Call of Duty Infinite Warfare – Peace to the Fallen Trophy / Achievement Guide – Listened to all of the death letters of the fallen. [Silver / 30G]
You can listen to the Death Letters of the Fallen during the ending credits (after completing all main missions in the story). You do NOT have to collect anything for this. During the credits you can press 8 different buttons on your controller / keyboard. Each button activates a different death letter that will be read to you. The buttons are displayed while the credits play. Don’t take too long or the credits might end before you could activate each letter.
It’s basically a reward for beating all main missions. You do not have to play any of the side missions for this.
