J is for Jump Pack!
Jump Packs are favorite of mine. I have loved them since the first days of seeing them used on Lost in Space! On TV. So what about them?
Well if you want to use them, what are they? Have they developed enough into a military tool. It it still a full rig and platform, or are you full rocketeer/iron man mode. Militarized and a staple of the civilian market.
My preference is the latter. I have always seen full peer armored soldiers in jump packs zooming over tortured landscapes to capture the objective ahead of the ground pounders.
So this fits a space opera game. Now simply decide on size and weight of the system. Does it take a fully armored and etched out suit to use one? Can it just be strapped to you back or your boots? How is it controlled? How would an adventurer use it, and of course fire a weapon from it?
The jet pack could add some nice technology quests, escort missions or full out combat missions with jet packs as a main player in the adventure. So use them. You characters will love soaring through the air.
