I'm making ODST armor (the rookie) and I don't know how to make the pieces other than the shoulders and helmet (plus, I can't find a pepakura file about them).
Did you look at all? Not trying to be rude if it sounded that way, but there is a thread that has all the pieces. Ill find the link at post it for you.
And Nightshade has been making ones from the ODST game,also use the search bar if u didnt already its the greatest thing to use when ur looking for somthing
