Missable

Whistleblower has 31 collectibles. These are missable trophies. The collectibles must be gained in a single playthrough but they do save as soon as you pick them up. You can create manual save points often along the way so if you do miss one, you can just reload a save prior to your missed collectible and play the game from that point on instead of the beginning.

Notes (recordings) (18) - These are collected by using your camcorder to record something. To record with your camcorder, you just need to hit to bring it out. If you're holding your camcorder, it is recording. Remember, as long as you don't have night vision on, your battery won't drain. You'll know when you're recording a note when you hear Waylon writing on a notepad and you'll see the camcorder icon in the bottom right corner of your screen blinking. Hit to bring up your list of collected notes.

Documents (13) - Documents are your traditional collectible. These are picked up around the environment. These look like flashing blue folders with the word "confidential" written on the front of them. Hit to bring up your list of collected documents
