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. In Creative, the player starts with a Propulsion Cannon in their inventory.

Usage
While aimed at an object, the Propulsion Cannon can be used to suspend the object and pull it closer to the player (see "Controls" below). Suspended objects can then be launched or dropped softly. It is also possible to add suspended objects directly to the player's inventory or to load objects directly from the player's inventory into the cannon's beam.

The Propulsion Cannon is able to suspend most small-to-medium-sized objects within a range of 19 meters from the player, including small Fauna, Flora, Harvesting Nodes, and various debris found in the Aurora and in wrecks. This makes the Propulsion Cannon useful for navigating wreckage, obtaining hard-to-reach items, and catching fish. The Propulsion Cannon is even capable of grabbing Bleeders latched to the player's arm and blasting them away.

Because the Propulsion Cannon is able to load and launch items directly from the player's inventory, it can also be used as a weapon. It is capable of dealing damage when loaded with Gas Pods or Crashfish.

Energy
The Propulsion Cannon uses energy from a Battery, which can be replaced (see "Controls" above). While picking up objects does not use any energy, holding objects with the Propulsion Cannon uses 1 unit of energy every 1.43 seconds (41.96 energy per minute, 143 seconds for a full Battery or 715 seconds for a full Ion Battery). Launching objects uses 4 units of energy.

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

Trivia

 * The Propulsion Cannon has many similarities to the gravity gun from the Half-Life series. The developers have admitted to using it as a design inspiration.
 * The largest object that can be grabbed is the Seamoth, although it is difficult to move.
 * The Propulsion Cannon's first model, used in early access was reused for the Stasis Rifle.
 * When you acquire the Propulsion Cannon blueprints, It shows the image for the Prawn Suit Propulsion Cannon instead of that of the Propulsion Cannon.
 * The Propulsion Cannon is referred to as the "gravcannon" in the sound files.
 * An unused reload sound effect exists within the game's files.

Bugs

 * When the Propulsion Cannon is used on an object directly beneath the player's feet, the object will be pulled upwards without colliding with the player, but the player will collide with the object. Thus, "flying" is possible.
 * It is possible to pickup an Waterproof Locker or a Carry-all even if they aren't empty by using a Propulsion Cannon to load it into your inventory. This can be used for practically infinite storage.
 * If you pick something up with your propulsion cannon in a flooded base it may increase the speed of your Seaglide.
