Anyone know this map??

In my opinion, the textures/models in ac_factory are more in line with Sauerbraten's style than AC's.

I'll admit, you do have a good point. However...dat realism O.o (assuming the playability is as good as the realistic features).

Sounds like you are basing your opinion on the screenshot, which is exceptional. Frankly it's a bit of a disappointment when you download it. The textures/models aren't as great as one would infer from the screenshot, and some places are cramped. It is nevertheless an impressive map, but I would not personally consider it for inclusion in the official AC package.
