Tag all criminals visible from the rooftop in Ep. 1: Back to School
Battlefield: Hardline MOTLEY CREW Achievement / Trophy Guide
During Episode 1 you will have to tag enemies from from the rooftop with your scanner. The first one on the street can’t be missed. After you scan him, let him talk to the two guys at the door and wait until he is inside.
Now you can tag 7 more enemies inside the building. He will talk to somehow that isn’t visible from your position. You don’t have to scan him.
After they are done talking, two cars will pull up. Inside are the last 9 enemies you have to tag.
