Wannabe Fortune Hunter is a Bronze trophy for finding more than half of the collectibles. You need 121 of the 240 that count, in any mix of categories.
Pick up collectibles as you explore and clear camps. Most players reach half naturally by the late game.
Use Survival Vision in towns and at NERO sites. Eagle-Eyed and Eye For Detail make scanning easier.
