The Nail Gun is a item/weapon that is used by Avery Marx in the game Shadow Man and and optionally by Mike/Shadow Man in Shadow Man: 2econd Coming
Avery Marx can be seen wielding a dual pair as his choice of weapon when being confronted by Mike/Shadow Man at the former's hideout in Queens, New York. They seem to do low damage, but are still a threat.
- In 2econd Coming, Mike/Shadow Man can acquire a nail gun at the Wild at Heart bar. It is considered as more of an item in this game and deemed a poor substitute for a actual weapon. Nevertheless it is still capable of killing enemies at low damage and nails as its "ammunition" for this item can be located around Louisiana.
