Machine Gun/ Grenade Launcher[]

Harley's Machine Gun

Arkham Knight[]

Harley's main weapon in Arkham Knight's story mode. Although she never actually fires it during the game, it can be heard as a Game Over consequence if the player takes too long rescuing Robin. After the screen goes to black, a single shot can be heard accompanied by Harley's laughing and the sound of a body falling to the floor, inferring that she used it to kill him.

The gun appears to be based on a M249 SAW machine gun and was haphazardly duct-taped with a M203 grenade launcher. It was decorated with pink dice, a picture of Joker, and female signs.

Modified Flare Gun[]

Arkham City (Harley Quinn's Revenge)[]

Harley used it in her boss fight to shoot Robin when he was looking for the key to save Batman, and used it again when Batman was fighting against the Mechanical guardians of Wonder City. Her gun was decorated with diamonds symbols and it's called the "Bat Killer".

Arkham Knight[]

It had a small reappearance in Arkham Knight, where it was part of Harley's second GCPD display after she was defeated in Panessa Studios.
