- The sewer is just one huge maze.. Its really not hard to go through since there most of the time when you enter an area, theres only one door going out. I noticed 2 rooms with more than one exit, and the piece of advice I can offer you is this.. Choose the TOP door. What I mean by this is... Don't choose the door on the WEST... Choose the one to the NORTH.. In one area you can clearly see both doors... choose the north door..
