The two default grappling hooks are
Pulls you toward the anchor point, also pulls you in the direction you are looking (based off of titanfall 2)
Lets you swing from high places, or catch yourself mid fall and hang there
The default keys are A+W+D for pull, A+S+D for rope. Can be changed in the config (see video)
The grapple will end if you look far enough away from the anchor point
You’ll be saved from fall damage for a short time after grappling
As you play and use the grappling hook, you gain experience. That experience can then be used to upgrade your grapple. Or you could scrap the default ones and build your own.
