User blog comment:Spawny0908/UPDATE!!!!: The Free DLC pack is coming in...../@comment-1790321-20110727203633/@comment-2113545-20110727210306

Old: able to actually fight the zombies in sudden death, larger area to play in, able to last for awhile. New: retchers' bile turns explosive and can kill you in a hot second, smaller area to play, after awhile the zombie spawn rate slows down making it hard to last for a long time(not sure if it's a bug or by design).
