The Drains

The Drains is the second chapter of the second campaign, Death Toll. The Survivors start off in the safe room with the usual Tier 1 weapons and supplies. Upon leaving the safe room, they find that they are near a drainage system of some sort. They climb through the drains, and after fighting a horde, come out near a table, possibly containing Tier 2 weapons. They continue through the drains, sometimes fighting a horde. They come out of the drain, and into a flow control room. While avoiding a witch that sometimes appears, they activate the flow control gates, which lowers a bridge with them. The survivors cross the bridge, check a nearby room for medical supplies, fight a horde, and surface into the light. After fighting yet another horde, and possibly a tank, the survivors enter the safe room inside a caboose, ending the chapter.

A glitch in this level is when you are at the main chamber with the metal ladder surrounded by a rib of metal, if you try to go down that ladder while Normal AND/OR special infected try to go up, they will not be able to. The Normal infected will also automatically die once you move out of the way. (So far only seen on the PC version)
