22.2. Blowin' The Dam: Part 2 | Campaign Duke Nukem Forever Guide
Last update: 11 May 2016
At this part of the game you don't have to search for anything, there won't even be time for that. Keep following the yellow arrows on the walls, the EXIT labels and doors with "Emergency Evacuation Route" signs, as the corridor will soon start filling up with water.
At places where the route seems to end, search for characteristic elements pointing you the way, such as red pipes you can walk on. On your way you will also have to kill a few pigs.
Eventually you will the staircase with barrels rolling down - usually red. Every few metres there will be niches on the right which you can use to hide from the falling barrels.
After reaching the top, keep following the red alarm lights until you reach a bridge that will collapse on your eyes. Go down the ladder to the left of the bridge.
The ladder below will lead you straight to a double channel entrance. Enter the lower one (you can't reach the upper one) and let the wave carry you.
