Not too long. Not a big map but full of demons. All weapons present.

Coop maps? I'll take that
Clearly an early work of a mapper. It won't win any awards, but it was fun enough for the 2 minutes it lasted. Eventually, try making all of the monsters work together within a set to make better fights. Right now, you're just lumping together monsters of the same type and it leaves a lot to be desired.
Ok, thanks for the feedback, i'll try to improve.
