So I w have been researching and thinking seriously about making my first ever Halo costume. I have wanting to for a long time but never knew about the amazing-ness that is the 405th. So after finally deciding to I wanted to build my character that I have created in Halo reach. So to start I have the security helmet on my character so I found the pep file in the armory and scaled it to my measurements. I finally finished my first attempt at doing a pep helmet.here are some pictures I took at midnight.
