Firstly It is a lot easier and quicker to do it with your friends so make sure you have a lot of friends when you enter. Secondly you defeat the first boss to open the first gate then you get a quest to defeat a second boss which opens the second gate then you follow through defeat dr von katzenstein then finish by pulling a few leavers then your done PLUS :-) there is also a secret boss called smogger who has a pixie pet take it from someone who has had experience
Same for me i already did it four time's trying to find it but i cant does anyone know where it is?
Two "out of the normal track" chimneys that I can remember:
- Look at your map in that area. You will see a small square section of buildings / side streets right in the middle of the map. Go walk around those side streets. Do "not" follow the yellow arrow, because that leads you right to Dr. Katzenstein, and you will miss the chimneys.
- Also, just before you reach the "last turn" to head into the lab, again do "not" follow the yellow arrow. Turn and go in the opposite direction, away from the Lab.
I went in to defeat katzenstein with a lvl 60 friend but when i got to the katzenstein part someone was already there and iwe defeated katzenstein with her but later it said I still have to defeat katzenstein. Should I start it over? :(
