By far, the Ninja challenge is one of the hardest, if not THE hardest challenge in all of Black Ops 3. You have to get 5 clutch medals by defusing the bomb when you are the last player alive and enemies are alive in Search and Destroy. It sounds easy enough, but in actual practice, it's frustrating beyond belief. There ARE tactics and strategies as well as a few tips and tricks that can help you along the way, but it also boils down to having a lot of luck on your side. My goal is that you can combine at least a few of these tactics into your Search and Destroy game plan and be successful at getting these 5 clutch medals.
