Pros:

Scripted events
Unique alien-pods
Creepy/eerie scenarios/mood

Cons:

Textures a bit bland
Boxy environments
Some areas too big/bare

Conclusion:

Although this one did not have as detailed environments as a couple of the other space maps, this one stood out to me because of the scripted events. A bay door opens and a spaceship floats in, opening its door to reveal 100s of zombies! Excellent! Then having the alien-esque pods where jockies would pop out at you, loved it. The pyramid battle was a very creepy spot, it seemed very alien. 
It really was like playing through a story, an alien race maybe dabbling or exploring something they shouldn't have, and now there's zombies everywhere. 
And it's a campaign, my favorite game-type. Well worth a play-through.

Pros:

Amazingly textured, all mesh together really well
Lots of places to go 
Many items scattered around the station
Details details details
Auto opening sliding doors
Rotating spaceship! 

Cons:

Auto starting
Some doors would get 'stuck' and not open for me

Conclusion:

GORGEOUS map! I just love to run around this one. There are details EVERYWHERE; a trapped boomer in the infirmary, tank in a specimen jar, garden room, all the rooms/areas have their own logos/labels, control panels by the doors, maintenance tunnels, etc. Amazing map, I just love it. The flow of the map is also just great, very easy to go around from one area to the next, lots of ladders, tunnels, and hallways. 
Some of the automatic sliding doors wouldn't open for me sometimes, maybe having a door switch to manually open some of therm would help out.
Would love to see a campaign of this.
