We played this map tonight, with our family, and had six players. It did not feel cramped, and did not feel like I spent the whole time looking for someone either. Mostly good, non-stop action. I personally like the connectivity, with all the passageways. At most times, there were always one or two people to fight with. JonnYReds has a lot of deterioration and decay in his maps, and this is no exception.
Everyone in our family had a good time with it, I enjoyed playing it, think it is worth it, and it is a lot of fun.
