I have manage to get a perfection, but I died once in the game so here is a video on Bungie.net for you guys to download and watch (video not rendered) : Bungie.net : Halo Reach : File Details I guess the reason why it happened was because of the host migration happened exactly when I died. I have 2 killing sprees and I still manage to get a perfection and thats not even possible, but heres the proof that I got it (Gamertag "Cortez XD"): Bungie.net : Reach : Game Details This is the most awesome perfection ever!
