first i wanna say, very nice theme :D but there r some improvements:

the playerstarts, if u want to have ur map gets played in ctf mode, make the playerstarts got "0 1 0 0 0" (red) or "0 2 0 0 0" (blue).

the lightning, i actualy dislike the lightning in the halls, cause there boring, everything the same. But i like the light on the open areas :D.

texturing, actualy pretty nice :D, but i saw u only used 1 face option texturing, maybe you dont know it yet (could be, srry 4 it if u already knew)
but if u press "9" in editmode, then u can texture all sides of a cube in 1 click.

gameplay, i actualy dislike the very long hallways of the map, u could camp very easy there (even u gotta put /zoomfov 10 if u wanna reach the other side of the hallways) and u could get fragged very easy there, if u running trough there with the flag, so maybe u should decrease the lenght of those hallways, probalbly that makes the map less boring 2.

for atm, i say, 3/5 for the map, but i would like to give at least 4/5 :D.

Thanks for the feedback. I've fixed the playerstarts and fixed the problem with the length of the hallways. I'll wait untill I get more feedback before I start making any more changes. If I don't get any feedback, I guess I'll just improvise.
In my head, this theme has more possibilities. Also, the map probably should be more elaborate. I'll release it later (hopefully). Expect more rooms, halls, and such.

its biggest problem, its to big. in everage, you need 10-15 seconds to score (berlin-wall a bit more, on reissen i scored in 6 seconds). try to decrease the size to about 15-20 seconds distance between the flags, the direct (through walls) way takes 40 seconds.
