Have Nerf gun, will mod.
Steampunk Nerf weapons are not on my list of favorite things, but artists keep churning them out. This tri-barrel blaster design by Nerfenstein is cool and has a nice Batman touch. It started life as a triple barrel grapnel gun that was marketed for The Dark Knight Rises. It didn’t get great reviews though so Nerfenstein decided to turn it into a prop. All it took was some custom decals, paint, aging, and time (probably several hours). I think the results look neat!
