Follow the path of leaves forward, watching out for zombies around you. For the achievement "Dead in the Water", you have to kill 10 mudmen while they are still in water. They look different from the normal infected in that they are naked, bald, and move VERY fast in water. If you have a hard time seeing them, try throwing pipe bombs into water, or try to kill all the enemies while in water. A good place to find mudmen is at the submerged cabin near the end of the chapter. For more info, watch the whole gameplay.
