I had a chance to run around this one, and I think it holds a bit of merit. That is to say, I liked it, but it's really chunky. The space feels right, and I really like the cool care package features built into it (not to mention the custom content packed with it). But since it stands up for comparison, I must admit, there is another CSS version of this map I prefer. In fact it's already linked on the Pit:

Now I understand this one is still in Beta, so here are the changes I would make:
HDR: I like the HDR and the bloom it provides, but my goodness it feels a bit overdone in this map. I think it should still be a bit blinding, but I would tone it down just a little bit because it becomes somewhat distracting when peeking your head out around the corner, you have to wait to see what you're looking at and then you get shot.
Blockyness: The rooms are really large; the props placed inside them seem really out of place. I like the outside structures, I think they fit, but the rooms of the actual houses just feel really big. Did you use the 'dev_' textures to scale things first?
Gameplay:Is this considered an AIM map? I mean you include the weapons, but you can still buy? I really like the map btw, that always makes the map feel a lot more professionally done.
It's a fine map, but the chunkyness of things really is distracting to me. I like my maps to feel well proportioned, otherwise they feel like game arenas and nothing more. And by 'well proportioned' I mean, feel realistic. The map doesn't feel realistic enough in translation between the materials and their use. That's not a crit on the original Nuketown in COD: BO, but in the way you tried to mimic it in this Source port of it. It just feels somewhat blocky and not to scale.
Nevertheless, I didn't get to play with anyone yet, but it feels like a fun map, and just like the original, I wouldn't change anything about the setting or layout. Just a little farther and I could consider this map 4 stars or even 5.
Thanks for posting!
