I cant remember to well from my first playthrough of how many I missed or not.
But do any of you guys know how many of the missions that have optional objectives in them? included DLC

Problem I had, I joined a friends game to do the hyperion slaughter, he was in 4th and 5th round, but it didnt count for me.
And as I did it, they didnt pop up for me on the challange rank, they got skipped.

so beware to join others about this
