Okay.

So after watching this replay several times, taking in all potential variables, something in their gameplay was definitely out of the ordinary. And the thing is that I’m still trying to accept the fact that people would take advantage of GunZ in 2020.
I saw very slight float a few minutes into the replays, with out of the ordinary damage inflicted where it shouldn’t have, which at this point in time point me to believe that the user is UCing. Some of his hits just weren't making any sense.

I will keep taking a look at these replays to solidify my opinion, as it indeed has been a while- but as of right now the user should be banned for being unlegit.
