So my first goal was to make a helmet as small as possible but still have the ability to light up and look out. Most of the time the helmets were just way to big when compared to the rest of the armor. I have seen multiple Issac Clarke cosplay costumes on the web and the main thing that bothered me in almost every one was the scale of the helmet. Green LEDs and Coin Ballery holder - 2032 battery Knowing that the RIG would be one of the most detailed parts I made sure to take lots and lots of pics. The great thing about having a game is you can rotate the camera around your figure to get a good look at every angel. I took numerous screen shots and posted them all over my basement wall for reference and inspiration. For this costume I actually played through the game back to where Isaac gets the Level 3 suit. Always try and find as many reference images as you can. When you start to think about making a prop from a video game, movie, etc. As with all of my prop builds reference material is key.
