Firstly you have *, **, and *** levels. These tell you which booster pack your playing.
Secondly they are collected the same way you mount a vehicle. You go up to a Generator and by pressing Square you'll put on a Jet Pack.
Create a game and play "Standoff *". On the Chernovan (Red) Side of the valley the generator is litterally next to one of the two bunkers. You'll hear the generator chugging away.
Once you know what it looks like use the opportunity to practice before finding a ranked game. But a word of warning! There are not a lot of people who Host the Jetpack Levels so if you can host a ranked server you might want to try hosting one yourself.
Finally to get the most out of it try and become a member of a clan and invite your friends. Request a friend to host a Jetpack level and maybe you'll be lucky to start playing some on a Ranked Game.
For now create a game with the level you need. Standoff is simple and finding the jetpacks are easy. Remember it has to be a * level to have a booster feature.
