Are you looking for individual or team record?https://www.youtube.com/watch?v=HNWVtwO9kgQ
I know there are some pretty insanely high army of one style single player kills. I got 68 on my first try in archives, and that was against a constantly quitting enemy team.
Klams has an 88 kill game. I think there's a picture somewhere... It was for the 50/50 challenge.
Legend has it that Cyber/SD posted a 103 kill game.
