Quite nice little base map!
The architecture is fairly neat, and the monster population quite reasonable.
But... what really pulls down for me, is the "Beam-in" monsters; for me, this is a big no-no. Quake is quite immersive - but something popping out of thin air completely ruins the (already somewhat stretched) illusion of reality.
There is quite a few ways to send in reinforcements unnoticed. IMHO that gives a much better game experience.
Please carry on; i'm looking forward to see the next map!

Thanks for your effort, and thanks for sharing!
