Well done - once again - with this map, fetus! From a quick check I can only find 2 nitpicks.
Why do I have to jump to get out of the water (behind & below you, from your screenshot)?
Why is that CGZ zipped in a subdir called ac_watertreatment - leave it out - as stated in packaging guide.

Thanks to all who very kindly took the time to review the map and pass along comments. I've made corrections to textures and minor tweeks to pickup placements.

Will leave as is for now and will let further game play uncover additional areas for improvement.

A very good map. Framerate drops to somewhat 30fps sometimes, but that still doesn't really affect gameplay. You just notice it from the subgun sound, it sounds different then. Good work, keep it up!
