Here is my concept of a gun based on the Big Daddy Bouncer from Bioshock and just in case you don't know what he looks like he's the guy at the bottom. I used a Nerf Maverick for the mod and added trigger controlled lights and drill. I also added a basket so that Mr. Bubbles wouldn't be without a little sister. If you want more information on this gun read my journal entry here [link] and if you want to see the gun in action check out my youtube video here [link] .
Nice job, when I did it I used a Nerf Proton. I love the addition of the little basket for little sister.
Big Daddy Nerf Proton (if interested).
