Yup, was back in the days when I played Star Wars Republic Commando, I had like four matches where I got over 85 kills on the best thing is I was playing it with a friend of mine who only had like 17 kills when I scored kill nr. 76
By the end of that match I had 89 kills and he had 26, still the highest kill score I've ever gotten in that game is 128 kills
Nowadays, I don't really play FPS-multiplayer so much anymore
