Just installed and had a go at this map, which is quite different from the other co-op maps I have played.

The entire map is held inside a mockup of the film's funeral director home and includes the appropriate sound track and even some of the songs from the original film.

The idea is that you have to gather various parts to baracade the doors and eventually position a safe room door on each entry point.

I played it a couple of times and it was good fun, so if you fancy something co-op in l4d2 and a bit different then this is worth a go.
