This past Memorial day weekend myself and 3 friends were up to some achievement hunting. We wanted to get all the firefight achievements in ODST. While we were playing there would be an occasional bad lag spike, but the biggest problem is, like clockwork, everytime we made it to end of the first 3 rounds or after the bonus round, the connection would just drop. It would kick one player or none actually, and just say that a player left. We've been playing other games with no problem, like Left 4 dead and CoD. 3 of us are in Texas and another in Colorado. We used the Crater map. Does anyone know what the problem could be? Are the ODST Bungie servers going bad?
