What makes the 41 "war journals" hidden throughout Gears of War 2 so absolutely crucial? Each one tells a unique piece of the game's story – newspaper clippings, medical records, artifact analyses, soldiers' letters and more. Beating the game will provide you with the broad strokes, of course, but the overall puzzle is incomplete without the war journals."
