A stun gun is a weapon in True crime: New York City.
It is only obatinable from the police aromry and is a light weapon. Once a target is chosen, simply hold the trigger until they are neutralized. It is useful as a non-lethal weapon that can be used from a distance.
A glitch allows the weapon to fire single projectiles in precision mode, instantly neutralizing targets. This is done by switching to a melee weapon, then entering precision mode.
Many civilians will use the stun gun on Marcus if provoked.
