Hi, I just spent two hours playing ODST Firefight to get the achievement Vidmaster: Endure. Well, we completed the fourth set and during the bonus round, we get an unknown error. Nobody lagged out or anything, and we don't get the achievement. It is complete B.S. You can even check my recent games, my gamertag is Teh Wizzard. We should have gotten the achievement after the fourth set regardless if there was a bonus round because even if every player dies during the bonus round, you still move on.
Why didn't we get the achievement.
