I could have sworn I was watching an Anime with that kind of thing...
"Attack on Titan's"?
Made absolutely no since, but it was okay XD

Just be careful not to grapple onto an enemy you're killing. Apparently, it resets the grapple point to your spawn if it's on an enemy when they're killed, and if that's far from where you are... Well, you'll pretty much end up a pixelated smear on the terrain

yeah i had one guy get me into it too the anime is astounding with its style
