MAP29: Odyssey of Noises is the twenty-ninth map of The Plutonia Experiment. The music is "At Doom's Gate". Odyssey of Noises is one of the most expansive and difficult of the official Doom levels. Like some of Doom II's middle levels, it resembles a city, complete with roads running between the numerous buildings. There are also several lava-filled craters, the biggest one at the south end of the level. Because of the level's layout, it is very unsafe to be out in the open, since you are exposed to attack by monsters sniping from numerous windows almost everywhere in the map.
