This awesome semi-automatic NERF Longshot gun was built by engineering student — and TechEBlog reader — Philip H. specifically for his university’s Humans Vs. Zombies game. Video after the break. Click here for more pictures.
Although it may not be the first ever made, it certainly is one of the best to date. I would classify this as a prototype, it is far from perfect but it DOES work.
