Gunner Darklings are summoned creatures in The Darkness.
Gunner Darklings are equipped with a mini-gun that they carry on a sling on their back. Gunners wear a vietnam military type of uniform covering all their body. Gunners shoot at a medium distant range. They are great backup when there's a lot of enemies around.
Jackie first summons Gunner Darkling after Dutch Oven Harry falls off the building on the train tracks. He uses the Darkling to stop a train that comes right at him.
