This is a nice looking map with good solid construction, texturing and lighting. There was a few things that really annoyed me however. The main problem I had was that there is a few *open from above* cells which are easy to fall into, and hard to get out from. You can't shoot through the *force field* and touching the force field does little damage to your health. The only way out is a slow painful suicide by repeatedly bumping into the force-field, or a console kill. Bots seem to hang around outside in one main area for some reason. A donotenter texture here might have kept them moving around the level more.
Not a bad map, worth a look for medium sized games.
