HALO Armor From Around the World
Here you can see pictures of other people who have completed Halo costumes as well. Take a look and maybe you will draw some inspiration from it. You can see what people can achieve if they set their mind to it. :)
This suit is a custom Halo Reach Noble 6 and he is a member of the 405th. His method used was the standard pepakura and took him 700 hours to complete! The gravity hammer you see in the first image was made by Jim McCrae of Stony Props.
