I've just been killed in Berezino by a guy with a .22, he shot me several times at many different places, first at the hospital roof, then in one of the hospital rooms and finally at a house that i ran to. This obviously wasn't a case of aimbot, however I didn't see him once, and he suspiciously knew exactly where I went. So this was likely a case of wallhacks instead of aimbot (progress i guess), but still very annoying and unfair for obvious reasons.
This has happened around ~10 mins before this ticket was created.
