Although currently in an incomplete state, it represents a major vehicle addition distinct from the player-crafted submarines like the Tadpole or Scout Ray.+The **BigSub** is the current internal name of a large submarine planned to be added in the EA2 update of *Subnautica 2*, albeit potentially in an incomplete state. 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 characteristics.  -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 characteristics. The developers now prefer more general internal names like "BigSub" or "Scorpius".+Information about the BigSub is sparse, though developers have discussed several key aspects of its design and functionality:  -## Key Features+*   **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:- -*   **Acquisition**: The submarine will be found in the world, not crafted. Only one BigSub will exist in a given world or server instance.-*   **Durability & Repair**: Unlike the Cyclops from the original *Subnautica*, the BigSub will not be fully destructible. While it can be put out of commission, it is designed to be recoverable and repairable using the Repair Tool.-*   **Operation**: The vehicle does not require multiple players to operate, making it equally usable in both singleplayer and multiplayer modes. However, additional players can fulfill distinct roles while onboard.-*   **Interior Design**: Though unconfirmed, lead developer Anthony Gallegos has suggested that the submarine could feature a modular interior that utilizes both free-build and pre-built compartments.-  ## Gallery  -### Developmental+### Development  -![An early developmental sketch illustrating the idea of a modular interior.](Big_Sub_modularity_concept.png)+![An early in-development sketch illustrating the idea of a modular interior.](Big_Sub_modularity_concept.png)   ## References   1.

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.
