Hammond is the latest addition to Overwatch who takes advantage of the game’s physics in a way no other hero does. Which can sometimes lead to players using that for a pretty interesting, and slightly unfair advantage.
Hammond’s Grapple allows him to get basically anywhere on the map by swinging around, and one player has figured out a way to contest the point on Nepal’s Shrine stage for over three minutes using a bit of imagination.
So far it's the only map where this exploit seems to work even though there are other maps, like Hanamura’s Garden stage that present similar opportunities.
The video of the exploit was posted by YouTuber CryBox7, who starts out on the point before shooting their Grapple toward the ceiling and swinging up on top of the center structure’s roof.
From there, they essentially just hang out while simultaneously contesting the point.
Since the enemy team doesn’t have an airborne hero to clear the roof, nobody can really do anything about it.
The opposing side would need someone like Pharah, D.Va, or even a Lucio to get up and knock him down. But since their team's composition doesn't have any of those characters, they can’t reach CryBox7, leaving them team with no chance to take the point while Hammond is nestled up there.
Alternatively, the opposition could just pick another Hammond, do the same thing, and make the round go on forever.
As far as we know, this exploit only works on Nepal’s Shrine stage and even then, the team with the player doing it will be at a 5v6 disadvantage every fight.
But that doesn’t matter if the other team isn’t able to get Hammond down, since he’ll just keep contesting the point forever.
This seems like an exploit Blizzard will probably want to take care of sooner rather then later, seeing how easily it would be to abuse the tactic.
