It was normal for the first round, then changed to Oldschool Hardcore Search & Destroy in the second round.
I thought you had to change your clan in the lobby before the match started for this to be possible, not after the first round..
its up to yourself, if you change your tag before the match starts then you will have oldschool in round 1 - till the end of the match.
If you goto options in the first round you will have oldschool the second round till the end of the match.
lol i do this all the time it so much funner this way, and no u can do this in anyround actually just know the round comes after it will start, but best to do it in the beginning
