Bang bang, pew pew!
Yup, Visceral brought back the foam finger gun for Dead Space 3. Kind of was hoping for something different this time, but it's still a pretty badass weapon. Like before, it's pretty much a one-hit kill weapon, and Isaac will say "bang" and "pew" with each shot.
They did at least add a little more to the gun, as there's now an extra finger for the devil horns effect. Plus, hitting the reload button will literally have Isaac rock out.
To get the gun, just play complete in Classic mode in a New Game + run through.
