I knew Halo 4 was an overall successful game to most people.
I never used to be a jetpack person at the beginning of Halo 4, but I choose the jetpack. I have been using it much more recently and it's really useful. I can use it to easily navigate through place, get on top of campers and save time by flying up to places instead of taking a while to walk up the path or stairs which would've been much longer. It also helps get to get to some vehicles and ordnance drops quicker.
