Far Cry 4 Edit
The Grapple is a form of equipment that appears in Far Cry 4. Ajay Ghale is able to use the grapple to reach across gaps and unto higher levels. Though it can only be used at designated areas, which are marked by a series of orange ropes, bolted to a cliff, these are very common and scattered across Kyrat, with possibly thousands on the map. Do be warned that you cannot use any sort of weapons while climbing with it, but you can still take damage and you can still be spotted, so be sure to watch for enemies before you begin climbing up.
Far Cry 5 Edit
The Grapple from Far Cry 4 returns in Far Cry 5. It functions the same way, to equip and unlock the Grapple, you need to buy it using perk points from the perks menu. It costs one perk point.
