Just playing Call of Duty and noticed the death machine spins and I always wondered why.

Theoretically you could make a gatling style weapon without spinning barrels, but you’d require a system for loading bullets into each barrel, and firing each barrel. It’d significantly increase the weight to have a separate system for every barrel for no benefit, besides maybe being able to skip a barrel that wasn’t working.
