Propulsion Cannon (Subnautica)

The Propulsion Cannon is a tool crafted with the Fabricator. It can be modified to the Repulsion Cannon with the Modification Station. The Propulsion Cannon takes up four slots in the player's Inventory.

Usage
The main function of the Propulsion Cannon is to attract and launch objects with its beam, including small Fauna or Flora and Harvesting Nodes within a range of 19 meters or less. It is also used to move away debris blocking the player's path in the Aurora and in wrecks.

Objects can be suspended via the Propulsion Cannon by aiming at the object and pressing. The player can also load an item from their inventory into the Propulsion Cannon by pressing. Once an object is loaded, the player can launch the object by pressing again. Pressing with an item loaded releases the object without launching it.

Attracted objects can be picked up by the player with. This makes the Propulsion Cannon useful to catch fish and pick up hard-to-reach items.

If a Bleeder latches onto the player's arm, the player can use the Propulsion Cannon to grab the Bleeder. It can then be blasted off.

Energy
The Propulsion Cannon uses energy from a Battery or Ion Battery, which can be replaced with.

Launching objects uses 4 units of energy.

The Propulsion Cannon can be recharged with the Swim Charge Fins.
