Very nice layout. Almost too nice. By that I mean, the r_speeds tend to hit your machine just when the bouts get intense. Nice use of textures especially the effect of filthy sewer water. I like the mirrors in the bathroom. I found myself getting lost looking at my character in the mirror :)
Bots play OK, they sort of wander the map which is good because you never know where they will end up next!
The open silo is very nice but the item placement could be a little better. If you enjoy playing a map with some bots like I do, this one will be a keeper.
Considering the size of the download, give it a whirl!
