Audio Logs
Audio Logs are collectable items in Red Faction: Armageddon that provide lore surrounding both the current story and the past events that lead up to this point. In-game, these logs are easily identifiable by their blue beam of light that expands as it gets closer to the audio object, highlighted by the spherical visual effect at the top. The player must use the "use" key when close to one to listen to the device in game.
Once listened to, these audio logs are unlocked as audio snippets in the games "Extras" menu from the main menu, allowing you to listen to them again at your leisure.
Collecting these Audio logs will complete the Chronicler achievement.
