An unknown model and quantity of specially designed electronic net guns was ordered by InGen in 1987 to be used for containment measures at their Isla Nublar resort facility. At the time the shipment of the recapture devices was ordered, InGen had not yet had an adult population of dinosaurs, and despite the attitude of John Hammond, Park Warden, Robert Muldoon was discontented to learn that the devices were not fast enough to recapture an escaped dinosaur specimen. In response, Muldoon eventually was able to convince Hammond to purchase two specially designed laser-guided rocket launchers.
