Prawn Suit Grappling Arm (Subnautica)

The Prawn Suit Grappling Arm is an upgrade module for the Prawn Suit that adds an arm that can be fired and will latch onto surfaces to pull the Prawn Suit towards it.

The player can latch onto surfaces as if it were a traditional grappling hook by holding or  (depending on which arm the Grappling Arm is equipped on) to fire the hook, have it latch onto a solid object within range, and having the player reel in with the Prawn Suit.

Because the Prawn Suit's jump jets have limited range, the Grappling Arm is a good way to extend the suit's reach. It's especially useful for keeping the Suit in place while drilling for Large Resource Deposits attached to cave walls.

The Prawn Suit Grappling Arm has the capability to latch onto and reel in certain fauna, though due to distance being favorable when encountering most species in the game the usefulness of such an ability is limited.

​Trivia

 * The grappling hook can be shot at the ground in front of the Prawn Suit to greatly increase its horizontal momentum, even momentarily exceeding speeds capable with the Seamoth. The hook must be released before the suit reaches it otherwise the suit's momentum will be disrupted.
