I didn't make it!
wat is the control scheme for the jetpack, i cant get it to work.
If by control scheme, you mean Jetpack controls, then:
you do /jetpack in console to get one. Jump up and press use (the kind u use to open doors), and that should start the rockets. Press use again to turn it off. While the jetpack is activated, pressing Jump will fire the rockets, making you go heigher
