Other welcome changes have been made to player movement. For example, ladders can be climbed, but the speed of the movement up and down can be fast or slow. Getting down a ladder can, in fact, be done quickly, thanks to the addition of sliding down the side rails. Raven Shield will enable the player to not only stand and crouch, but also get in a prone position. While that will make movement that much slower -- with the restriction of having to crab forward on the belly as well as adding a slight, but realistic, side-to-side rock -- it'll provide a steadier shooting position for improved accuracy.
