Swamp Things are much faster than zombies and have considerably more health, which makes them a much more formidable enemy. It is common for them to come at the player in groups of 2-4, so having a penetrating weapon such as a Paladin's Hammer or any Spear is very useful. Some say that the Piranha Gun is also very effective against these. The Swamp Thing will also stalk the player briefly before attacking.
