Just find the official reach file thread, as that has everything. Also, use the search bar. Then look at some foam builds because they tend to be alot easier. All you need to do is cut the tabs off the pep and turn it into a template, then trace it on the foam. Then all you need to do is hot-glue the foam together, and plasti-dip it. Then you has halo armor. The foam method is easier than the pep, and takes half the time and money, but looks the same.
