Quickscope aimboting?

seen some stuff ingame of some sick quick scope aimbots, and sure some people are REALLY good at quick scopes and dont use hacks, but i mean i seen them in every game the past few days.. Any idea how they're doing it, i know i seen a few of the QS scripts recently, but these guys had perfect quickscope aim through a window across map on me, any ideas?

You can just use an aimbot and a quick scope script to do that, I know quite a few people who do that

How would you set it up? script for middle mouse, and set aimbot key to middle mouse i assume?

I don't know hey sorry there aren't many undetected aimbots around for mw2 so theres your real problem right there
