I do not recommend you guys to use this script if you don't want to get ow banned.
I got overwatch banned yesterday using this on a rank two account. I played 1 match, next day I see ow ban (no, I did not injected any cheats, just the script to test it).
Also, you can't bhop or move properly, which is, in my opinion, a waste of time and it made my gameplay worse.
Good news is that you get better accuracy and its easier to kill enemies, but, in an overwatch, it looks like aimbot if you have decent movement and mouse placement.
