I was on invasion, I walked into the video store. Saw the guy i was behind him, was in the process pushing the thumb stick to knife his ass. And the dude whipped around and capped my ass......i was like wtf how is that even possible
Well there are several ways he did that.
First though were you using Ninja pro (silent footsteps)? If not, he could have heard you, especially if he had sitrep pro (louder enemy footsteps) on.
Or he just flat out heard you and spun around firing.
I am the absolute MASTER at drop-shotting. Its my way of getting back at halo hopping assfuckers. If I run by someone, I'll duck to the ground and spin around firing. I did that to the same guy in a match 5 times and he never caught on. After the game he told me how good I was at it.
