How can you tell if someone is hacking in FEARCombat without punkbuster

Usually someone is definitely Hacking the system when they have 'overkill'.. For example... If you have around 20 kills, and they have around 100; it's pretty obvious they are using a cheat. Punk Buster is no longer available for FEAR Combat because FEAR stopped using Punk Buster. (It cost companies a ton of money to pay for anti-cheat programs) and people usually find a cheat that is undetected by the program and use it in the end anyway. Sometimes you may find a anti cheat program to download and use yourself, However I'm unsure how well it'll work. As long as there are video games out there, you can be sure there will be a cheater too. Just keep in mind that Cheaters never win, and Winners never Cheat!
