In Halo 3 Me and 3 other friends decided to go for the Vidmaster Challenge: Annual. And after trying it for the entire day (about 9 hours) We finally got to the last stretch, and the host got disconnected and we had to restart all over again. So after we were all in the the lobby one of the guys decided to quite, so we wen't in matchmaking to find a fourth, and after about an hour of playing we found a guy who would help us, and at this point it was about 2:00 and we were all tired form doing this vidmaster challenge. So when we had four people doing it we wen't in and were at it for about 2 hours and when we were on the final stretch the way we made the jump( to the pillar of autumn I believe) one of my friends ghost was on top of mine and we jumped together like bad asses, And we barely made the jump but we activated the cuts scene, and after that we got recon. I'll never forgot that moment in Halo 3 mainly because that was when i realized that it was my favorite game ever made, Because I had played the game for about 13 hours straight and was never bored and then as soon as i got recon i felt accomplished. I'll never forgot.
