There are some small indoor areas in this one which mix it up a little. DM 2-8 players. It's an art gallery gone horribly wrong. Many oddly placed hallways leading into several larger rooms. There are weapons everywhere, and you can always be picking up something.
Some rooms have camping spots as well, which add to the excitement.
DM 2-3 players. This level is small. Lots of little corridors that link back on it self, suitably placed in a sewer. I felt like it needed a few larger rooms to catch your breath, but that may just be the point. It uses 3d space quite well, and it's never dark even though it may be claustrophobic.
