Above: All emblems from chapter 2
Emblem 1: While you are covering Finn, run to the opposite end of the area and look for a storage container with a makeshift window. Through the bars you’ll spot an emblem.
Emblem 2: Once you reach the bridge, Piers and Chris will split up. As Piers, head to the perch from which you can view the whole bridge. Look at the upper right part of the bridge to spot an emblem. (You may be able to get this emblem as Chris once you get to the upper level of the bridge, after the tank is destroyed.)
Emblem 3: As soon as you enter the mansion, stick to the perimeter of the room (either side) and loop around to the back of the stairs. You’ll find an emblem in the back hallway.
Emblem 4: Once you meet up with Ada, she’ll lead the way through a door. Instead of immediately following her, check the small room nearby for an emblem.
