It isn't my video, nor do I know what the wallhack thing is about.
I recently reported a guy who got banned for multihack, but the way I found him was he was doing this same thing (spamming ucavs with no cooldown).
I UCAV regularly and have never heard of a way to glitch it to do this. Have any of the admins here confirmed it is possible to do this with a glitch?
I know for a fact it is possible to do this with a multihack as that guy who had 59 HS / 62 kills with LMG was doing it, but I would be genuinely curious if anyone here can replicate it without a hack.
Has anyone done this? I'm not asking you to show me how or anything, I would just like to confirm if it is possible or not without modifying the game files so I won't report people who I see doing it.
