Fallout Reanimated, released on Nexus Mods a couple of years ago, dramatically improves the way the characters move, hold guns, and shoot. The creator of this mod is a professional animator. Unfortunately, he couldn’t finish his project, but even the work that he had done is much superior to the original animations of Fallout 3.
Although the gameplay videos for Fallout 4 show an improved game physics and animations, fans still consider it to be lacking the necessary flexibility of character movements, which can be found in so many other current games. So, this is another department for modders to consider for the future development.
