The detail of this campaign was brilliant
Very long chapters
Cons:
Chapter 3 was glitched. To open the door we had to turn on the power switches. There was no indication of how many we had to turn on, so after wandering the room for what seemed like an hour, we turned on all the switches we could find (around 10), and the door still wouldn't open. Got very irritating so we went back to the lobby and skipped the chapter.
Chapter 4 was just as bad. We had to get a battery to open the door. After looking around for a while we couldn't find a battery to open the door.
Conclusion:
What seemed like a very promising campaign turned out to be a huge disappointment because of the glitched chapters.
