Well designed maps, esp the ship was interesting - placement of containers and the nasty surprise :-) Custom music was also nice. map felt somewhat easier than the original l4d maps except perhaps larger number of specials.
Cons:
The finale requires running a long way back to the rescue ship. For some it is not even clear when / if the ship has arrived. Unless the final horde is not that tough you will have a hard time making it there esp without grenades. With bots on Adv it is very difficult as they tend to fall and die
Tank placement: well yes it is in tight spots but you can master dodging the tank around columns and furniture pieces :-) BTw remember people y9ou can pull a tank off someone by meleeing it - and running like hell :-)
Pros:
