The Darkness Guns is a power featured in The Darkness.
The third power you gain in The Darkness is a set of Guns created to help the wielder control the Darkness . The Darkness guns act as something like infinite-ammo weapons that draw upon your Darkness Energy instead of physical ammo. There are two of them, both shaped like pistols: the one on the right will fire small bolts of darkness, and acts like an SMG, while the one on the left will fire something similar to a sonic boom and kill most enemies on impact and damaging everything in a small area.
The Darkness Guns are notable for being capable of permanently killing the undead enemies in the World War I sequences in the game; killing them with other weapons will allow them to eventually come back to life until Jackie devours their heart.
