There isn't a "Jetpack" usage...the game has them graphically but they're implemented to make it more believable why you jump from the Ship (Like the plane in PUBG) to guide yourself to the area you'd like, or if you jump off a large cliff - To anyone else, it looks like they fire as you super hero land on the floor. It's MUCH more closely matched to Black Ops's BR - Just with a futuristic feel, all guns shoot bullets
