Another MKN map. A central pit with lots of baddies, and a spiral ramp up to the weapons... Easy to get down, pretty tough to get up.
Quite large, or so it seems. The package is so big because the author has included all development versions of the map, along with films for each version.
Just what it sounds like. Suffers from the fall-in-this-pit-and-die syndrome (pits with no way out but suicide).
