Can't think of the specs right now but I'm thinking just something along the likes of the way the scanner, or cloak works? Like it takes a little while to recharge.. Except this tempory jump boost or jetpack shoots you up quickly but it has drawbacks. Makes you scanable, you run into stuff you either die or get damaged, has a weight factor, so commandos can't use it as well But it doesn't have to do with the myofibs, so min doesn't get a bonus. And maybe it's a consumeable like the nanohive, you get maybe one shot basic two shots advanced with higher jump, obviously you can guess the variants. Maybe it doesn't need any more visual mods either, it can just be the opposite of the X you press while you fall, and also another drawback, if you don't X before you fall you die, so you gotta be careful using it. Or maybe just make a sustainable flight type or equipment. But that's a whole nother topic. Lemme know what you think
