I’m writing to endorse the exemplary cosplay prop creating work of Hellhammer Designs. I ordered a Smartgunner’s Headset (from the Colonial Marine heavy gunner in James Cameron’s Aliens) from Hellhammer and was quite pleased as he was an excellent communicator thought the build process. He consistently sent pictures and updates as he worked on the design and was open to input throughout. The project was delivered on time and was a great fit, with a great finish and looked exceptional at distance and close up. Most people don't know it is a foam-based build without close very inspection. I would highly recommend his work to anyone else looking to get a custom project built. Take a good look at his photos and you’ll see what I’m talking about.

Hellhammer Designs made this for us this Christmas. He was efficient and always kept us in the loop. His work is phenomenal.
