Excellent. Believably plays like a pro with regard to spray patterns but maybe slightly slower. This is doom for any cheat detect that relies on outliers. Doesn't look aimbotty in the slightestt.
If by "spray pattern" you mean bursts of three shots, sure. But this thing is not playing like a pro in any respect.
Well, it's not public knowledge but it seems that VAC does not care about how it looks. Also while it doesn't look aimbotty, according to modern standards it also sucks at the game. In contrast, many pro players look very aimbotty, but are legit. But ultimately yeah, anticheat will be totally lost.
