I was playing a COD4 deathmatch a while ago. Since, I am new to online gaming, I am not sure if player are hackers or not. I faced a guy who does not seem to be taking any damage. I emptied 4 rounds of shotgun into his face. Yet, there were no hits on his body. He doesn't even jump or dodge bullets. My friend emptied 2 mags of M4 into him and that finally killed him. Is this guy using some 'superhealth' cheat or something? And no, this guy was not using the juggernaut perk.
