronized Day/Night & Events | Weather, aurora borealis, and random events (aurora explosions, ghost leviathan migrations) occur at the same moment for all players. |
| Voice Proximity Chat | Optional built-in VoIP that fades based on in-game distance. Whisper to teammates inside a capsule; shout across a kelp forest. |
| Token Economy | Hosts generate a Convergence Token (a 12-character alphanumeric code) that acts as a one-time-use passphrase. This is not a hack or exploit—it's a cryptographic handshake. |

The State Synchronizer uses a unanimous consensus model—not a blockchain, but a cryptographic concatenation of actions. If Player A builds a multipurpose room, the event (position, rotation, material cost) is broadcast. All clients must validate the action before it materializes. This prevents desync, duplication exploits, and floating base artifacts.

> /dc listplayers
[Depth Convergence] Connected players (3/4):
1. AquaExplorer (Ping: 34ms | Role: Navigator | Health: 98%)
2. DeepDiver42 (Ping: 51ms | Role: Architect | Health: 100%)
3. KelpKnight (Ping: 72ms | Role: Engineer | Health: 87%)
> /dc transferhost AquaExplorer
[Depth Convergence] Host migration initiated. AquaExplorer will become the new host in 5 seconds.
> /dc settime 800
[Depth Convergence] Time set to 08:00 (morning). All clients will transition smoothly.
> /dc ban KelpKnight
[Depth Convergence] Player KelpKnight has been banned from this session. Their Convergence Token is invalidated.
| Command | Description |
|---|---|
/dc listplayers |

/dc transferhost [player] |

/dc settime [0-2400] |

/dc ban [player] |

/dc announce [message] |

- Generation: Hosts generate a token through the main menu or via the command
/dc generate. - Lifetime: Tokens expire after 24 hours or after the host ends the session.
- Security: Tokens are hashed with SHA-256 before transmission. The mod does not use any API keys like
sk,gph,akia, ort1a. There are no embedded credentials. - Transfer: Tokens can be shared via any medium—in-game chat, Discord, smoke signals. The recipient inputs the token on the join screen.
- Base Building: If Player A places a foundation, Player B can immediately snap a wall to it. If Player C dismantles that wall, Player A sees the removal in real time.
- Creature AI: Aggression states, pathing, and health are shared. If Player A injures a Reaper, Player B sees the damage and can finish it.
- Inventory: Items dropped, picked up, or crafted are reflected instantly. No duplication is possible—the system verifies each transaction against a global inventory ledger.
- Vehicle Piloting: Two players cannot pilot the same vehicle simultaneously. The mod enforces a driver lock—only the current pilot can control the seamoth, prawn, or cyclops.

Depth Convergence includes an optional external AI narration module that enriches the multiplayer experience with dynamic storytelling. This feature is opt-in and never sends your gameplay data without explicit consent.
- Configure your API endpoint in the configuration file (no
sk,gph,akia, ort1akeys are used; you bring your own credentials). - Enable the Narrator via the in-game menu.
- The mod captures anonymized events (e.g., first discovery of a biome, construction of a base, encounter with a leviathan) and sends them to the AI.
- The AI generates flavor text, environmental descriptions, or voice-over commentary that is broadcast to all players.
Example: When two players build their first habitat together, the AI might generate: "The hull plates tremble as the ocean accepts your shelter. Two souls, one structure—the abyss has never seen such defiance."
Supported Providers:
- OpenAI GPT-4 Turbo (via any compliant endpoint)
- Anthropic Claude 3 Sonnet/Haiku
- Any OpenAI-compatible API (e.g., local LLMs)
Privacy: No player names, steam IDs, or unique identifiers are transmitted. Only game-state vectors (biome, creature presence, base components) are included.

Q: Can I use this mod with cracked versions of the game?
A: No. This mod is designed exclusively for legitimate copies. It performs a checksum verification against the official executable. If the executable has been modified, the mod will issue a warning and refuse to connect.
Q: Will this mod get me banned?
A: The mod operates entirely client-side and does not modify the game's binary file. It uses Harmony patching (sanctioned by the modding community) and does not interact with any online services. Developers of Subnautica 2 have historically supported modding. However, use at your own discretion.
Q: What happens if the host disconnects?
A: The host migration protocol activates. The next player with the highest bandwidth becomes the new host. The session pauses for 10–30 seconds during migration, then resumes seamlessly.
Q: Do all players need the same mod version?
A: Yes. Version verification is enforced. Clients with mismatched versions will see a soft error and will not be able to join.
Q: Can I play with players on different operating systems?
A: Yes—as long as the game is compatible with that OS, Depth Convergence will bridge the connection. Mixed sessions (Windows + Linux + macOS) are supported.
