Good variety of open and closed areas
Plenty of supplies to go around
Playtime ranges from very long to very short but it's always exciting
Excellent visuals, fits right in with the L4D aesthetic
Cons:
Can take a while to set up since the map is pretty big
Slowdown when there's a lot of zombies onscreen
Some odd design decisions, such as Tier 1 weapons near an ammo pile (you wouldn't need to switch out your Tier 2)
Conclusion:
One of the best maps I've ever played, and one of the few that my friends consistently agree to play in. You can experiment with a variety of strategies and no two games end up the same. It's the closest to perfect that I've seen in a Left 4 Dead map. Overall the map looks and plays great, with plenty of details, nooks and crannies, and nothing looking out of place.
More people should play this map and become aware of it. In my opinion it deserves to be recognized as much as the more reputable custom campaigns; even if it's only one map it's done extremely well and should set the standard of quality for survival maps.
