ok if you want you breeze through BB missions with your team and get easy xp you want this guide. What you do is if your on a team make someone you trust the leader and quit the team. Go in your BB mish and put on invisibility or stealth then run through the whole mish without getting seen or attacking anyone (you cant open crates either) then exit the mission, join you team and do the mission and it will still be set as a 1 person mish.You can breeze through and get the team bonus to.
