Pros:

-Good textures
-Made for Versus
-Ammo dumps were spread nicely
-Limited weaponry was great
-Maps, while you don't cover a "ton of ground" you surely are up walking for a bit
-Lots of great smoker, jockey, and death chargers
-Water made you slow, made it fun to fight a tank in

Cons:

-Campaigns could use more hordes
-Think adding a special common would be good (mud-men for second part, for instance)
-Maps go from very tight to overtly open... think there should be more balance in usage of spatial qualities

Conclusion:

Obviously in the beta, there still haven't been a lot of added "throwables/melees" but I look forward to seeing a more complete version later. Overall, it was a very nice change of pace from the norm of these custom maps. Loved the lowlands and high points. The setting of the map seems well thought out and exceptionally planned. My only point though, would be after going through the river area into the cityscape, would be a transition back, or keep it in the city for the rescue/escape. Would be nice to see a ladder at some points. Also, those large drops from 30+ feet incapacitate you. They should kill you. 

Pros:

Great Texture
Spectacular Look
Overall Great Model

Cons:

no facial animations (to be expected)
makes VS/Scavenge games crash often

Conclusion:

Wonderful mod for campaigns and such, but you must remove for competitive modes.
