So I started this piece after Spacedllama suggested it to me seeing as how I can name almost any gun file in the game off the top of my head, and where it is located. But I am going to be posting a simple version here for the sake of space, but please download the attachment for a MUCH more in depth guide to where files are located, and what they do. I will detail out more whats in the guide after this. This guide is mainly to help out texture modders, so I am assuming that this would be the right section. But if not feel free to move it.
So below is a list of every gun in the game (MP anyways) followed by the name of the file, and then comes the IWd in which it is located. Like so:
Name of actual file
IWD where its located
So lets begin.
Sub Machine Guns
IW_07Barret .50 Cal
Now for the actual txt file I am going to attach. It contains MOST if not ALL of the files associated with EVERY gun in the game, locations, and a semi-detailed description of what any other files may be. This IS a V1 however, and a few things are left to question. But thes questionable files are not too necessary for modding, but will be fixed for V2 anyways. If you find any non-grammatical errors please let me know here. They will be fixed in V2 with thanks/credit to you.
(note: I had to upload as a .zip because the max size for a .doc is like 19 kb. So extract, then open with wordpad.)
