Prawn Suit Grappling Arm (Subnautica)

The Prawn Suit Grappling Arm is an upgrade module for the Prawn Suit which replaces an arm with a grappling hook. This hook can be fired and will latch onto surfaces to pull the Prawn Suit towards it.

Description

The player can latch onto surfaces as if using a traditional grappling hook by holding Left Mouse Button (LMB) or Right Mouse Button (RMB), depending on which arm the Grappling Arm is equipped on. The hook fires, latches onto a solid object within range, and reels the player in with the Prawn Suit.

Because the Prawn Suit's jump jets have limited range, the Grappling Arm is an effective way to extend the suit's reach or maneuver out of challenging environments. It is especially useful for keeping the Suit in place while drilling for Large Resource Deposits attached to cave walls.

Interaction with Fauna

The Grappling Arm has the capability to latch onto and reel in certain Fauna. With smaller creatures, this allows the player to capture them from long distances more easily. Latching onto larger creatures, however, will reel the Prawn Suit towards them, as they have significantly more mass than the Suit itself. Combined with an arm that can deal damage, this allows the player to scare off larger creatures or even kill them. However, this also allows the grappled fauna to attack the player, resulting in additional damage dealt to the Prawn Suit.

Mobility Techniques

The grappling hook is a very useful tool for increasing the Prawn Suit's mobility. It can be fired at the terrain (especially at walls/ceilings) in front of the Prawn Suit to greatly increase its horizontal momentum by swinging forwards, even momentarily exceeding Seamoth speeds.

The hook must be released before the grappling hook pulls you all the way to your target; otherwise, the suit's momentum will slow down as you approach the target.
The Prawn Suit Jump Jet Upgrade pairs well with the grappling hook technique, allowing you to alternate between jets and swinging forwards to rapidly cross large distances without landing.
An additional grappling hook allows for faster acceleration, reducing the distance needed to reach full speed.
