Pros:

great range of places to explore
textures are great
Great idea for a map

Cons:

Large ERROR glitches at the start seen that through comments that I am not the only one with this happening
too many locked areas/doors
far too many narrow hallways and cut off areas
too many special infected within the narrow hallways - not much of a chance to kill them due to no space to move
constant losing the way - felt like a rat in a maze tbh
finale was very lacking,though space for it was well planned out
too many sniper rifles that were not needed,too many shotguns also.

Conclusion:

if you have a serious claustrophobia problem don't play this map as its very closed in.
great idea for a map but needs to be given more thought when planning a route through it,dark in some areas,too many parts cut off and unavailable for exploring,finale needs a serious overhaul maybe have it explode or sink like it actual did. over all a decent map that has great potential if done over and the kinks sorted out,anyone playing this with a personal playlist of music should do the finale with Johnny Cash's "The man comes around playing" its totally awesome :) x

Pros:

loved the scenery 
textures were really well done(see cons for the not so great point of them though)
Great Panic events
Good amount of health & ammo available
over all enjoyable to play
Finale was brilliant reminded me of the stadium from the Dark knight rises ( tanks in american football sweatshirts was a nice touch )
Hunter on the outside of the elevator as it went down was also a good touch
Good use of arrows to know where to go also

Cons:

Texture's need to be less as I have played many maps through this site and never had to lower settings to stop the map jittering
too many spitters & boomers over all
Too many jets going over head(not needed two at most is enough)

Conclusion:

Overall a great map that I would play again good environments,not too difficult to navigate through them,ease up on the spitters and boomers placed as well as the jets over head and the texture fix and your onto a winner there :) 

Pros:

Good set of areas not too crowded and easy enough to navigate through each one.
Area's have great detail and are created very well
Like the fact you had to tun on the sprinklers to get rid of the fire to progress further,reminded me of one of the orginal maps that did the opposite and you had to use fire to gain access to the next level :) x
Not too many infected just the right amount to deal with.
liked the fact you had to jump over crates of boxes to get into another area

Cons:

areas were abit too short to get to the safe rooms
finale was somewhat lacking in something
bit too dark in some areas

Conclusion:

overall its a great map to play,it could be abit more challenging and finale could be alot more exciting I reckon. Would recommend this map to friends to play.
