So as I was scrolling through some images of the development history of Dead Rising, I noticed something I hadn't before, some zombies wore orange t-shirts, which are not in the final game.
after examining the screenshots for a couple of minutes I determined that the texture and model are still used in the final game although the color has been changed to a dark greenish grey color(which is actually one of my favorite shirt models).
So knowing this I went into GIMP(basically photoshop) and I moved the slider on color temp again and PRESTO! THE SHIRT IS BACK! Basically this mod adds to the tgs look if you want it, either way I hope you enjoy it, I know I certainly will
