Grappleshot

The Grappleshot is a piece of wrist-mounted UNSC equipment.

Overview
The Grappleshot was the product of Project MAGNES, which began in 2549. The Grappleshot fires a grappling hook that can attach to a surface and pull its user towards it, allowing for easier traversal of their environment.

Design
The grappleshot consists of a magneto-impulse projector, a high-tensile nanofiber line, and a self-sharpening Titanium-A fluke contained inside a compact, modular casing. The device interfaces directly with the user's MJOLNIR armor and BIOS systems. The grappleshot has a limited range of eight meters and the fluke cannot always attach itself to ultradense armor plating or energy shielded surfaces. Only augmented personnel can use the grappleshot without extreme risk of injury.

Operational history
In October 2559, Fred-104 uses his grappleshot to strangle an enemy Jiralhanae during Operation: WOLFE, before pulling himself even enough with the Jiralhanae to stab it in the back of the neck.

John-117 made use of a grappleshot with his MJOLNIR Powered Assault Armor [GEN3] Mark VI, during the Battle for Zeta Halo in May 2560.

Halo Infinite
The Grappleshot is a piece of usable equipment in Halo Infinite, which the player can use to move rapidly towards a location or enemy. It can also be used to retrieve distant items, such as fusion coils or a gravity hammer. The grappleshot can also be used to stagger Kig-Yar Freebooters and Raiders, knocking their hand-held shields aside and briefly rendering them exposed. The grappleshot itself also deals minor damage, enabling it to finish off severely damaged enemies. After use, the grappleshot has a short cooldown time before it can be used again. If the grappleshot fails to connect to a surface, is used to stagger a Kig-Yar, or is used to finish off a wounded enemy, the cooldown will not be triggered. Like other pieces of equipment in the campaign, the grappleshot can be upgraded by collecting and spending Spartan cores.

The grappleshot is available in multiplayer as well, but with only 3 to 5 uses before running out of charges.

Upgrades
In the campaign, the Grappleshot can be upgraded using Spartan cores.


 * Voltaic (1 Core): Grappleshot stuns grappled enemies for several seconds. Stunned enemies will either be electrocuted or will assume defensive postures and freeze in place.


 * Quickshot (2 Cores): Reduces Grappleshot cooldown by 40%.


 * First Strike (3 Cores): Delivers a powerful shockwave blast when holding the melee button while grappling.


 * Reachfall (3 Cores): Increases the damage and radius of the shockwave blast. Enemies within it will be stunned.

Trivia

 * During a cutscene in the mission Excavation Site, John-117 uses his grappleshot to swing a loose container at Bassus, an ability not available during actual gameplay.

Production notes
While the Grappleshot's first in-game appearance occurred in Halo Infinite, the idea of a grappling hook has been around for many years, with Bungie or 343 Industries trying the mechanic on several prior Halo titles, ultimately shelving it due to the mechanic not working well.
