The submarine previously used the internal name **Trident** until it was changed due to potential trademark concerns and because the name implied too much about the vehicle's specific capabilities or lore.  -*   **Acquisition**: The submarine will be found in the world, not crafted. Only one BigSub will exist in the game world.-*   **Durability**: Unlike the Cyclops from the original *Subnautica*, the BigSub will not be fully destructible. While it can be put out of commission, it will remain recoverable and repairable using the Repair Tool.-*   **Operation**: The vehicle is designed to be equally usable in both single-player and multiplayer modes. Multiple players are not required to operate it, but additional players in co-op can fulfill distinct "jobs" or roles within the submarine.-*   **Interior Design**: Lead developer Anthony Gallegos has suggested that the submarine could feature a modular interior, potentially combining free-build spaces with pre-built compartments that can be swapped out, similar to base management in games like *XCOM*.+Information about the BigSub is sparse, but developers have discussed several key aspects of its design and functionality:  +*   **Acquisition**: The submarine will be found in the world, not crafted.

No idea what we'll call it | because for all i know trident is owned by some trademark" - October 9, 2025.-5. Imgchest - "We've been trying to move away from internal names for stuff like 'Trident' as it implies too much about the thing (biome, vehicle etc), so we have more general things like Big Sub or Scorpius" - July 15, 2026.-6. Discord message - "you will acquire the big sub" - March 28, 2026.-7. Imgchest - "i can answer that, i think. Yes. I want it so the big sub is recoverable, rather than destroyed. So think of it as the server would have A big sub" - April 22, 2025.-8. Discord message - "For the bigsub, we will likely have 'jobs' for each of the 4 coop players, however you will not need 4 players to use it. We are a single player game with optional coop. We will unlikely ever introduce anything that is only single player or coop player focused" - July 30, 2026.-9. Discord message - "i still think some degree of modularity is potentially cool. Like if we had a free build space on the big sub, but also rooms you could wholesale swap out like an XCOM base" - June 2, 2026.+![An early in-development sketch illustrating the idea of a modular interior.](Big Sub modularity concept.png)
