Pros:

Awesome, fast-paced gungame map!! :)
Also good for some other custom game modes such as knives n pistols only

Cons:

,5 off for no HUD (one would argue why you would need one on such a small map, but it's there, so use it)

Bot nav - Bot's NEVER go topside.  I noticed they go as far as camping by the bottom of the stairs on either side, but never go up. 

Conclusion:

1) LOVE it! 
2) I recommend this map for servers up to 8-10 people, maybe 12, if there were bots, and depending on the server configs.
3) Fix HUD and bot nav, I would rate a ten  - ty for a great map, lots of fun!
