Nomad's gadget is the Airjab Launcher, which shoots Airjabs. Airjab, which are small devices that can stick to any surface and when a defender enters its proximity, it will launch them on their backs, as well as attackers if they are close enough. Nomad can shoot three Airjabs. (Can only be detonated by proximity of defenders.)
Kaid's gadget is the "Rtila" Electroclaw, which has a similar function as Bandit's batteries. The difference is, the Electroclaw can be thrown and has an area of effect radius, so it does not need to be directly on a reinforced wall or reinforced hatch to electrify it. One Electroclaw can electrify multiply things, and Kaid has two Electroclaws.
