I have had matches where I managed to get around 25 - 35 kills with say around 3-5 deaths during the game (Rarely without dying), I've also had a nice amount of perfections in my Halo history. But, I'd have to say on Halo 3 when I was playing lonewolves slayer, I managed to get 20 sniper kills, 18 of them being headshots and 5 kills being well places BR shots to the head, I also got a killionaire with the sniper, 6 of them being with the sniper and 4 with the BR. That was back in the day when I had the right mind set (I did love watching MLG back then), I couldn't do this today due to not playing Halo 3 in two years, haha. I'd like to think my BR skills are returning but I don't play enough to really get better.
