I honestly don't think there are any real war machine pep files out there other than the war machine helmet already pointed out. I think you're either going to have to wait a while, get iron man pep files and modify them yourself if you know how, or just do what I did and decide to build an iron man suit instead cuz there are plenty of those lol. Here is a link to the forum where I got all my iron man files, some are finished and some are not. If I were you I'd just stick with the medium to high deff stuff that is finished, it looks good and according to some of the people on the forum that put them together they function well when assembled. Plus there are links to other forums with other great iron man files as well. Good luck and sorry that this wasn't exactly what you were looking for.
