A Grappling Hook is a Burst Movement Option and Context-Sensitive Movement Option made unique by the player character’s use of a lasso-like device or Projectile to pull themselves to a new location, often with momentum. Grappling hooks may also be used as an Attack, to varying effects. Because of the large amount of distance able to be covered with Grappling Hooks in most games, the ability to use the Grappling Hook is often linked to progression as a Gating Mechanism.
There are two common functions of a Grappling Hook. The first simply is to simply pull the player character to the location of contact, typically in a straight line. The second is to create a tether between the player character and the location of contact that allows them to swing in an arc. A given Grappling Hook may have one or both of these functions. Additionally, Grappling Hooks often feature specific limitations on what locations of contact are functional, and behavior may vary when contact is made to a disallowed surface.
