Negatronic force field

Negatronic force field emitters produce a type of energy shield. This technology was developped by the Vok. Swindle had the foresight to buy some off of them, lest someone might wish him harm.

"Negatronic force field emitter. A little something I picked up in an arms deal with the Vok of Nexus Zero. Nice creatures, the Vok. If you're ever in the Nexus Zero area, do yourself a favor and check them out. You won't be sorry."
