The Underground

"It's a hole! Oh, excuse me, a historic hole."

- Nick

Underground is the second chapter in Left 4 Dead 2 ' s The Passing campaign. The Survivors exit the safe room and head through a sham "historic tour under the river". The second leg of this "tour" takes them through sewers where they must open a gate, setting off an alarm that causes a Gauntlet Event. They must then run through the sewer to reach the safe room.
