I have one rule – Increased damage and fire rate. Will damage enemies until they are at 1 HP. Full auto while airborne. Alternative Fire mode toggles the zoom magnification.
Usage & Description
The weapon's special effect can be used to help a teammate achieve a second wind by guaranteeing they get the kill, as well as helping the player complete challenges which require kills under specific circumstances.
When at 1 HP, enemies hit by the Night Flyer will have "IMMUNE" appear.
The source, name, and special effect of the weapon are all references to Batman and his personal code of not killing anyone.
