Cabela's Big Game Hunter 2012

Detective mode is activated by pressing and allows you to see animals, signs, noisy environments, blinds and cover. You will be using this regularly and, as such, this trophy will almost surely come naturally during the normal course of the game. If you somehow haven’t unlocked this by the time you finish all the other story mode trophies, just load up any mission, activate detective mode and leave it on until the trophy unlocks.
