Pathfinder is among the most mobile characters in Apex Legends because of his zip line ultimate and his grappling hook tactical ability. But those abilities provide more than just mobility.
In a match on World's Edge, 09monky spotted an enemy player passing overhead, riding a naturally occurring zip line. Rather than try to shoot the player down as they fly by, 09monky launched their grappling hook up at the zip line.
The grappling hook clicked into place on the enemy player, dragging them down off of the zip line totally unprepared for combat. As soon as the enemy landed on the ground far below, 09monky melted them down with a fully automatic Prowler.
This trick could have use in any number of situations, especially as long as it remains a surprising tactic that puts enemies off-balance.
