The Flashlight is an attachment featured for the first time in Killzone: Shadow Fall. It is a small module, which mounts to the side or bottom of the weapon when equipped, and emits an extremely bright beam of light which can be used to dazzle enemy players.
The Flashlight attachment also offers a slight increase to hip-fire accuracy for the player when equipped. Also, due to the fact that the attachment is available for nearly all sidearms, the Flashlight is available to all classes in multiplayer.
The size and shape of the Flashlight module will vary depending on the weapon which it is mounted to, however, the beam which the module emits will remain the same size and brightness across all weapons.
