Pros:

Huge amount of detail nothing is left out.
Loads of different places to fight the horde
Looks really spooky
Loads of rooms to explore
Guns and other equipment are scattered evenly around the map for intresting gameplay
More than one way to alert the horde

Cons:

Some gas cans and propane tanks would of added a nice touch, especially in the kitchen where i would of exspected at least one propain tank.

Conclusion:

Best survival map I have played to this date. Me and my friend spent about an hour and a half just exploring it and another hour or so playing it. I loved how there was three ways you could alert the hordes by the radio , bowling a strike and the ball game. This is a definate download. Even if you don't like survival download it just to explore it. Amazing.

Pros:

Intresting gameplay, felt like it improved my Left 4 dead shooting skills. Felt very surreal with all the orange and grey(I'm guessing this is what the maker wanted?), a nice quick download.

Cons:

-Very easy to get lost
-Bots get stuck on ladder on 3rd level(possibly 2nd)
-The dev textures are cool for a while but get boreing and unintresting after a while.
-The finale doesn't seem to have any rescue? It said rescue has arrived but i failed to find it.
-no replayable values

Conclusion:

I would really love to see a fully textured version of this, with some more props. Download it if you want to improve your shooting.
