Melissa sez, "Here are some of the best pictures as well as a demonstration video of my custom-made portal gun. I wanted the gun to be as accurate as possible, so I used 3D printed parts that were ripped directly from the game files! After months and months of hard work, I was able to make the gun of my dreams! I took it to Comic-Con, and people loved it! I also met another girl who had the NECA gun, and it's easy to see how some of the details were lost from the game in order to make the NECA gun easier to manufacture."
Awesome Custom-Made NECA Portal Gun
