The NLD-40 is one of the many Non-Lethal Devices used by ETF squads throughout the city. It is intended to be utilized during first-strike scenarios when the element of surprise is crucial.
The bubblegun fires a small mass of semi-hard plastic, which quickly expands and covers the target. The plastic is filled with microscopic replicator bots that immediately duplicate the chemical compounds in the plastic around them and expand the material until it completely encases the victim from the bottom of their feet all the way to the base of their nose, completely incapacitating them for up to three hours.
Small mucus sensors in the bots prevent the plastic from blocking the nasal passageway.
