hack

Turns out Sombra isn't the only one hacking In Overwatch. Aim-botting, sometimes referred to as 'hacking' by frustrated players is something that any skilled player has been accused of. Akin to the aim assist of consoles, it is difficult to detect and often based on overlay rather than any sort of code insertion.
But one thing's for sure. It's a plague. Hop onto any older PC shooter and it will be rampant.
Apparently that plague is a bigger problem in Overwatch than we'd thought.
