Like every game in the series before it, Gears of War 4 collectibles are littered throughout the game's campaign. Not only do these give you an excuse to explore every nook and cranny of each blood-soaked stage, but each provides a nugget of story-info that fleshes out what's happened in the decades following the events of the Xbox 360 trilogy. (There's also a few Achievements in it, too.)

Below each are links to where to find all 50 hidden collectibles, describing at what point in each chapter you'll come across them - as specific but as spoiler-free as possible - as well as imagery that'll narrow down their location.
