Pros:

-Great detail very believable.

-Map is playable in Co op and survival mode.

-Strong use of  capillary areas in both game modes. 

-Playable at night or daytime

-Director has a lot of areas that it can use to block and redirect the player in the map.

 

Cons:

-Map is very short for Co op.

-Some players will get lost in Co op mode.

-The Credits at the end don't show your stats and are to long and can't be skipped with out just leaving the game.

Conclusion:

Normally survival maps are very boring but this ones use of capillary and detail make it more interesting. I loved the use of the directors ability to alter the level and I feel this is the biggest most exciting part of L4D2 and it's almost used but valve and custom map makers. 

Pros:

-Fun believable maps.

-Strong detail.

-Pretty solid ambush areas for versus.

-Great Mixture and use of crescendo events.

-Ammo, weapons, item placements very well done.

Very unique use environment usage like elevator safe room.   

Cons:

-Can be hard to find your way around in some areas.

-Finally can be very hard if your playing with only the fail bots.

Conclusion:

These maps are very well done and fun to play. Solid versus play. Final map can be very rough on players playing with bots or if your still learning your way around.

Pros:

Good looking map

Fun Co op and versus

Good ammo spawns or/and weapon spawning

For the most part we could find good ambush spots and infected ladders.

Cons:

Some of the indoor areas are to small for the special infected to be really effective.

Found an invisible car.

Conclusion:

This is a good starting map for a campaign an improvement to versus support and maybe a touch longer this map could be a 90+ easy in my book. I have to give it to you most custom versus maps have very little room for spawning or ambushes your on the right path.
