Personally I was deeply disappointed with only one level:
I was expecting so much more out of it. A big, sprawling ruins of a city deep underground - something at least as big and scary as New Londo Ruins. Especially since:
- it was BELOW that scary as hell, Latria-like dungeon
- it was the home of one of the intro bosses
- home of the other intro boss (Cathedral) is the best level in the series - why would this level housing the other boss be any worse?
My expectations were super high.
What we got instead - one
and one room with two smaller rooms on the side was disappointment of the year. Great boss, though (didn't know about the gimmick and killed him the hard way) and great atmosphere/ graphics of the - sadly tiny-ass - level...
