The Sea Truck is a vehicle that specializes in its customizability. Inside the cabin, there is an area used to pilot the Sea Truck and a lever used to detach all modules. There are several modules that can be attached to the Sea Truck to form a long chain. Each module serves a different function. An unmodified Sea Truck has a crush depth of 275m, but may be increased through depth modules.


The Sea Truck can be used as a mobile seabase, or as a quick submersible. It allows the player to explore deeper biomes.

It requires Energy from two Power Cells to function. The vehicle has its own Oxygen supply, and will replenish the player's oxygen unless the power has been depleted. The Sea Truck Cabin can be docked in the Moonpool to recharge. When docking, all modules automatically detach to allow the cabin to enter the Moonpool.

The Sea Truck Cabin has a health meter, and reaching zero will cause the cabin to explode, and leave any connected modules unaffected. The Sea Truck Cabin can take damage from being below its max crush depth, being attacked by hostile fauna, or by colliding with the terrain. Sea Truck modules have individual health meters, and are invulnerable to damage while they are connected to the cabin. Damage can be repaired with the Repair Tool.

The vehicle can be entered from a hatch located on top of the Sea Truck Cabin, or through an airlock at the rear if any modules are attached.

When going backwards, a camera facing behind the last module will be displayed on the right side of the Sea Truck's screen, allowing players to navigate behind them.


Sea Truck modules can be attached to the back of the main compartment and can be linked to each other. The modules can be individually picked up and moved externally, but it is slow to do so. The player is unable to build anything in the modules, including the cabin, using the Habitat Builder.[1]

Modules decrease the overall speed of the cabin when attached. This effect increases as the number of additional modules increases.
