It's the Replay function of the ZF-1!
Voilà, the ZF.1. It's light, handle's adjustable for easy carrying, good for righties and lefties, breaks down into four parts, undetectable by x-ray, ideal for quick discreet interventions. A word on firepower, titanium recharger, 3,000 round clip with bursts of 3 to 300, with a Replay button--another Zorg invention--it's even easier. One shot and Replay sends every following shot to the same location. And, to finish the job, all the Zorg oldies but goldies: rocket launcher; arrow launcher, with exploding or poisonous gas heads; our famous net launcher; and, the always efficient flame thrower--my favorite; and, for the grand finale, the all new Ice Cube System. http://www.uselessmoviequotes.com/umq_f004.htm
