Wow,
very detail conscience map.
Great layout, very beliveable scenery, clever weapon placement and I loved how if you see a pipe in one room going into a wall, you actually see another pipe of the same texture and size in another room. (this may not sound like much but I see this ignored way too often)
I don't know if you know this, but as far as I know only multi_sources can be masters.
My in-game console when I press that evil button said:
Master was null or not a master
I only saw a few texturing problems, mainly on the big metal doors but the rest were great.
I don't know if you mabye intended this, but on one of the air ducts there is a broken vent that is non-solid, yet you can't get into the ventilation shaft in the first palce because of blockage.
The forklift was a nice peice of brushwork except that when you rotated it you came out with a few invalid solids.
I laughed when I figured out the slime drip thing and I gotta say, that's pretty dang clever. If you mabye sped it up and added another near it I think it would make a very cool effect.
I also like how the green lasers actually kill you, this is once again a commonly forgotten thing to add.
I only wish you would add a bit more detail to the ceilings in a few of your rooms, that way when detail paranoid people like me look up we won't be dissapointed.
Great map, keep up the good work!
