I don't think there is. Also, more feedback:

• The island after the teleporter looks slightly odd, and the 60 seconds long hold seems cheap. Instead, you should make it a 30-40 seconds long hold with zombies coming before.

• The 'climb' part after the bridge and the island will be impossible on big servers (since you won't be able to see where do you have to jump), and probably unfair towards zombies.

• The one-minute-long hold before the mansion will basically end with all humans holding the windows (crouch spots). You should add another way to exit that building (maybe there's one and I didn't notice?) and make the later hold have a push/teleport to give humans 5 seconds when the gate opens. I know the gate already has a push, but if you are on the other side of that park the wall of zombies won't let any human alive.

• Music fits a lot and the ambience is great, however, you might want to change the fog a bit so that it looks better on the skybox. The plain white fog doesn't blend with the overall ambience and looks odd.

I will keep testing and reporting, good job on this version, although some parts seem to be made cheaply to increase the overall length of the map. While people asked you to extend it, now it looks too forced, and players could get annoyed by that.

EDIT: I think that's it. Adding some randomness to the map would be good too, to increase playability adn to add gameplay changes from round to round.
