I thought this map is great... I guess to each his own.
Can be annoying sometimes trying to find the trader (but then you should be heading towards trader before the wave ends anyways..), but I love random door shut mechanism. Changes up the map each time, so you gotta think on the fly where to path. It can be difficult for sure, but that's what I like about it. Full disclaimer, I only played it solo, but will be adding it to my server.

Got locked in the spawn room immediately, had to wait three minutes and camp the zed spawn in the middle for any trash that trickled through.

10/10 would stare at a hole in the ceiling for 180 seconds again

Interesting idea, but... honestly it looks a li'l bit boring, visually speaking. Would it really hurt the map to throw in some features and doodads in some rooms?

I've updated the description to address getting stuck

Oh god, people can get locked in a room and Zeds can get locked out, but what happens then? Does the round have to be force restarted?

very DOOMesque

I guess players will stay at the corner room....I believe.

Keep doing exactly this

The good old days of level and map design

Cool.

Sweet idea dude, I'll give it a go.
