I would like to see the Grapple Glove or Grapple Plunger released with a new option where it can only connect to grapple points that are manually placed in our maps and are in distance with the player, so you could either pick up the item and use it where these grapple points are available or a simple prompt shows on screen where you can auto use the item but it does not count as taking up a weapon slot so maybe like the environment trap where you carry it but it is stored in an area not where weapons are kept.
This is how it worked in Far Cry 5
The grapple in Far Cry 5 can only be used when a grapple point is within distance of the player, this is when a prompt will show on screen enabling the player to connect to the grapple point if they want to.
We can alter the length of rope so if the player could fall to their death from the height you could make the rope longer so they can climb / slide down the rope to a safer height.
The good thing with this is you can make areas where the player can not reach until they get close where the Grapple Glove and Grapple Plunger in Fortnite connect to almost anything, some issues here are that players can get out of the map or to areas you might not want them to be in or it adds more work for the creator boxing them in using more items which is a further drain on memory.
I think it would be a great idea to modify either the plunger or the grapple glove in giving us a new one that would only work when it comes into range of a grapple point which we would place manually in our maps.
Allowing us to set the distance on each grapple point so the plunger / glove could then shoot out the correct length of rope for each point it connects to.
Also have either no cool down and no number of uses or add in an option to alter the cooldown to no cooldown and alter the number of how many times we get to use this up to infinite / allow the player to hang there and swing as long as they want without the device over-heating and allow easy connection from one grapple point to another.
I think a similar thing where the grapple options shows up on screen as a popup when in range of the player.
This would be really useful having an item to use like this especially for Obby / Parkour maps / Escape type maps and maybe even Rogue / Exploration type maps where you have to get to new areas.
