These 2 russian guys on the 24/7 KSA downtown server are glitch abusing and cheating to give them selves like 150 kills with no deaths. Basically there's a building on downtown where you can glitch into the ceiling and these 2 guys keep doing it so one guy kills the other 150 times.
names are [Nuk3]Igor_MVP_OO7 and ashornalen.
Just check into the match logs and realize that going 100 kills with 0 deaths and the other with 100 deaths is them abusing a glitch. Hardline is infested with cheaters and abusers SOMEONE DO SOMETHING PLEASE.
