Sewer Zombies

The Sewer Zombie is a type of Zombie that appears on the map Train Tranzit. They will only spawn if one of the players is standing on the train tacks, in which case they will continue to spawn and attack that player until the player either dies or moves from the tracks. The Swere zombies are extremely fast and agile, rocket launchers are useless against these zombies due to their agility, as they will simply move out of the way.
