Lost & Found Weapon Quests are normally prompted by a found document or some form of paper trail that you’ll need to follow, with clues highlighted in red text in relevant Journal entries. For the most part, you’ll have to complete several steps, like a scavenger hunt, and you’ll be rewarded with a fancy weapon at the end.
