Above: All emblems from chapter 1
Emblem 1: After an RPG blocks your intended route through the street, you’ll detour through a building. Ascend some steps and look to your left once you reach the room with the pigs.
Emblem 2: Soon after the fight with the first mutated J’avo, you’ll engage in a firefight with a group of hostiles, during which more enemies will emerge from a garage to your right. In the next room you’ll find a lone crate right in front of you. Smash it reveal an emblem.
Emblem 3: As soon as you get back onto the rooftops, you’ll be shown the “Ace of Spades” via a short cutscene. After the scene, turn around and look for a building draped in green in the distance. There’s an emblem atop its highest protrusion.
Emblem 4: While you’re moving between floors rescuing hostages, you can find the chapter’s final emblem on the 6th floor behind some hanging meat. Make sure to get it before taking the elevator to the first floor.
